TSM backup/restore

Pre-cautions:

• Application/Database teams are responsible for their application/database backup and restore.
• First restore the files from TSM to a temporary location, and then restore it to original location.

Pre-checks:

• ‘dsmc q session’ – the session between TSM client and TSM server is to be active

Installation Instructions:

• To initiate a backup of a file or directory: 

“dsmc ba /file-dir-location”   

“dsmc ba ‘/dir/*’ –sub=yes”

• To query the backup status:

“dsmc q ba /file-dir-location”

• To take the incremental backup of filesystem

“dsmc incr /fsname”

• To take the full backup of filesystem

“dsmc ba /fsname”

• TSM Config files:

/usr/tivoli/tsm/client/ba/bin/dsm.opt   [contains filesystem to be backed up in the scheduler]

/usr/tivoli/tsm/client/ba/bin/dsm.sys   [TSM configuration file]

• TSM error logs:

/usr/tivoli/tsm/client/ba/bin/dsmerror.log

/usr/tivoli/tsm/client/ba/bin/dsmsched.log

• To query the scheduler:

“dsmc q sched”

• To restore a file from the TSM backup [non-interactive]

“dsmc rest /sourcedir/file1  /destndir/”

• Just restores the file/dir to the specified destination directory. Or pick up from the list and restore [interactive]

“dsmc rest /sourcedir/* /destndir/ -sub=yes –ina –pick”

• Note: rest stands for restore; sub stands for subdirectories; ina stands for inactive.

Verification / Postchecks:

• Verify the backup with “dsmc q ba /dir/filename”  [q stands for query]

Backout:

• Restore the old file.
