The backup type is not known.

This value indicates an application error.

Full1

Full backup: all files, regardless of whether they have been marked as backed up or not, are saved. This is the default backup type and schema, and all writers support it.

Each file's backup history will be updated to reflect that it was backed up.

Incremental2

Incremental backup: files created or changed since the last full or incremental backup are saved. Files are marked as having been backed up.

A requester can implement this sort of backup on a particular writer only if it supports the Incremental schema.

If a requester's backup type is Incremental and a particular writer's backup schema does not support that sort of backup, the requester will always perform a full (Full) backup on that writer's data.

Differential3

Differential backup: files created or changed since the last full backup are saved. Files are not marked as having been backed up.

A requester can implement this sort of backup on a particular writer only if it supports the Differential schema.

If a requester's backup type is Differential and a particular writer's backup schema does not support that sort of backup, the requester will always perform a full (Full) backup on that writer's data.

Log4

The log file of a writer is to participate in backup or restore operations.

A requester can implement this sort of backup on a particular writer only if it supports the Log schema.

If a requester's backup type is Log and a particular writer's backup schema does not support that sort of backup, the requester will always perform a full (Full) backup on that writer's data.

Copy5

Files on disk will be copied to a backup medium regardless of the state of each file's backup history, and the backup history will not be updated.

A requester can implement this sort of backup on a particular writer only if it supports the Copy schema.

If a requester's backup type is Copy and a particular writer's backup schema does not support that sort of backup, the requester will always perform a full (Full) backup on that writer's data.

Other6Backup type that is not full, copy, log, incremental, or differential.
