No error as far as I know, I originally used the W7 one and didnt mind it but it took a couple hours just to backup about 50gbs of data.
Since a couple days ago I decided to try out some others. I used the one by EaseUS and another that I dont remeber off the top of my head. The last one I tried was Aomei backupper, I like it so far because it compresses unlike the other two I tried before.
Edit: I just checked the event viewer logs and it shows that VSS has two errors within 24 time period, only problem is I have no idea what from exactly other than it had to of been from when I was doing a backup with Aomei backupper.
Ok the error says: Volume Shadow Copy Service error: Unexpected error querying for the IVssWriterCallback interface. hr = 0x80070005, Access is denied.
. This is often caused by incorrect security settings in either the writer or requestor process.
Could it possibly be because of Cryptoprevent? I do use it and havent whitelisted anything in a while, otherwise im unsure what security settings its refering to unless its avast! causing the error.
You can go into CryptoPrevent and one of the pulled down menus shows you the blocked logs.
However, think it only logs items blocked since last boot.....so if you have not rebooted you can try.
My guess......and only a guess.....is that this is not CryptoPrevent but a VSS issue based on other items in your system and/or Avast in concert with those system issues/items......but you'll need to do some testing to really isolate the issue or interaction issue/conflict.
Some first easy tests......
Go into CryptoPrevent and UNDO the changes, reboot, and retry and see if works ?
Go offline, disable Avast and try a backup......see if it has any effect ?
Here is thread on IVssWriterCallback error.

Remember, doing just a "uninstall" out of Windows on these A/V programs does not remove all remnants.....and they DO cause issues/conflicts.
Take some time and make sure your system is truly clean of old A/V programs:

Do some googling on each of the packages and see what is shown to "remove".....perhaps some manual deletes of leftover folders if they have been uninstalled.
Then, do a Clean Uninstall & Re-Install on Avast How-To:

If none of the above work here is another potential issue/solution with VSS that you can investigate.

http://www.macrium.com/reflectfree.aspxIt compresses at different levels if you want.......easy to use....I personally have recovered to new HDDs many times and works well.
It is a very reputable package.....always kept current.....and handles VSS very nicely.
