The following best practices are recommended:

• If a volume contains many hard links or has SIS (Single Instance Storage) enabled, you should not select the Use the Microsoft Change Journal if available option. When the modification of these files is detected, Backup Exec reverts to performing backups without using the Change Journal, and backups could require more time.

• You should avoid creating many incremental backups between full backups. Symantec recommends that you run weekly full backups.
