Windows 7: Backup no longer works

14 Aug 2010   #41


Last week we had a case where Win7 Backup Imaging wouldn't save the image because the Sys Reserved (boot) partition didn't have enough unused space for VSS to create a file. Research on the Backup error led to this discovery, which was solved by recovering the Sys Reserved MBR into the Win7 partition.

There are other complications which Boot Managers can cause to crop up which are entirely unnecessary if you have separate HD's since they can be much more cleanly booted via the BIOS.

Thanks again, Greg. I dumped the Sys Reserved partition a long time ago.
Any thoughts on why other backup applications like Timeline and Acronis True Image work and Windows Backup doesn't?
Also, why did it work for almost a year, and just stop working with no changes to the system?

My point is that if something as obscure as not having enough unused space on the boot partition could cause Backup to fail, then the perils of using a third party boot manager partition ought to be obvious.

We have nothing but problems with GRUB and Win7 which is relatively stable compared to most of these.

As to why it could fail after a year, there is no easy answer to that as it could be almost anything. You may be lucky it ran for a year without problems.

Maybe if you Google or post a thread in General with the exact boot manager name in title it will attract someone who has had this problem and sussed it out more exactly.

Greg, I completely understand what you are saying, and I'm not trying to be awkward - honest!
I just wondered what possible reason could there be for it to work OK for many months, and then stop working.
I also just wondered why True Image and Timeline also work under the boot manager. Do they not use the VSS service?
I'm not questioning how unwise it is to use a boot manager, I'm only curious.
Thanks again.
