Backing up blobspaces
It does not matter whether you back up the logical logs or blobspaces first.
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.
