Can tar be made not >to modify the ctime, mtime and atime? This is what the general consensus on the amanda-users list has been for some time now. Linux ext2 dump/restore is massively broken. If you're using something like XFS though you can probably get away with xfs_dump/restore. Personally I prefer to use tar anyway. A tar archive is restorable on most any unix without requiring a vendor/filesystem specific restore binary be available. That's one less point of failure in restoring the backups. The only place where tar really won't cut it is when you're using special filesystem features not traditionally supported by unix, such as filesystem ACLs. Brandon D.
