Backing up blobspaces

About this task

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

To back up blobspace data:

Procedure

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.

Results

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.
