Exceeded the [In-File Delta] -> [Maximum no. of Delta] setting


Exceeded the [In-File Delta] -> [Maximum no. of Delta] setting. File “XXXX” is being backed up in its entirety because more than 100 delta files have been generated already.


  • This is a large file that has hit the configured delta chain limit, so the full file is being uploaded again and a new chain will be started.


The following options are available:

  1. Let the backup complete by uploading the full files
  2. OR reseed the backup set in question
  3. OR reduce the backup schedule to run less frequently, therefore generating fewer deltas over time
  4. OR enable delta merge, however you can only have a rolling window retention and not an advanced retention policy with delta merge enabled.
