This is why ls is fast on it, but when you tell it to restore it then takes a little time. Sorry, I didn't explain very well. Use mdconfig to create a device backed by a dumpfile. Then factor out the code from restore to treat that layout as a filesystem. Conceptually, it'd be similar to mount_cd9660. Which is another way to ask the question: does anything besides restore(8) understand the dumpfile format? libarchive does not, unfortunately. If you want proper interactive backups, I'd respectfully suggest you start using rsync incremental backup, for which I have a script sy home I'd you're interested. It's malus versus citrus, but it's always interesting to see alternate approaches.___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

I don't think so.
