taalfaro Posted August 10, 2004 Report Share Posted August 10, 2004 My backups are asking for a second tape in order to complete. When I check, Retrospect indicates I am 4.9GB over the tape limit. Here's the problem. When I calculate everything I am backing up, there should be no reason for it to be asking for a second tape. When I run the log, I am seeing a big size discrepancy on my volumes. For example, one volume is 2.78GB when I look at it in Get Info. Retrospect is reporting it is 32.4GB. This type of thing continues with all my other volumes. Has anyone seen this? What recommendations can anyone give me. Thanks. Quote Link to comment Share on other sites More sharing options...
plaqueguy Posted August 11, 2004 Report Share Posted August 11, 2004 I am having a similar problem. Retrospect is also asking me for an additional tape when executing a scripted backup to my AIT tape drive, but I do not have the discrepancy in the log that you are seeing. Please let me know if your hear anything further about this problem. Thank you. Quote Link to comment Share on other sites More sharing options...
natew Posted August 17, 2004 Report Share Posted August 17, 2004 Hi Retrospect writes to the physical end of the media. Its not going to ask for another tape unless it is truly full or there was a media error of some kind. What is the native capacity for the tapes you are using?

natew Posted August 23, 2004 Report Share Posted August 23, 2004 Hi There are a lot of factors that can affect the amount of data on a tape. How is the tape drive connected to your machine? If it is SCSI, what SCSI card and driver version are you using? How fast is the computer running the backup. If the machine is too slow the tape can outrun the data causing wasted space on the tape.
