I was trying out the fbackup4 on my windows server 2008. I did a "mirror" backup from my E drive to my NAS (mapped as Z drive). The backup completed with no errors. However, I found that for some folders that have files with *.BAK were empty.
I tried backup the *.BAK files and same thing happened.
From the log, it shows the number of folders but the files was zero.
I did another test and found the following:
It can only backup new files that have never been bkup before.
If I had backup the folders\files & deleted them at the destination, I will not be able to backup the same folders\files again.
I am not sure if my observation is correct.
