Michael, I don't believe you can use journal-based-backup for network connected file systems. If you want to avoid incremental backups walking a NAS filesystem looking for changed files, you can look into NetApp (which TSM supports with snapdiff incrementals) and IBM Sonas. Snapdiff uses a NetApp API which compares two snapshots, producing a list of changed files which TSM then backs up. This eliminates the time it takes to "walk" the filesystem looking for changes, and this can dramatically speed up incremental backups. We use this, but we also do a monthly walk (called a rebase) just to catch any edge cases that snapdiff misses.
I believe Isilon also has a similar unsupported API, but as it was not supported we opted not to go with Isilon. ..Paul At 11:42 AM 8/12/2016, Michael P Hizny wrote: >All, > >Does anyone know a way to use journaling in TSM on a networked file system. >If you go through the wizard, you can select to journal the local file >systems, but there is no option to journal network connected file systems. >We can back them up by specifying them in the opt file as: > >DOMAIN "\\xxx.xxx.xxx.xxx\folder1" >DOMAIN "\\xxx.xxx.xxx.xxx\folder2"But can you set up and use journaling on >them? > >Thanks, >Mike > >Michael Hizny >Binghamton University >mhi...@binghamton.edu -- Paul Zarnowski Ph: 607-255-4757 IT at Cornell / Infrastructure Fx: 607-255-8521 719 Rhodes Hall, Ithaca, NY 14853-3801 Em: p...@cornell.edu
