Backup Error code: 0x81000019

To find out what is causing the error, since it isn't free space on SysReserved, we need to strip out all of the possible causes, one of which is interference with Win7 boot by XP piggybacking on it. I gave you the steps to unlock the two - take em or leave em.

Try running Disk Check and SFC from DVD Repair console or Repair CD COmmand Line, accessed by pressing Shift + F10 at first screen after booting: SFC -SCANNOW Command SFC -SCANNOW Run in Command Prompt at Boot

You can try booting XP with one-time BIOS Boot Menu key which we can't provide since you have no system specs filled in at bottom left corner of your post. If it works, you can install EasyBCD (older versions are free) to delete XP listing from Edit OS Menu tab.

I would uninstall Symantec and replace it with MSE or Avast6 which is recommended by almost everyone here. This is one more possible problem that will be removed.

We have troubleshot dozens of these problems and they are reparable in some cases if OP is willing to strip out the known possible causes which are by now quite familar to us. You can also simply change imaging apps then watch closely for other symptoms which might be related.

I'd be looking at cleaning up restore points and shadow storage.
The system reserved has adequate shadow copy space but I'd also be looking at the shadow storage allocated on the backup drive and wiping it. This will delete old image versions if you use multiple difference imaging.

No restore points. Following advice that fr0gger received in the thread on system restore timing out, I deleted them. As mentioned, cannot restore anyway due to one of the same errors backing backup.

Dunno what "multiple difference imaging" means (incremental backups?); cannot back up at all. What is "shadow storage?" Do you just mean wipe the disk?

Gregrocker,

Cannot remove W7 boot disk. Too dangerous.

Don't mind disabling XP--even permanently--but, as mentioned, I did not fully understand your instructions re this.

Thanks for the additional suggestions; will take me time to assimilate.

FWIW, looking even less likely than CPUs are cause; just completed a 48 hour test in which both made it all the way.

I certainly don't mean wipe your disk.
It's a long shot but images and restore points need shadow storage to be available.
Go
Control panel > System > System properties > highlight drive >configure

....

Do you mean Control panel > system and security > system > advanced settings > system protection?

Protection is on for C: (W7 boot disk). Space used for restore points is zero; space allowed is all. Protection is off for other two disks.

Are you saying you are ready to remove XP from the Dual Boot?

If so delete the XP listing on msconfig>Boot tab. You can then unplug the HD or format it in Disk Mgmt.

I concur with Michael that System Restore points should never have been turned off and should be kept on. These can help recover your Win7 without having to reinstall as we see frequently here. You need them now, in fact.

What are the exact listings under drives for SysRestore now?

Protection is on for C: (W7 boot disk). Space used for restore points is zero; space allowed is all. Protection is off for other two disks.

I did mean get into "System protection" (by whatever route.
The backup (data) disk normally have protection off but going into "Configure" will show maximum usage. This is the maximum shadow copy storage space which imaging uses. Just check what's been allocated. As I said it's a long shot that it's set too small.

Just check this and then follow gregrocker's strand of thinking rather than bounce you around.

Gregrocker and mjf,

Sorry for slow reply. My difficulties:

-Windows backup
-restore points
-slow application loading
-slow operation of Symantec AV
-links in Office documents not working

all resolved spontaneously about four days ago, before I could implement any of your suggestions (except mjf's to reset which drives had protection (which, once I understood it, was something I had already done).

Took me several days to run a zillion diagnostics but all check out.

My speculation at this point is that the cause was automatic update of something (Windows? Office? Adobe Flash Player?), and that whoever did it realized what they had done and fixed it in their next update. Admittedly a guess.

Thanks again.

Hi there,

Don't know if this thread is dead, but would really appreciate any help - I'm in a bit of a sticky situation:

I've read through the thread and have had similar problems. I've tried a couple of simple fixes (System reserved partition >40MB free space, couldn't extend it...) but I think I need to do the disk partition thing with the Partition Wizard disc.

However, I've been having some boot problems with my laptop: quite often, it won't start, and I'll need to run startup repair for several hours, or several times, for it to run again. More recently, I had to restore the system from the system image on my external HD.

I formatted the partition of my external HD as I though that might be the reason why it wasn't backing up. Now, though, I'm reluctant to turn off my computer and try the PW disc method in case it won't start up again at all (and I'll lose all my data as I don't have a system image).

Is there a risk my computer won't start up again if I turn it off and try to run PW? Is there another way to backup my files? Or should I just copy across the important files I can find and run PW anyway?

Thanks in advance for your help, amazing having this resource online!
