Backup compression questions.


Recommended Posts

I have two questions about Retrospect compression behaviour.

 

1. I have an AIT2 tape that has built-in hardware compression and Retrospect can do software compression.

Which will compress better ?

The built-in hardware compression included in the tape unit or the software compression algorithm from Retrospect ?

 

2. If I compress a backup stored in a disk with Retrospect software compression and after i copy the backup to a tape. Retrospect will store a a compressed copy in the tape or it will uncompressed the files to store to tape ?

Use the hardware compression. It always compresses in real time. Software compression is a performance hit.

(I think software compression isn't an option when hardware compression is used.)

 

I think the files will be sent uncompressed to the tape drive and re-compressed there.
