Maybe. I'm confused by your question, but: * If the data directory is on an FFS2 volume on a FreeBSD machine, you can use mksnap_ffs to back it up, and that approach is actually recommended for PITR-type backups. * If the data is mounted via NFS or something similar and the filesystem is not FFS2, then snapshots are not available on FreeBSD. -- Bill Moran http://www.potentialtech.com ---------------------------(end of broadcast)--------------------------- TIP 6: explain analyze is your friend
