Ahh. I see it now. By stat'ing the destination instead of the snapshot directory, you get the added bonus of being able to identify which snapshot versions actually have a changed file in it. I like it. The only negative I see about that is: Some tools such as TrueCrypt intentionally keep the mtime on their files constant. It would be nice to be able to identify authoritatively which files have changed or not, without relying on the mtime. But I think that's a corner case, and nothing that can be improved for now. So, this is probably the best strategy, I agree with you. ;-) Stat the file itself, not the snapshot directory. > > How in the heck can you identify when a snapshot was taken, if you're > not > > relying on the name of the snapshot? > > "zfs list -t snapshot" lists in time order. Good to know. I'll keep that in mind for my "zfs send" scripts but it's not relevant for the case at hand. Because "zfs list" isn't available on the NFS client, where the users are trying to do this sort of stuff. > >> It would be cool to only list files which are different. > > > > Know of any way to do that? > > cmp Oh, no. Because cmp and diff require reading both files, it could take forever, especially if you have a lot of snapshots to check, with a large file or set of files... Well, what the heck. Might as well make it optional. Sometimes people will just want to check a single small file. > But since the world has moved onto time machine, time slider, and > whatever Windows users use, is this tool relegated to the CLI > dinosaurs? ;-) It's not hard to add an IE context extension and/or create some other gui frontend in whatever OS you're using. But command line comes first. _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
