Files not being matched from previous session! (doing Normal backup)


Recommended Posts

I am using Retrospect 5.0.238, OS X Server 10.2.8 on Xserve, to Sony AIT-2 autoloader.

 

 

 

On 8 April I did a local backup of directories on the Xserve, which amounted to 152.6 GB. Today (24 April) I attempt a Normal backup of the same Sources group and find that the backup will be 261.4 GB, or 99% (!!!) of 267.5 GB total. This is nuts because most files haven't been touched and it is an inconvenience to be forced to do a Recycle backup at this point.

 

 

 

It looks like Retrospect is not matching properly between sessions. Any clues?

Did you change the time zone perchance? Dantz continues to insist that this should cause files to be backed up again because the creation/modification times change, though under OS X this information is actually stored as UTC (without timezone interpretation) so it should be trivially detectable. I have to leave my timezone alone as I move back and forth to avoid this problem, sigh.

No.

 

I thought it might be a Daylight Saving transition (our machines are network time synced) BUT not possible:

 

Melbourne, Victoria, Australia ( http://www.timeanddate.com/worldclock/city.html?n=152 )

DST ended on Sunday, March 28, 2004, at 3:00 AM local daylight time

DST starts on Sunday, October 31, 2004, at 2:00 AM local standard time

 

I have investigated the time issues with Retrospect before. Mac filesystem time stamps have always been absolute, so there should never have been problems AFAIK.

What do you see when you get info on a single file in your Backup Set and its counterpart file on the hard drive?

 

Reports>Contents> choose a Backup Set and Snapshot > Select a file>Command+i

 

Then

 

Immediate>Backup>Preview>Select corrosponding file>Command+i

(your source should probably be a defined subvolume here to limit scan time)

 

What differences do you see between the two files?
