I use this great UrBackup app.
The only problem I have now is that Outlook PST files are taking a lot of space.
For example if I make an incremental backup all PST files are copied once again even if I have no new mail. I tried “Block differences - hashed” transfer mode with the same result. I noticed that UrBackup does not copy entire PST file but with copied part the program rebuild PST file on storage device and used space increase with full PST size (as FreeNas also display) .
Maybe this is normal but the storage space decrease rapidly when you have users with 10-40 GB PST files.
Is there an option to use backup interval for PST files different from other files backup interval? For example: 1 hour for files and 1day for pst files backup interval
Please advice me to find the best approach for PST problem.
I use UrBackup server 2.0.36 (installed on FreeNas 9.10) and UrBackup Client 2.0.34
