How to recover AFS files from backup

The COOL and CORAL internal areas, as well as other AFS project files and AFS user files, are backed up. See

Recover AFS user files from the last backup (yesterday)

If you need to recover AFS user files from yesterday's backup, e.g. for user cooluser, just look in /afs/

Recover AFS project files from the last backup (yesterday)

If you need to recover AFS project files from yesterday's backup, follow the recipe in

  1. Find the volume name.
    • For instance: fs exam /afs/
    • The example above will return p.sw.lcg.coolint
  2. Examine the volume and its backup.
    • For instance: /usr/sbin/vos exam p.sw.lcg.coolint
    • For instance: /usr/sbin/vos exam p.sw.lcg.coolint.backup
  3. Mount the volume backup.
    • For instance: fs mkmount ~/temp p.sw.lcg.coolint.backup
  4. Copy the files.
    • For instance: ls ~/temp
  5. Unmount the volume backup.
    • For instance: fs rmmount ~/temp

Recover AFS (user or project) files from an older backup (older than yesterday)

If you need to recover files older than yesterday, just use afs_admin recover <file>.
