Greetings,
I am seeking information related to this subject.
BOL suggests backing up the active transaction log immediately after a
failure, so that the backup can be used in a recovery scenario if necessary.
This is the relevant text from BOL "Transaction Log Backup":
----//
The transaction log backup created at 8:00 P.M. contains transaction log
records from 4:00 P.M. through 8:00 P.M., spanning the time when the
database backup was created at 6:00 P.M. The sequence of transaction log
backups is continuous from the initial database backup created at 8:00 A.M.
to the last transaction log backup created at 8:00 P.M. The following
procedures can be used to restore the database to its state at 10:00 P.M.
(point of failure).
Restore the database using the last database backup created.
1.. Create a backup of the currently active transaction log.
---// end of excerpt
If the failure results in loss of the instance and/or the log's parent db,
how would we back up that log? Even if we could, what confidence would we
have that the backed up log was not corrupted at failure time?
Thanks,
PSG
