Actually, they aren't - the archive format is very stable. (This is a fairly important requirement - you don't want to suddenly be unable to restore your backups after an upgrade). I can restore dumps made on FreeBSD4.8/i386 and FreeBSD4.9/alpha on a FreeBSD-current/amd64 system without problems. It's possible that you might have problems with a backup made using a very recent dump on a very old restore if you've used filesystem features that didn't exist when that restore was built. -- Peter Jeremy [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.10 (FreeBSD) iEYEARECAAYFAknLSfAACgkQ/opHv/APuIcudACgxNIAZcEZ2+95dCWS8+S1eIG/ 4msAn3S4G8J1LQPI/oCK+QF+teL5OmKF =eC27 -----END PGP SIGNATURE-----
