Hi all, if we change the ownership (chmod/chgrp) or the ACLs of files/folders on our GPFS-filesystem, all affected data will be backed up again from TSM because the ctime was changed - same behaviour on a XFS filesystem. We often have to change recursively the ACLs of a 15TB-folder and so this 15TB are backup up nearly daily... I understand the necessity of backing up metadata as ownership or ACLs :) But is there an other possibility?
Can we backup just the metadata of changed files instead of all the data? Depends this on the filesystem? Thanks, Alex
