Restoring ACL-protected VOBs
Restoring ACL-protected VOBs calls for special attention to handling the ACLs correctly.
Restore from backup without ACLs
After restoring from a backup without ACLs, run cleartool checkvob -fix to repair discordances (such as misprotections) between the VOB database and container ACLs.
Restore from backup with ACLs
To restore from a backup with ACLs, restore tools must have abilities to preserve ACLs. As mentioned elsewhere, cp may need -p argument and tar may need -p argument to preserve ACLs. If you run checkvob and it returns problems, such as misprotections, use vob_sidwalk -recover_filesystem to fix the ACLs problems. Both local and NFSv4 file system have the same restore procedures.
