hinzinho Posted May 9, 2006 Report Share Posted May 9, 2006 Hi I'm using a 80/160GB tape drive. The files I'm trying to backup are photos, roughly around 60GB of photos. If I understanding this correctly, it should fit to a single tape, but Retrospect is asking for the second tape. The first tape contains 57GB The second tape contains 2.7GB Why does it need another tape?? Thanks! Link to comment Share on other sites More sharing options...
nekr0phage Posted May 9, 2006 Report Share Posted May 9, 2006 Hi Hin, What operating system are you working with? Which version of Retrospect? What kind of tape drive and how is it connected to the system? Are you using hardware compression or software compression? Link to comment Share on other sites More sharing options...
Lennart_T Posted May 10, 2006 Report Share Posted May 10, 2006 Photos doesn't lend themselves to good compression. In the case of already compressed files (such as JPG or LZW compressed TIFFs) you can't compress them more at all. If you are backing up a "slow" disk or a disk over the network, the tape drive has to stop and wait for more data, possibly waste some space on the tape in the process.

hinzinho Posted May 10, 2006 Author Report Share Posted May 10, 2006 I guess a little bit more info should help huh?? OS: Windows 2000 Server Retrospect: 6.5 Server Tape drive: VXA-2 80/160 external tape drive connected via SCSI I know for sure it's not using software compression. If I click on the backup sets and view properties > under options, it has Hardware compression. Fast catalog file rebuild. How can I disable the hardware compression?? Thanks!

Lennart_T Posted May 11, 2006 Report Share Posted May 11, 2006 Disabling hardware compression is not the answer. There is no penalty in any situation to have it enabled. Are you backing up clients? Or a local backup? Link to comment Share on other sites More sharing options...

OK, if you watch the backup running (on the first tape), does the tape drive stop and start a lot? Link to comment Share on other sites More sharing options...
