0x80070005 Can't Backup my computer, What's wrong now?

Mar 27, 2013 6:33AM PDT

I have tried to backup my computer to a USB external hard drive. Have done it in the past, but now get the 0x80070005 error. Looked at the files actually saved and originally there were over 25 different compressed files. Now it gets to about 11 files and quits with a failure message?? Help please

Try one of these

I suggest you get away from the Windows backup program and get yourself a good commercial backup program. This forum is fraught with problem reports for the Windows one. I know I was very unimpressed when I tried it. Three I'm familiar with and like are Norton Ghost (which I've been using for 8 years without the 1st problem), Easeus Todo Backup Free, which you can download from and Memeo which has a 30 day free trial and you can buy it for $29.99 - you can download it from . You can get Ghost for next to nothing (like I did) if you watch the sales.
The March 2012 issue of PC World was very high on the FREE program from Easeus, and I've been testing it lately in a variety of configurations; and have to say I'm very impressed. Like Ghost it will back up to a networked drive, and it will create a boot CD for when your PC won't boot. See PC World's review at,80031-order,4/description.html .
CNET has a lot of backup program reviews at;sideBar .

Some of these are free (last time I checked there were over 300), some have free trials (over 1000), and some are purchase only (over 200).
External hard drives are best for backup. You can get a 500 GB one for around $70 and a 1.5 TB one for around $90. You can also buy a 16 GB flash drive for as little as $10. It's the best insurance you can ever buy!

I hope this helps. Good luck

Re: backup error
Mar 27, 2013 7:19AM PDT shows it's an 'access denied' error. There's a file somewhere that you're not allowed to read.
It's a good example of a useless user-unfriendly error message, I'd say.

So it might be time to do the same as so many others already did: say goodbye to Windows backup in Vista or Windows 7. There are many superior alternatives.

Our member wpgwpg recommends easeus free backup from or There's a paid version also, but I don't know the difference.

It might make sense to make a difference between the occasional image backup (which allows you to go back to the exact system you made a backup of) and and (incremental) backup of new and changed files (which is fast, easy and reliable, as long is it is just a copy of a file without any encrypting or proprietary formats for the backup files.

For an image backup (and restore) you could use Acronis or open source clonezilla also.
For a file based backup there are programs like syncback or synctoy offering a GUI, or you can write a batchfile using xcopy or robocopy (come with Windows) or xxcopy (free for personal use).

Use Event Viewer to find out errant file(s)
Jun 20, 2015 10:40AM PDT

I had a similar situation on an old Vista computer I was asked to fix. For me the key to solving the puzzle was to open Event Viewer and see if there were any other events around the time that Backup failed. What was happening was that the old Java cache from 2010 in the Volume Shadow Copy (VSC) had 2 viruses hidden in there and Microsoft Security Essentials (MSE) blocked access to the VSC. Backup is not a robust program and so it immediately exited. The other commenters to this thread are correct: there are better backup programs but I was asked to solve this particular problem as the user believed it to be symptomatic of a deeper issue (and there was a certain truth to that).
MSE could not fix the VSC but the event viewer had the name of the original files which were still on the PC (and not detected by the QuickScan which this user normally ran). I deleted all the old Java cache files, made another VSC (by running System Protection, manually creating another restore copy and then deleting old ones by running Disk Cleanup (by selecting the More Options tab, and cleaning up the restore and shadow copy files. Use at your own risk).
Your particular issue may be different but using the event viewer technique to get more information than the cryptic 0x80070005 may help.
Once I had eliminated the old Java cache so that they no longer existed in the VSC, the Microsoft Backup went smoothly.
