tcat Posted February 6, 2003 Report Share Posted February 6, 2003 our backups used to take only one Dat 12/24 G tape. We ran these backups on one tape for two weeks. Now we decided to run a daily backup. Each day to a seperate tape (Mon thru fri). All of a sudden we are using two tapes for each daily backup. The Sony SDT-9000/PB device has the compression jumber enabled. I have also tried using the Software compression feature on Retrospect. [color:red]how can I tell if the data is being compressed?[/color] Link to comment Share on other sites More sharing options...
AmyJ Posted February 6, 2003 Report Share Posted February 6, 2003 If you are using software compression - performance data will be listed in the log (percentages). If you're using hardware compression, you can see how much data is fitting on each member by going to Configure > Backup Sets > Properties. The members tab will give you the total amount of data stored per member. Because compression is performed by the hardware, the Retrospect log cannot generate percentage data.

tcat Posted February 6, 2003 Author Report Share Posted February 6, 2003 it's telling me that I used 21.5 G and I had 22.7 G available on a 12/24 G DAT tape... .............things that make you say, "...hmmmmmm....?" I will configure the script so it doesn't save cache files...this will be especially important in the roaming profiles which can get quite large. I'm only putting 1.7 G on the second tape...if I can squeeze that back onto the first tape and not use a second tape, I will be a happy camper. Would it be a good idea to compress the catalogue...?
