speleo14 Posted April 22, 2014 Report Share Posted April 22, 2014 Hi there Simply can't find out what is wrong here... Retrospect 10.5.0 on Mac 10.6.8, Quantum Scalar i40 Tape Library; Client 10.0.0 (174) on Mac 10.8.2. I'm backing up an external Hard Drive with about 2TB of data. If I let the backup script run on schedule, it always tries to back up everything even after the initial full backup, i.e. the entire 2 TB (it tries because I then of course stop it). If I start the same script manually, it seems to do an incremental backup, that is, it will only back up some GB (I assume that these are the files that were changed since the last backup, but haven't checked). The same script used to work fine until a few weeks ago when this started happening. I created a new script with the same settings - same. I reinstalled the Retrospect client - same. Any ideas?

ggirao Posted April 22, 2014 Report Share Posted April 22, 2014 Probably that happens when you propagate permissions on source. You can untick the option "use attribute modification date when matching" Quote Link to comment Share on other sites More sharing options...
speleo14 Posted April 22, 2014 Author Report Share Posted April 22, 2014 I'll give this a try - though it doesn't explain why this only happens when a script is run automatically on schedule and not when I start it manually? Quote Link to comment Share on other sites More sharing options...
twickland Posted April 22, 2014 Report Share Posted April 22, 2014 I'll give this a try - though it doesn't explain why this only happens when a script is run automatically on schedule and not when I start it manually? Every scheduled execution has a specified media action. Have you confirmed that each scheduler specifies "no media action?" If this is so, try changing the media actions to something else, saving the script changes, changing back to "no media action," and saving the changes again. 1 Quote Link to comment Share on other sites More sharing options...
speleo14 Posted April 23, 2014 Author Report Share Posted April 23, 2014 No, the trick with the attribute modification date didn't help. Still wants to back up everything. I have also checked the media set settings, and they are definitely on "no media action". Changed it to something else and back again to no avail. It seems that this behavior only happens on that one client and with one specific volume of that client. I added another client to that script for a test - works fine. Added another source on the same client, but on a different external drive - works fine. Added a new folder on the volume that shows the weird behavior - works fine... I guess I'll give it another (about the third) try and start a completely new script and completely new media set and do another full backup that will be taking 3 days (slow network). Thanks for trying to help. Edit: Just checked the volume with Disk Utility and it needs to be repaired. Well, that's new (checked that before, and it was fine)... but at least this would make sense.

speleo14 Posted April 30, 2014 Author Report Share Posted April 30, 2014 I think I now finally found the culprit, and no, it was not the volume, but Instant Scan. This "backiing up far too much" started on a second client (backed up 700'000 files, 1.5 TB, and there's no way that many files could have changed, especially not duringe the weekend...). I turned off InstantScan on those two clients, and so far, backups are back to normal. Hope it stays this way. Anybody else having / had similar problems with InstantScan?
