How Encryption and Compression Works with Deduplication

Compression and encryption are not supported when used with deduplication devices. However, in staging jobs, compression and encryption are not supported in the Staging phase, but are supported in the Migration Phase only when the final destination specified is a non-deduplication device. The following table lists the options available depending on the device specified.

Note: For more information about Arcserve Backup encryption and compression options, including limitations and considerations, see Backup Manager Encryption/Compression Options.

Staging Location	Final Destination	Compression/Encryption Options Available
Non-deduplication device	Non-deduplication device	All options are available.
Non-deduplication device	Deduplication device	Encrypt Data options not allowed Compress Data options not allowed
Deduplication device	Non-deduplication device	Encrypt Data options: "at Backup Server During Migration" Compress Data options: "at Backup Server" Note: Compression must be specified with the encryption option "at Backup Server During Migration."
Deduplication device	Deduplication device	Encrypt Data options are not allowed. Compress Data options are not allowed. You can still select them, but an error message will appear.
