NTBackup is native to windows and fully supports backing up exchange in an
active state. So you do not need to shut down any part of exchange if that
is what youre asking. It shouldnt cause corruption just because exchange is
running at the time of backup.
NTbackup does not support mailbox level backup so far as I know so it would
be a disaster recovery backup situation, not an archive situation. You
would have to dump out and restore the entire mail datastore at a time.
you can start ntbackup i think by just typing ntbackup into a run dialog or
cmd prompt on windows, its fairly automated and beyond the scope of this
mailing list to detail how exactly ntbackup works. Basically run ntbackup
and create a nightly job that dumps out the exchange data store before the
backuppc process happens. I have two jobs, one for even days and one for
odd days, they run every other day respectively and overwrite their
respective file each day so I dont have backup file buildup on the system.
As far as vss snapshots, that is fine for flat files but my understanding
is that is a lot like trying to backup a sql database file, you are
backuping up an active database file and who knows what state the file is
in. You really should be doing a dump of the database and backing up the
dumped file, be that exchange or sql or anything else. I'm not entirely
sure how exchange would feel about you trying to restore a flat file of its
database either. You could end up with exchange rejecting the restored
file. I dont entirely know on that last bit to be honest though.
