msi.log. To find the directory where these files are located in Windows, do as follows:
Windows users can find the files via
My Computer. Additionally, there is an automated way of sending us the required files - please see our page on
log file collection for Windows.
Mac users can find the files via
Finder but may need to run
[Go to Folder...] and type or paste in the above-mentioned folder
name in order to locate the files. Please also note that the configuration files are in
/Library/Preferences/Tivoli Storage Manager, not
the (always empty) folder
/Users/<your-username>/Library/Preferences/Tivoli Storage Manager.
Backup is intended to provide a mechanism for securing your current, active files: that is files and data that are resident on your local disk and by implication actively in use. It enables you to recover your disk to its most current state in the event that it is lost (for example, hardware failure); it also enables you to recover a file or files that have been lost (for example, accidentally deleted).
Archive is for the long-term storage of data which is considered to be of value to the university. It is held independent of any files' continued existence on your local disk. Archived files may be removed from the local disk on your computer if required (for example, for space reasons).
Yes. The HFS supports VPN-based backup for systems that are registered for the desktop backup service. This allows the backup and restore of important University data from anywhere in the world using connections via the University's VPN service: please see further our page on VPN-based backups.
The reason for this is because the original deleted node was probably registered to a different server than the newly registered node. To resolve follow the instructions on removing and reinstalling the TSM Client.
Further Explanation: In order to spread the load of new registrations, the HFS team change the server on which new TSM nodes are registered. [Odd numbered HFS servers (OX_HFS_B1, OX_HFS_B3, OX_HFS_B5, OX_HFS_B7) are for desktops; even-numbered (OX_HFS_B2, OX_HFS_B4, OX_HFS_B6, OX_HFS_B8, OX_HFS_B10) are for servers.] One user may therefore have accounts spread over several different HFS servers. If a user de-registers an old account from, say, B3, and re-registers, then the new account may come out on, say, B7, if that is where new registrations go. When he/she tries to install, the TSM installer will pick up on all the old settings it finds in dsm.sys/dsm.opt and will try to contact only B3. But, as the user says in their question, we deleted that old B3 account, so the installer finds no account there. So the B7 account will be ignored by the installer and the user can’t run TSM.
Your TSM backup is unlikely to be affected if your machine is moved, even if it moves to a different part of the university network. However, if it is renamed and it is also running Windows, then it is likely that it will resend all its data, which may cause your account to be locked. Please see further our page on renaming TSM nodes.
For a discussion of the various aspects of this subject, please see our page on TSM security.
Filespaces within TSM are typically subsections of nodes that have previously been backed up. For example a node (desktop, laptop or server) may have several physical or logical disks contained with them - these would locally be seen to as c:\, d:\, e:\ etc. As the TSM Backup is required to run with some administrative privileges it backs up the data using Administrative shares that access directly into the root of each drive letter whilst using the UNC for the client, these are generally seen as \\testpc\c$, \\testpc\d$, \\testpc\e$, etc.
If you are using the Graphical User Interface (GUI) click on
About TSM. The screen will display the relevant information, such as Version 6, Release 4, Level 0.0. Click the screen to close it and return to the TSM hub window.
On a Mac, you can alternatively select
[Tivoli Storage Manager]>
[About Tivoli Storage Manager]from next to the Apple logo (i.e. at the top left corner of the screen). Please note that this does not always give correct results: if you do this after having run TSM Tools for Administrators (which is the recommended method of running TSM on a Mac) then you will be told that you have TSM 1.0; if you do not run TSM via TSM Tools for Administrators, then TSM 6.3 and 6.4 will mis-report that you are running TSM 6.2.
- If you are using the Command Line Interface (CLI) you should, on starting the client see the Version, Release and Level displayed above the tsm> prompt.
There are several ways to check that your backup was successful, whether you only back up manually, only use the automatic schedules, or both. Please see further our page on how to check that backups ran successfully.
|Backup Session Duration||10 Hours|
|Transfer Speed||Average of 10KB/sec over 2 hours|
|Maximum File Size||Same as Daily Limit (below)|
The HFS limits data uploads by imposing a daily quota. If you exceed this amount then your account will be locked out - this is necessary in order to ensure fair use of the HFS. The limits are as follows:
The total data backed up by a node in a 24 hour period is not allowed to exceed the daily backup quota. That 24 hour period is linked to the operation of the HFS service but typically starts in the early hours of the morning.
If you exceed the daily transfer limit then you will receive a mail headed "HFS backup cancellation report": if this occurs please see our section on HFS backup cancellation reports.
If you need to send more than the daily limit then you can stage your backups by limiting the amount that you send each day. If you need to do this, please see the FAQ item 9.12. How can I limit the amount of data that I'm backing up?.
Unfortunately we cannot accept more than the daily limit for each account. This is because of the way in which newly-received data is processed: it would delay our daily processes the next day if we were to receive an excessively large amount for a single account.
- Start a manual backup, using the appropriate instructions from our section on Using TSM Backup & Restore on your client platform.
- In the Task List window, click on
Report; this opens a Backup Report window that shows the running total (listed as
- When the total is approaching the limit, close the
Backup Report window and click on
Stopin the Task List window.
TSM will inspect your local hard drive(s) and any locally-attached external drives and by default will back up all the files that it finds there. However, for a variety of reasons, some files are excluded from backup. A list of excluded files can be found on the HFS Policy Pages.
The HFS keeps up to two copies of any one file that is backed up. For information on how long files are held for, please see section 9.18. How long do you keep data for?.
- New Files
- New files are backed up during the incremental backup and added to the backup set.
- Changed Files
- If a file that has been backed up once is then modified, then the original file is retained in the backup but marked as inactive, and the modified version is backed up and marked as active; only the currently version and the previous version are retained in the backup.
- Deleted Files
- If a file that has been backed up once is then deleted from your file system, then the file is flagged as inactive during the backup process. This file will still be held in the backup dataset for 90 days, at which point it will be removed and no longer be available to restore.
If you do not back up for four weeks then you will receive a warning mail headed 'Old data on the HFS'. Another will be sent after ten weeks of inactivity, warning you that your data will be deleted in four weeks' time. After that point, if we have received no response, then the filespaces/accounts listed in the second e-mail will be deleted. More information about these mails is to be found in our pages on Standard TSM emails: old data on the HFS and deletion policy.
Perhaps, however, you are unable to run a backup because e.g. you are out of Oxford or away on leave. If that is the case and you cannot run a backup for more than two months, please contact email@example.com and let us know the reason, and also the date when you will be able to back up again. We will then put your data on hold until that date.
Generally, the HFS service is available 24/7. However, as with all systems there is from time to time a requirement to update the software and device firmware that underpins the service. Where this requires limiting access to some or all elements of the HFS Service, such interruptions will be advertised to the itss-announce maillist and on the IT Services Status Page, where real-time availability of all IT services can be checked.
The answer to this question falls into two parts. Data that has been backed up to the HFS is, if it still exists on the local disk, retained as long as the drive/partition that sent it continues to back up to the HFS. Data from drives that have ceased backing up for 90 days is subject to deletion, in accordance with our deletion policy; up to three warning e-mails are sent before such deletion occurs.
- Desktop/laptop backup policy
- Server backup policy
All data covered by the Nexus groupware solution - including e-mail, calendars and SharePoint data - is backed up automatically to the HFS, directly from the Nexus servers. There is therefore no need for Nexus users to back up such data using TSM.
For details on the backup and restore of data held on Nexus, see the Nexus (Exchange) service level description.
