Backup content and exclusion rules

Before the backup, make a clear list of what really needs to be retained, and then decide which directories and files do not enter this backup.

Typical retention requirements include:

• Business Master Data Directory
• Profiles and running configurations
• Supporting files that must be relied upon when restoring
• Required Run Logs or Audit Logs

Typical ones that are not backed up include:

• Temp Directory
• Cache directory
• Build Product
• Data with a separate backup link already exists
• Regeneratable intermediate files

If the file is missing after recovery, first check whether it is not included in the backup, or filtered by the exclusion rule.
If the backup volume is obviously large, first check whether the log directory, cache directory or other content that does not need to be retained for a long time is brought in.
