This option is for backing up only onw copy of an attachment rather than 10,000.  For example, if an email with a Word doc were sent to 10,000 recipients, 10,000 instances of the attachment would be backed up.

If your backup is running within the time window you desire, don't choose this option because message attachments as a whole might not be backed up if the job does not complete: that's right, not one attachment might be backed up.

Then, if you were performing an incremental backup versus a full backup, you have to remember to run a full backup to replace that incremental because of the issue.

Weigh your choices and err on the side of recovery.
