6. Retrieving your data

6.1. Retrieving selected files

Unlike the TSM GUI, you cannot get a straight list of archived files which you can retrieve. As a result you will probably wish to query the server for a list of files, before retrieving a (sub)selection of them. Basic queries are listed in the examples above ( see section querying the server ). Having done that, the basic syntax for archive file retrieval is dsmc retrieve source-file destination-file. If the destination-file is omitted then TSM will retrieve the file(s) to their original location. If a file of the same name is found in the destination location, TSM will prompt you whether to overwrite or not the current file.

The simplest form of retrieve is for a single file or file pattern

  tsm> retr join.jpg

The file may be wildcarded to specify more than one file, as below.

  tsm> retr j*.*

6.2. Retrieving multiple files and directories

To retrieve all files in a directory add a trailing slash on the end of the file path:

  tsm> retr "C:\My Documents\html-docs\Mac\"

When specifying an alternative destination for retrieved files, remember to terminate it with a trailing slash:

  tsm> retr "C:\My Documents\html-docs\Mac\"  C:\retrieve       # Wrong !
Retrieve function invoked.

--- User Action is Required ---
File '\\cles.oucs:c$\retrieve' exists

  tsm> retr "C:\My Documents\html-docs\Mac\"  C:\retrieve\      # Correct !

To retrieve all files in a directory tree, add the trailing slash on the end of the file path and include the -su=yes

  tsm> retr "C:\My Documents\html-docs\Mac\"  C:\retrieve\  -su=yes       

By default TSM will create a subdirectory in the destination directory for each lowest level source directory, and place files in there. Thus, in the example above, if there were two subdirectories new and old under \html-docs\Mac\, then TSM would create two subdirectories named new and old under C:\retrieve\. This behaviour can be modified by using the -preservepath= option - see the online help for worked examples of the four values this option can take.

6.3. Retrieving selected archive versions of files

Where more than one version of a file has been archived, then a basic retrieve using just the file path will cause TSM to retrieve each version of that file, starting with the earliest and ending with the most recent archive copy. Once the earliest copy has been retrieved, TSM will prompt to overwite it with each more recent archive copy. To prevent this happening the -description= option should be used in both the query of archived files and the subsequent retrieval of files.

Thus, to query the server for just a subset of files archived under a certain path, run something like:

  tsm> q ar /scratch/test1/j*.jpg  -desc="Jenkins*"
       Size  Archive Date - Time    File - Expires on - Description
       ----  -------------------    -------------------------------

    760,632  28-06-2002 17:18:54    /scratch/test1/j2.jpg Never Jenkins 2nd - 2nd amend
    760,632  28-06-2002 17:22:28    /scratch/test1/j2.jpg Never Jenkins 2nd - 3rd amend
    760,632  01-07-2002 12:01:06    /scratch/test1/j2.jpg Never Jenkins 2nd Final Version

To retrieve just the Final Version of the above files to their original location on the local machine:

  tsm> retr /scratch/test1/j*.jpg  -desc="Final Version"
