What does the backup escalation feature for fast compression do in the backup wizard?

This option causes Litespeed to issue a full backup, if one of the following problems is discovered in the current backup set:

• The full backup is missing
• A differential backup is missing from the backup set (excluded backups automatically removed after the specified retention period).
• LSN verification fails in the backup set.
• Verify operation fails on full or differential backup.

If a problem is detected and a full backup is created through escalation, an error will be returned.

If a support case needs to be created make sure that the specific error message is listed in your support case along with details of how the error came about.
