137491BFCBC98DE1E040000A2A666149 posted a topic in Retrospect 9 or higher for MacintoshFor clarity, I'll name the two following media set references "Media Set 1 Verify" and "Media Set 2 Backup": I ran a routine Verify session on my LTO 4 tape media set "Media Set 1 Verify." Prior to this verification, each of the 8 tapes in the media set reported an estimated compressed capacity of 1.6TBs and had used between 850GBs and 990GBs per tape. All good for this LTO 4 media…so far. After the verification, which automatically picked and read each tape in the set during the process, the reported estimated compressed capacity now shows as 12.8TBs per tape. YIKES! I know Retrospect will always use each tape until full or to failure but I'm REALLY missing the ancient Retrospect 6 feature of being able to assign/override estimated capacity. Anybody got any ideas on how to get the estimated capacity back to 'normal?' I'm going to rebuild this catalog as 'Fast Catalog Rebuild' is selected for all my tape media sets. I'll report back once complete. A second issue which presented itself during this media verification: While "Media Set 1 Verify" was running, so was "Media Set 2 Backup," a different LTO 4 media set in this same T80 Library. Since upgrading to Retrospect 10.5.0, I've had to manually move an erased tape into an available drive when Retrospect showed the "Media Needed" icon and "Waiting for Media" message for both media sets on this Library. However, all of a sudden "Media Set 2 Backup" started properly picking the next erased media as each tape filled. It continued to do so until "Media Set 1 Verify" was complete. Then it reverted to it's previous 'manual tape insertion' requirement when the current tape was filled. Note that all tapes in this Library are LTO 4, are either already assigned/named for a given media set or are 'erased' and ready for use by any media set. I'm checking for drive and library firmware updates now to ensure they are current. The fun continues. -Steven
Rustcity posted a topic in Retrospect 6: Desktop, Workgroup and Server for Mac OS XI have got a little problem with the installation. We switched from a Tandberg Autoloader SCSI (LTO3) to a Tandberg Autoloader SAS (LTO4). On a Mac Pro (OSX Server 10.6.8) I changed the PCIe-Card (from SCSI to SAS). Then I installed the driver. I can see the Card and the loader in the system profiler but I don't see the Autoloader in Retrospect. I couldn't find anything in the manual. The Backup worked pretty well with the SCSI. (but slow) Any suggestions? Do i have to update the version of Retrospect? Thanks.
Jeffops posted a topic in ProfessionalI've got a backup set on LTO4. When I check the stats on the members the last one used shows a size of 2162 GB which is impossible for LTO4. The next member is new and empty which makes no sense. I considered recreating the catalog file, but I am concerned that might screw things up more. Any suggestions?
