Uh. If backuping up a live database from a snapshot is not trustworthy, either the snapshot facility is broken or the database is broken (i.e., not crash-safe to begin with). That said there are plenty of other reasos to use proper dump tools (data portability, confirming the ability to actually read all rows from a table, using a more often exercised code path and perhaps less likely to have edge case bugs, etc). -- / Peter Schuller PGP userID: 0xE9758B7D or 'Peter Schuller <peter.schuller@infidyne.com>' Key retrieval: Send an E-Mail to getpgpkey@scode.org E-Mail: peter.schuller@infidyne.com Web: http://www.scode.org [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.11 (FreeBSD) iEYEARECAAYFAknLirsACgkQDNor2+l1i31ZEgCdEqNBg7vRQorydzFVUmRMFI3H UVcAnA6sie1EgWonOybD7Ce/RRoZ/DgD =3wsx -----END PGP SIGNATURE-----
