rgaskell Posted November 11, 2009 Report Share Posted November 11, 2009 Hi all, bit of a problem that has been puzzling me. Scenario We run Retrospect server backing up network clients to several sets of removable hdds utilising several scripts. We have 4 sets of media (Backup Set 1 - 4) & each set of media comprises 6 disks. We lost several disk through attrition and utilised the working disks to supplement what is now 4 working sets of media with 5 hhds I've bought a new set of 5 hdds, created a new backup set (Backup Set 5) and corresponding script based on the other backup scripts. Problem I plugin the first hdd of the new media, start Backup Set 5 and off Retrospect goes, backing up clients to 1-Backup Set 5. After the first clients are backed up I plugin the next disk. Once Retrospect determines it has a new hdd inserted it renames the fresh disk 2-Backup Set 4, ignores 1-Backup Set 5 and starts writing to 2-Backup Set 4 I erased the media using the Retropect option to do so and called it 2-Backup Set 5 but as soon as I kick off the server again it renames it. I thought maybe I've missed something here and hopefully someone might offer some pointers! Quote Link to comment Share on other sites More sharing options...
Lennart_T Posted November 11, 2009 Report Share Posted November 11, 2009 The backup server has 5 backup sets as its destination. If all are set to active for the time period in question, you have NO idea which one Retrospect selects. So if you temporarily removes sets 1-4 as destination, you have only one backup set as destination. Quote Link to comment Share on other sites More sharing options...
rgaskell Posted November 11, 2009 Author Report Share Posted November 11, 2009 Thanks for taking the time to answer Lennart, I think I see. Basically I need to disable the other destinations until I have filled Backup Set 5. At that point I can then move to the next set in the rotation (Backup Set 1) and re-enable all destinations, correct? Quote Link to comment Share on other sites More sharing options...
twickland Posted November 11, 2009 Report Share Posted November 11, 2009 There is another solution that we use. The reason Retrospect is creating member "2-Backup Set 4" is because member "1-Backup Set 4" is full. Whenever a backup server script is running, Retrospect will try to rotate among the various destination backup sets and, having written to Backup Set 5 for awhile, it will prefer to write to another available backup set. One solution is to create member "2-Backup Set 4" yourself by running an immediate backup of a few files to Backup Set 4. Then remove member "2-Backup Set 4." The next time, Retrospect should create and write to "2-Backup Set 5" when there is blank media available (unless there is another backup set that is also waiting for a new member). Be aware that, under a backup server script, Retrospect will always choose on its own to name the next backup set member if there is more than one destination backup set awaiting a new member. If you wish to control exactly which backup set Retrospect is using at a given time, you may prefer to use a standard backup script rather than a backup server script.

That way you don't even have to disable the destinations. Quote Link to comment Share on other sites More sharing options...
rgaskell Posted November 12, 2009 Author Report Share Posted November 12, 2009 Excellent, many thanks for the tips both I've got this sorted now Quote Link to comment Share on other sites More sharing options...
Lennart_T Posted November 12, 2009 Report Share Posted November 12, 2009 Thanks for posting back and let us know our proposed solution worked. (Some don't post back and we have no idea what happened.) Quote Link to comment Share on other sites More sharing options...
