Thanks for your reply, this seemed a nice solution However, here is what had happened with our very very badboys network's administrators : a) They restored 159Gb of data backed up on monday (slow, need some disk storage, but it was available) b) they used rsync as follow : rsync -avr x y c) today everybody was happy when seeing they had LOST three days of work and since the tape was running to restore ... no backup until now So, now I have some more questions : 1) Using a tape is slow, is it possible to use a disk storage as backup device with bacula ?? 2) if 1) is possible, can we use concurrent accesses to the catalog in order being able to restore some data , while we are backing up other ones Regards S.Ancelot -- Simplify data backup and recovery for your virtual environment with vRanger.

Re: [Bacula-users] diff between last backup and actual filesystem content
So, now I have some more questions : 1) Using a tape is slow, What kind of tape do you have? LTO4 and above net over 100MB/s. is it possible to use a disk storage as backup device with bacula ?? Yes. 2) if 1) is possible, can we use concurrent accesses to the catalog in order being able to restore some data , while we are backing up other ones Yes that will work with tape or disk.

I had seen more powerful backups system in the past, are you sure there are no other ways You could also do a verify level disktocatalog. However I believe that would only work if the last backup you ran on client was the backup you want to compare. That is unless bacula fixed this bug.
