A full backup takes 3 hours. The test of that backup takes 8 hrs. Something is amiss. I read the forums and have done all the recommended fixes: all Fbackup .exe's and the network destination drive are excluded in the virus scanner (MS Security Essentials), the minimum set of source files to back-up are selected (no windows or system files), etc.


We're running Win 7 64 bit, FBackup 4.6.253, network backup to a Seagate Central Axis via wired network.


Any more suggestions?

Hi,


What is the read speed from the destination device?

If you manually copy a large file to destination and then you copy it back, is the copy time the same for both cases?

The write spped of a 751Mb file was averaging about 10.5 Mb/s, 1m 15 s total time. The read for same file copyed back to PC was averaging 11.5 Mb/s, 1m 05s total time.

Hi,


Is the time difference the same for the next backup updates?

The timing was the same on the next backup too. Would like a log file?

P.S. We also have esentially an identical backup set-up on a Vista machine on the same network and back-up server. The backup takes about 3 hours and the test less than one.

Hi,


As the backup jobs are configured the same way (as you told us), is there any difference how these two computers access the destination drive?

Is one computer behind a router?

There is one switch that the two computers and the backup server are connected to. Both computers have the destination called out the same way, e.g \\Mca-05abb7\jiloa\My Backup\Charmed2010\Weekly Backup\. Each has it's own file directory. The weekly full backup ran again yesterday with the same results. About three hours for the backup and about 8 for testing. The daily mirror backup takes about 30 minutes and testing takes about 30 minutes. Could there be something to do with the compression of the weekly?

Hi,


You cannot compare a Full backup (which is zip compressed and include all files) and a Mirror (which is not zipped and include only new and modified files).

O.K. But why does the full backup on the Vista 32 machine test so quickly while the full backup on the Win 7 64 machine test so slowly? What else can we try to solve this long test issue?
