Hardware Compression

[kenjithl]

Hi All,

I am using Arcserve 11.1 and Dell PowerVault 110T SDLT 320 Tape Drive.

Recently I have to insert extra tape to complete the backup.
So I run a test backup with hardware compression on a 2GB data, and the result I get is:-
Total Size (Disk)............ 2000 MB
Total Size (Media)........... 2000 MB

With the same data, I disable the hardware compression. The result i got is:-
Total Size (Disk)............ 2000 MB
Total Size (Media)........... 1100 MB

So, wonder is there anything wrong with my hardware compression? Or is there some setting I miss out that could cause the Hardware compression deos not compress the data.

Thanks

The application controls compression. So after you disable the compression ARCserve just enables it again.

If the exact same data was used both time the results should have been the same each time.
