Daylight saving times reset incremental backup after clock changed to sync with Microsoft Time Servers
this is happing to me twice a year and i musy solve it.
We are working with BE 2010 R3 SP2 on Win Server 2008 R2 SP1. we back up the local machine only.
Our workflow is based on a one time full backup, and a daily incremantel backup. we are using the ADBO in order to have the True Image Restore option (we are backing up to LTO tape)
we use a policy that have one time Full backup (reset Archive Bit) and a daily incremantel backup (reset Archive bit)
In both backups in the policy we are checking "Collect additinal information for True Image Restore".
Twice a year, after the Daylight saving time is chnaging on Windows, and the time on the machine is changing to be synced with Microsot Time Servers, the daily incremantal start backing ip ALL the data all over again has it thinks that something has chnagein the files.
The archive bit has not been chnaged on the data, it is reseted on all the files - but from some reason, maybe because True Image Restore option use a more complex method before strating the backup, ALL the data is being backup again.
1. as for now, i got a 20TB folder that is already benn backed up, but BE wants to back it up again, i can't exlude the folder in the selection list as more files should get into that folder in the future, how can i force BE NOT to backup the files that are already been backed up? the Archive bit is alreaty reseted and its still wants to backup the same data again.
2. how can i preven it in the future when the clock will be chnaging again?
