GerryRigney Posted February 4, 2008 Report Share Posted February 4, 2008 Hi All We are suddenly having a problem with one of our backups. Running Retrospect 5.15 on a win2k server. Every night the server backs up 5 volumes (incremental backup). Its gets as far as counting(?) the files its needs to copy for the 1st volume and then stops. The error in the operations log is "Not enough application memory". The machine has 2.5GB of RAM and plenty of free space on the OS drive. At the last attempt, there were 8814 files needed to backup (9.8GB) As a test I tried to backup the whole volume to a new set, again it counted all the files but stopped with the same error in the log (335616 files this time 339.4GB). As another test I tried to backup one of the other volumes on the server to a test set and it began backing up successfully. I have also restarted the server in case that was it. Can anyone shed some light? There seems to be very little reports of this error in the forums. Appreciate any assistance, if you need any more info please let me know.

Mayoff Posted February 4, 2008 Report Share Posted February 4, 2008 This version has very poor memory management. You should upgrade to a current version of Retrospect. You are using one of the first versions we ever released. Quote Link to comment Share on other sites More sharing options...
GerryRigney Posted February 4, 2008 Author Report Share Posted February 4, 2008 Well its worked fine for us up till now, I don't think there's any shortage of memory as Retrospect doesn't seem to be using too much in task manager. Anyone got any other ideas? Quote Link to comment Share on other sites More sharing options...
GerryRigney Posted February 4, 2008 Author Report Share Posted February 4, 2008 If we do upgrade to 7.5, will our existing backup sets still work with it or will we have to start them all over again? Thanks Quote Link to comment Share on other sites More sharing options...
Mayoff Posted February 4, 2008 Report Share Posted February 4, 2008 I believe they will work, but to take advantage of new features, like better performance and greater backup set capacity, you should create new sets. You can always download a trial version and see how it goes. Quote Link to comment Share on other sites More sharing options...
GerryRigney Posted February 4, 2008 Author Report Share Posted February 4, 2008 Hi Mayoff I am just downloading the trial now. Problem is the tapes are 40/80 DLTs and there is over 400GB to be backed up so if I have to start all the sets over (5 sets, mon, tue, wed, etc.) it will take weeks before I have them all set up. Also, if we upgrade and are unable to recover files from the old sets it will be a disaster! Any idea if this will work? Thanks again Gerry Quote Link to comment Share on other sites More sharing options...
Mayoff Posted February 4, 2008 Report Share Posted February 4, 2008 Reading old backup data should not be a problem to the best of my knowledge. We don't hear about too many people still running 5.15, so it is hard to remember. Quote Link to comment Share on other sites More sharing options...
rhwalker Posted February 4, 2008 Report Share Posted February 4, 2008 A possible issue might be if you decide to revert back. 5.15 won't be able to read backup sets written by 7.5 with new features. I'd suggest testing with different backup sets. Quote Link to comment Share on other sites More sharing options...
fastrecovery Posted February 26, 2008 Report Share Posted February 26, 2008 I got this problem the first time 20/02/08. The Catalog file went corrupt. Recreation of Catalog file failed. 3 weeks of backups were lost. I am not sure if the problem is on the server to be backup up or the server where Retrospect is running. Problem returned today. This time Catalog file is ok. Added Microsoft Security pathes, IE7, Silverlight, 21/02/08, i.e. one day after the first time the problem appeared. McAfee patch 16 is not recommended for servers, and is not installed on this server, only patch 15. And On-access scanner is not running. Could it the large number of files for this partition: over 6,000,000 be a problem? Any hint would be appreciated. Quote Link to comment Share on other sites More sharing options...
Mayoff Posted February 26, 2008 Report Share Posted February 26, 2008 Retrospect 7.5 has only been officially tested with volumes in the 4 million file range. Make sure you have at least 2 GB of physical RAM and 15 GB of free disk space on the C drive. Quote Link to comment Share on other sites More sharing options...
fastrecovery Posted July 24, 2009 Report Share Posted July 24, 2009 What are the limits for Retrospect 7.6. I have 2 GB memory, only 13,5 GB free space on C:-drive. I have 6,000,000 files on subvolume. I experience problems, slow behaviour at restore, or fail to display the contents of the volume when I want to select files and folders to restore. :tongue2: Quote Link to comment Share on other sites More sharing options...
Mayoff Posted July 24, 2009 Report Share Posted July 24, 2009 Retrospect has been tested with up to 4 million files in a single volume. 1) You should probably have at least 3 gigs of RAM. Retrospect is a 32 bit app so it won't use more then 2 GB for itself. 2) Retrospect will cache a lot of data to the hard disk when memory is low. I would suggest you have at least 20 to 30 GB of free space on the C: disk when working with a high number of files. Quote Link to comment Share on other sites More sharing options...
