To back up blobspace data
- Close the current logical log if it contains transactions on simple large
objects in a blobspace.
- Perform a backup of the logical logs and blobspace as soon as possible
after updating simple-large-object data.
Warning:
If you do not back up these blobspaces
and logical logs, you might not be able to restore the blobspace data. If
you wait until a blobspace is down to perform the log backup, the database
server cannot access the blobspace to copy the changed data into the logical
log.
