A Full Backup Runs Instead Of Synthetic (codes 1519-1521)

Last Updated 2020/9/16


A backup plan terminates with the following warnings:

  • Encryption settings changed. Encryption settings were changed. A full backup was executed
  • Compression settings changed. Compression settings were changed. A full backup was executed.


These warnings occur due to restrictions of data part structure on backup storage. If encryption or compression settings are changed, so changes the data structure and existing data on backup storage cannot be used for an in-cloud data copy. A real full backup starts instead of synthetic backup.


These warnings do not imply any solution and are created to aware of the full backup execution since it might take much more time than synthetic full backup of the same data amount.
