BXadmin:AFS Backups

afs-backup.pl and associated scripts are here: http://github.com/phalenor/afs-backup

Installed into /afs/bx.psu.edu/service/afs-backup

Should probably make that /afs/bx.psu/edu/service/afs/backup ?

Testing directory is under testing/, with testing/etc/ -> etc/ and testing/var/ -> var/

Directory layout:

• var/
  • acl/
    • <volume name> - contains acls for that volume
  • log/ - contains dsmc logs right now
  • mounts/
    • mounts-by-path
    • mounts-by-volume
  • tmp/
  • vldb/
    • vldb.<date> - these should be routinely gzip'd
• etc/
  • common/ - config files common to all backup hosts
  • hosts/
    • <short hostname>/ - config files for <short hostname>

Config files:

• basepath : Usually /afs/<cell>. This is used if paths specified in *-by-path files aren't relative
  • TSM mode
  • dsm.sys.head : The top of the dsm.sys file to be generated
  • exclude.list : TSM exclude file
  • tsm-backup-by-path : List of path regexes to backup. Can prefix entries with ! to explicitly exclude.
  • tsm-backup-by-volume : List of volume regexes to backup. Can prefix entries with ! to explicitly exclude.
  • tsm-policy-by-path : List of path regexes and the TSM management class to bind those paths to, separated by whitespace
  • tsm-policy-by-volume : List of volume regexes and the TSM management class to bind the shortest mountpoint for those volumes (by number of characters) to, separated by whitespace
