Differential backups taking 12 hours to complete

Thread needs solution

I installed ATI2016 on my Windows 7 machine in mid-January, and it is scheduled to run long after I stop using the computer.  All was well for several weeks.  Differential backups usually complete in 30 minutes - 1-1/2 hours and are always less than 4G in size.  The situation has been intermittent, but now I've had 2 in a row.  Acronis deletes backup sets after 4 have been created.  That is working fine.

I'm also running the backup program that came with my Western Digital external drive.  I run it 3 hours before the Acronis start time.  Since my problem has been intermittent, I don't think the WD backup is conflicting with Acronis, although there may be overlap.

I check processes in Task Manager and can't identify the program running, just Helper, Monitor, and perhaps others, but none seem to be the Acronis .exe process.  In addition, Task Manager shows no applications running during the backup time frame.

Support has expired.  I hope a forum member can help me with this.

Kfuser,

If possible, could you disable the WD backup software and let the backups run to see if that doesn help at all.  Most backup applications borrow from Window VSS to lock a snapshot of the system and build the image from that.  It is possible that the two are conflicting at times.

Any chance the computer is sleeping or hibernating when the job is supposed to be running?

What about power managment options?  Perhaps the system is turning off the local disk or backup disk because it is set that way.  In your power management scheme, you'll want to see if that is the case.   Also, your local system USB hub may be set to power save as well which could be dropping the external drive at times.  Take a look at this post for some ideas about power managment to see if any of those apply and may be useful:

There are times where backup scripts do get corrupted.  You could try creating a new backup set (keep the old one too but disable it if you want) and see if it behaves better.  A few of us have also had problems with the database being an issue.  There is a word-a-round of disabling the Acronis services (4 of them), renaming,  "C:\ProgramData\Acronis\TrueImageHome\Database" to "C:\ProgramData\Acronis\TrueImageHome\Database.old" or something like that, starting the acronis services and running the backup job again.  This should keep all of your settings and backups in place, but if the database was corrupted, it will force Acronis to make a new one and hopefully resolve the issue (perhaps do that as a last resort though - I have done this a few times in the past with no apparent issues as a result, but you are manually fiddling with the application doing this).
