Jonathan Posted March 21, 2002 Report Share Posted March 21, 2002 I'm using Retrospect 4.3 with a VXA-1 tape drive on a MAC 9600 running OS 9.1. When I Configure>Create New backup set in Retrospect and leave on hardware compression (default) the software compression is still available under Backup>Options and not grayed out as it says it will be in the dialog box. Is that ok or does this indicate a probelm? Checking the Backup Set Configure>Summary in Retrospect does report that Hardware Compression is enabled. (This is all without encryption.)

IrenaS Posted March 27, 2002 Report Share Posted March 27, 2002 That's fine. That option won't be grayed out, but if the drive you're backing up to has hardware compression, software compression is automatically disabled. Link to comment Share on other sites More sharing options...
chrisa Posted July 11, 2002 Report Share Posted July 11, 2002 That's funny, I thought it did grey out when hardware compression was active. We definately used to get the compressed capacity on our SDX-35C (35/70gig) tapes with our CY-8000 AIT drive. One day I noticed that a fresh 60gig drive backup was suddenly asking for a tape halfway through and I checked the settings. I thought it had been greyed-out before and was now showing available. Hardware compression used to work great and I figured the software compression option now not being greyed-out was a sign that hardware compression had somehow been deactivated? OK....maybe I was hallucinating.... ;> But I'm still only getting uncompressed capacity from tapes now and I'm stumped. I'm not getting media or write errors, but the only thing Cybernetics tech support could think of was cleaning the tape drive. I'll give that a try. Is there anything else I should be looking for? I mean, I know all the stuff about why tapes might not operate to written capacity, but is there any other setting that needs to be on in Retrospect to let the CY-8000 do it's hardware-compression thing? Thanks. Chris Link to comment Share on other sites More sharing options...
AmyJ Posted July 12, 2002 Report Share Posted July 12, 2002 For more information on tape capacity and compression, please see the following Knowlegebase articles: Tape Capacity FAQ: www.dantz.com/index.php3?SCREEN=kbase&ACTION=KBASE&id=27365 Why are my tapes filling up sooner then expected? www.dantz.com/index.php3?SCREEN=kbase&ACTION=KBASE&id=26912 Link to comment Share on other sites More sharing options...
chrisa Posted July 24, 2002 Report Share Posted July 24, 2002 these links go to the wrong articles!? but yes, i've seen the faq stuff and i'm hoping a cleaning tape will help. just seems bizarre as it was a sudden change (not slow deterioration) chris Link to comment Share on other sites More sharing options...
