If you have received this message then some or all of your data will NOT have been backed up. Therefore it is important both to resolve this issue as soon as possible to enable future scheduled backups to run; and also to perform a manual backup to ensure that your current data is backed up and secure.
Within the email there will be one or more Nodenames listed. Since each node has its own unique account name, password and installation of TSM, you will need to repeat this process for each of the nodes listed in the email.
Determining whether the scheduled backup was MISSED, FAILED or SEVERED
- The email will state for each node whether the scheduled backup was MISSED, FAILED or SEVERED:
- For each node, check which status has been given and chose from the following options to continue:
Manual backup - If you already know why this scheduled backup was missed and then you may just wish to run a manual backup.
- The first thing to check is whether the machine that used this nodename has been replaced, rebuilt, or is no longer used.
- If the node has been replaced, rebuilt or is no longer used then please follow the instructions for de-registering the node so that it is no longer on the backup schedule.
- Check the TSM Self-Registration Page to ensure that you do not have two or more similarly-named registered nodes: it could be that one of them is active and being backed up, and the other does not exist and is therefore being reported as missed. If you have nodes registered to you that you know do not represent existing machines, please follow the instructions for de-registering the node.
- If the node is active and you still require it to be backed up then please proceed to the following section.
- If your TSM node is locked then you will not be able to back up to the HFS until it is unlocked.
To check your node's status do as follows:
- Go to the TSM Self-Registration Page.
- Select the problem node and, from the drop-down list provided, choose
[View Client Information].
- If your node's Locked status is Yes then you will need to contact
firstname.lastname@example.org to get it unlocked.
You can do this by clicking on
Request unlockon the aforementioned client information page. When it has been unlocked we suggest running a manual backup so that you can:
- If your node's Locked status is No then also check the Last Password Change date.
If the date shown is over a year old, then your password may have expired and need to be changed. To do this:
- Click on the
TSM Home Pagebutton.
- Select the required node and from the drop-down list provided, choose
[Change Client Password]and follow the on-screen instructions to reset the node's TSM password.
- Windows users will then need to update the TSM scheduler.
- Once the password has been reset, we suggest running a manual backup so that you can:
- Click on the
- If your account was neither locked nor had an expired password then please proceed to the following section.
- Was your machine left switched on overnight?
- NO - Are you registered for the Wake on LAN service?
- NO - Your machine must be switched on to run a scheduled backup. If the machine was off when the schedule was due to run then the schedule will have been missed. You either need to leave your machine on overnight, or to register for the Wake on LAN service. Please see further our page on how to set a machine to switch on and off for scheduled backups. You are advised to run a a manual backup to ensure your data is backed up.
- YES - Check in
dsmsched.logto see if there is an entry at around your scheduled backup time, which would indicate that your computer was switched on. (The location of
dsmsched.logcan be looked up in our list of TSM Options Files.) Did your machine switch on, so that the backup could run?
- NO - If the machine did not switch on, report this problem to the Help Centre as this is an issue with the Wake on Lan service. You may also wish to run a manual backup.
- YES - Did you put your machine to sleep rather than shut it down, and if so are you running Windows Vista or 7?
- YES - A Windows Vista/7 machine woken from sleep mode will return to sleep two minutes after wake-up - so please do not put your machine to sleep if you wish it to be woken up, but next week shut it down instead.
- NO - if you are not a Windows Vista/7 user who put their machine to sleep, proceed to the next step to check if your machine switched itself off.
- YES - Your machine may still have switched itself off or gone into sleep mode, meaning that the scheduled backup
was missed. Would your machine have definitely stayed switched on?
- NO - most machines will go into a sleep mode after a certain period.
To prevent this, you need to set power management correctly, as follows:
- In Windows:
In XP/2003, go to
Power Schemes(tab), and check that
System standbyis set to
Never. Then, if your machine is a laptop whose lid you close when you leave it on for backup, click on
Advanced(tab) and under
When I close the lid of my portable computerchoose
In Vista/7, go to
Change when the computer sleeps(tab), and check that
Put the computer to sleepis set to
Never. Then click on the arrow to go back to
Power Optionsand also check that under
Choose what the power button does(tab),
When I press the power buttonis not set to
Sleep. On the same screen, if your machine is a laptop whose lid you close when you leave it on for backup, check that
When I close the lidis set to
- In XP/2003, go to
- On a Mac:
Energy Saverand check that the computer (not the display) is set never to go to sleep.
- In Windows:
- YES - if the machine was left on and power management is set correctly, proceed to the next step.
- NO - most machines will go into a sleep mode after a certain period. To prevent this, you need to set power management correctly, as follows:
- NO - Are you registered for the Wake on LAN service?
- Was your machine left connected to the physical Oxford University network?
- NO - if you were connected via a VPN connection or not connected to the network at all then the scheduled backup would not have started. You must have a physical network connection to the Oxford University network for the scheduled backups to run.
- YES - if the machine was on and there was a physical connection to the Oxford University network, please see our page on Checking the Client Scheduler for Windows, Mac or Linux/Unix machines.
You should now have performed enough troubleshooting to ensure that you know why the scheduled backup was missed and hopefully put corrective measures in place to ensure subsequent scheduled backups are successful. If you have been unable to determine the likely cause of why the backups are being missed then please follow the steps below for logging calls with the HFS Team with the appropriate amount of data.
If you have not already done so, we recommend that you run a manual backup.
To find out when your next scheduled backup is, please see the FAQ item When is my scheduled backup due to run?.
A failed backup generally means that TSM was successful in starting a backup but that it was unable to complete it successfully. Further investigation is required to determine how much of your data was backed up - it could be some, all, or none of it that got sent to the HFS. Objects on a user's machine that may cause a schedule to fail include:
- Files that are exclusively locked open by another program and cannot be backed up, e.g. database files.
- Files that are corrupt, making them unreadable.
- Files that are excessively large, causing them to make the network connection time out.
- Folder/File structures that breach TSM maximum file length restrictions.
- Folder/File structures that create memory issues on the client machine, causing backup to fail.
Another possibility is that TSM is wrongly configured: if it is looking for a file system of partition that does not exist then such a backup would be deemed a failure - e.g., if TSM is set to back up D: but there is no D: drive present.
If you are IT Support Staff, or are an advanced user and are confident reviewing and interpreting log files,
then please follow the suggestions below. You will need to open the file
dsmsched.log, whose location
on your machine is listed in table 1.
dsmsched.log is opened (on which, see below), you will need to search for ANS entries.
These are in the format of ANS####? - where the # represents a number, and the ? represents either an E (Errors), W (Warnings)
or I (Informational). Informational messages will not be a cause of a scheduled backup failing or being severed.
- Browse to the appropriate location and open
- Once the log is open (this may take a while if it is large), scroll to the bottom of the log file: this is where the most recent information will be.
- Depending on your operating system, you now need to search through the log file. In Windows, select
CTRL+F) to bring up the search box.
- In the search box type
ANS, then select up and click
- Look for ANS entries that end in either an E or a W.
- Open your spreadsheet package.
- Click on
- In the box provided change Files of Type to be
- In the Look in: section browse to the appropriate location and then open
- Generally a box will appear giving you various import options - leave the defaults and select
- The log file will open, with each time-stamped entry from the log appearing on a separate line.
- Once there, select
CTRL+F) to bring up the search box.
- In the search box type
ANS, then select up and click
- Look for ANS entries that end in either an E or an W.
- Excel users - In the search window you can enter ANS????E to search for Errors or ANS????W to search for warnings.
- Open Office users - In the search window click on the
More Optionsbutton and tick the Regular Expressions tick box; then you can search for ANS????E to search for Errors or ANS????W to search for warnings.
For each ANS####E or ANS####W you need to review the text which follows the error code to determine whether this could have been a cause of the scheduled backup failure. You will most likely find the message "ANS1512E Scheduled event ... failed" and at least one other message as well. Examples of common messages that cause scheduled backup failures are listed below.
TSM may send most of your data but ultimately report overall scheduled backup failure if other files are left open. TSM only deems a schedule to have failed if one or more files have been prevented from backup in a certain way - not all file failures cause schedule failures. But Windows in particular does sometimes lock open files in such a way that it causes TSM to call a schedule failed - when really only a small number of files failed to get backed up.
In general, therefore, it is best to close all files and
programs before a backup runs. To locate the problem, first of all please check your
dsmerror.log to see if any file failures were caused by one or
more files being changed while TSM was trying to back up. There may be lines like:
30-01-2008 00:25:28 ANS1228E Sending of object '/var/log/test.log' failed 30-01-2008 00:25:28 ANS4037E Object '/var/log/test.log' changed during processing. Object skipped. 30-01-2008 00:25:31 ANS1802E Incremental backup of '/' finished with 1 failureAdditional information near the end of
dsmsched.logwill show the total number of failed files. In order to find the relevant part of text it is usually easiest to go to the end of the document, and then scroll upwards until you find an end-of-schedule report similar to the following example:
30-01-2008 00:26:04 --- SCHEDULEREC STATUS BEGIN 30-01-2008 00:26:04 Total number of objects inspected: 214,391 30-01-2008 00:26:04 Total number of objects backed up: 16 30-01-2008 00:26:04 Total number of objects updated: 0 30-01-2008 00:26:04 Total number of objects rebound: 0 30-01-2008 00:26:04 Total number of objects deleted: 0 30-01-2008 00:26:04 Total number of objects expired: 0 30-01-2008 00:26:04 Total number of objects failed: 1 30-01-2008 00:26:04 Total number of bytes transferred: 70.20 MB 30-01-2008 00:26:04 Data transfer time: 5.07 sec 30-01-2008 00:26:04 Network data transfer rate: 14,151.96 KB/sec 30-01-2008 00:26:04 Aggregate data transfer rate: 588.20 KB/sec 30-01-2008 00:26:04 Objects compressed by: 0% 30-01-2008 00:26:04 Elapsed processing time: 00:02:02 30-01-2008 00:26:04 --- SCHEDULEREC STATUS END 30-01-2008 00:26:04 --- SCHEDULEREC OBJECT END WEEKDAILY_OUCS 30-01-2008 00:00:00 30-01-2008 00:26:04 ANS1512E Scheduled event 'WEEKDAILY_OUCS' failed.

If you cannot close the file(s) that is/are causing the schedule failure before scheduled backup occurs, then you should exclude them from backup. Files that are continually open - such as log files and database files - would fall into this latter category. See further our pages on excluding files and folders from backup and backing up open files with TSM.

30-06-2011 00:45:56 ANS1134E Drive is an invalid drive specification
- If your machine is a Mac, then this could be due to a bug with early versions of TSM 6.1 for Mac, which do not analyse backup domain statements correctly.
- The listed domain entry does not exist as a drive or partition:
One reason for this could be that a folder/directory
has been specified as a separate domain. The latter will cause an error because only drives or partitions
may normally be used as domains: hence TSM cannot find the drive
/data/fredand so it deems that the schedule has failed. In this case,
/data/fredmust be a folder/directory that is part of the larger partition
/dataor part of the root partition
- Alternatively it could be that a drive is listed as part of the backup domain but is no longer present on the machine. Perhaps the drive has been removed; or perhaps (on Windows machines only) the TSM backup domain contains references to UNC paths that are no longer valid (e.g. because the machine has been renamed).
- One reason for this could be that a folder/directory has been specified as a separate domain. The latter will cause an error because only drives or partitions may normally be used as domains: hence TSM cannot find the drive
- There is a space in the domain name - in this case quotation marks need to be used around the drive name,
because otherwise TSM will assume that you mean several domains. E.g. the above error message would occur
if you wanted to back up the drive
/data/fred backupbut you specified the incorrect
DOMAIN /data/fred backupinstead of the correct
DOMAIN "/data/fred backup".
- If your machine is a Mac, ensure that you are running TSM 6.1.3 or higher - please check your TSM version using our instructions under Which version of TSM am I running? - and if necessary upgrade TSM.
- If this is not a Mac, or if it is but upgrading does resolve the problem,
run TSM (Mac users must use
[TSM Tools for Administrators]) and go
[Backup](tab) and correct your backup domain. If you are running TSM 6.1 or higher, you now need to restart the TSM scheduler: see further our instructions for Windows, Mac and Linux/Solaris on how to do this.
Sometimes TSM may think that the schedule has failed because of a communication problem with the HFS server. In this case, you will be able to tell from
the end of
dsmsched.log that no files failed during the backup. For example, you may see a report in the
latter file like the following:
01-11-2007 16:27:42 --- SCHEDULEREC STATUS BEGIN 01-11-2007 16:27:42 Total number of objects inspected: 31,029 01-11-2007 16:27:42 Total number of objects backed up: 62 01-11-2007 16:27:42 Total number of objects updated: 0 01-11-2007 16:27:42 Total number of objects rebound: 0 01-11-2007 16:27:42 Total number of objects deleted: 0 01-11-2007 16:27:42 Total number of objects expired: 0 01-11-2007 16:27:42 Total number of objects failed: 0 01-11-2007 16:27:42 Total number of bytes transferred: 52.47 MB 01-11-2007 16:27:42 Data transfer time: 106.71 sec 01-11-2007 16:27:42 Network data transfer rate: 503.49 KB/sec 01-11-2007 16:27:42 Aggregate data transfer rate: 219.49 KB/sec 01-11-2007 16:27:42 Objects compressed by: 0% 01-11-2007 16:27:42 Elapsed processing time: 00:04:04 01-11-2007 16:27:42 --- SCHEDULEREC STATUS END 01-11-2007 16:27:42 --- SCHEDULEREC OBJECT END WEEKDAILY_OUCS 10-01-2008 10:00:00 01-11-2007 16:27:42 ANS1512E Scheduled event 'WEEKDAILY_OUCS' failed. Return code =12. 01-11-2007 16:27:42 Sending results for scheduled event 'WEEKDAILY_OUCS'. 01-11-2007 16:27:42 Results sent to server for scheduled event 'WEEKDAILY_OUCS'.In this case, TSM has inspected 31,029 files and has backed up 62 of them. The number of failed files is zero. The TSM client has experienced an error when signing-off from the server and has recorded this as a failure. However, it is clear that the scheduled backup itself has completed and the failure message can be ignored.
This error can occur because the amount of memory (RAM) which the TSM scheduler uses can grow with time, until it may reach a point where there is insufficient free memory for scheduled backups to be able to run. To prevent this, it is recommended that TSM users stop and restart the TSM scheduler periodically: however, if your machine is rebooted regularly then restarting the scheduler is unlikely to be necessary, because the service is restarted every time you reboot.
It is possible, though very unusual, that your machine may run out of memory during a backup and then TSM will cut out. This is most likely to happen on a Mac which is holding a very large number of files (over a million) on one drive. If your backups on a Mac, both scheduled and manual, cut out without warning, please see backups fail to complete.
126.96.36.199. 'ANS4023E Error processing ...: file input/output error' or 'ANS4046E There is an error processing ... the object is corrupted and unreadable' or 'ANS4047E There is a read error on .... The file is skipped.'
If TSM is having trouble reading certain files, then it could be because they are corrupted. If this is the case then you will see error messages in your
dsmerror.log about certain files being unreadable by TSM. For example, they may take the form:
ANS4023E Error processing '/var/log/test.log': file input/output error.
ANS4046E There is an error processing '/var/log/test.log': the object is corrupted and unreadable.
ANS4047E There is a read error on '/var/log/test.log'. The file is skipped.

[First Aid]tab click
Verify Diskor, if appropriate,
- In Unix/Linux, use the command
fsckto check your disk - please refer to your system documentation for the appropriate procedure.
- Intervention at the client (user) end - the user forcibly cancelled the backup/stopped TSM services, or switched the machine off during the backup.
- Intervention at the server end - the backup may have been cut off from the HFS server for exceeding a daily limit.
- Failure (e.g. crashing) of the client machine.
- TSM client machine going into sleep mode/state of hibernation.
- Several large files causing multiple connection timeouts between the server and client.
- Dropped network connection either at the client end, or somewhere on the network between the client and the server.
- Firewall intervention prohibiting/delaying network traffic.
If you are aware of your machine crashing or the backup being forcibly cancelled then you may wish to simply run a manual backup.
To troubleshoot why your backup was SEVERED please follow the above troubleshooting steps provided for FAILED backups.
If you have been through the troubleshooting steps provided and your issue has not been resolved, you need to log a call with the HFS Team by replying to the email you received advising you of the MISSED, FAILED or SEVERED backup (or e-mailing email@example.com) - with the files listed below.
For Windows users we have an automated way of sending us the required files - please see our page on log file collection for Windows.
