Larger Backup-size then Diskspace???

[BeArt]

Hello there,

Since this month I am experiencing a very (?) weird problem....
On a server there seems to be more backup-data then disk-space, and now I am wondering if it is so that compressed files are put on tape uncompressed?
And if thats true, than I am wondering hot I can put this compressed files compressed on tape? Situation now is >40Gig. while the DiskSpace is 32Gig. kind a odd I suppose...

If someone please can help me out? thanks in advance.

Greetz,
Bart

Sounds like your files are all compressed. They are probably being uncompressed as ARCserve reads them into the backup. Is your tape device using hardware compression? The algorithms are probably different resulting in different compression ratios. Also there's overhead involved on the tape - writing blocking headers etc...

Hi mspope

Thanx for your input....
Well I am not using hardware compression...

Still it would be possible to move compressed data 2 a tapeunit? or do I have to compress like C: to get the data compressed to tape?

Thanxs in advantage!
