Unable to restore a backup

Thread needs solution

This seems odd to me.

I ran into problems running Windows 8 - the system seemed to "freeze" and, when I checked the Event Viewer, I found repeated attempts to read a specific sector. Eventually the read succeeded and my system returned to normal, but I thought it was probably a good idea to restore one of my later backups.

I replaced my laptop disc with a different disc and attempted to restore my latest backup. The restore failed after telling me it could not write to one of the sectors. Fair enough. I ran Windows disc check on my disc and found no errors. I then ran it on the disc containing the backup and found no errors. I then did a verify on the backup and it said everything was fine. No problems on my system disc, no problems on my backup disc and the backup verify succeeded. However I could not restore the backup.

I then tried the previous backup and that failed as well. Same issue. I had to keep trying backups until I found one (quite a bit older) that succeeded. I am now busy restoring stuff from the original disc to the restored disc, but I still don't understand why the restore attempts failed. If the backup verifies as OK and if the disc checking utility says both discs are OK, why would a restore fail?

As if this was not bad enough, my attempts to do a backup of the original failing disc also failed. That is, before I swapped out my system disc I tried to backup the system. The process Acronis spun off to do the backup failed and reported that it had failed. I have no idea why it failed - I just got the popup windows saying the process failed. No explanation as to why or what to do about it. I made several attempts including a restart between attempts. Nothing made any difference. All attempts failed, all without any further information than Process Failed.

This was with Acronis 2013, build 6514. This is TrueImage Home, but is a fully licensed version.

We have seen chkdsk miss some bad sectors, in particular when the corruption is in a hidden partition.
If a file is corrupted because of a bad sector, chkdsk might not repair it. FInding the file and deleting it (if possible) can solve the issue.
Using disk diagnostics tools from your disk manufacturer (typically ran off line of Windows) is better than chkdsk.

If your backup contains a corrupted file system, you can restore your backup sector by sector to some unallocated space (a portion of a disk without any partition), then run a disk check/fix tool then back up again.

In this particular case the bad sectors, assuming that is the problem, are not in a hidden partition. I have tried to restore both the entire backup and the main system partition. Both attempts failed. And, in what is most puzzling to me, the attempts failed before the actual reboot to do the work. The process just died and I got no explanation as to why.

I have never tried to restore a backup sector by sector. Is that an automatic operation? Or a manual one? I cannot imagine trying to restore a large system disc sector by sector manually.

I have never before had problems with backups and restores with Acronis. I have been using it since TrueImage 10 and now, with 2013, I suddenly find that I have 3 backups, all of which Acronis tells me are OK (they verify as fine), but none of which will actually restore. And they won't restore to either of two discs so it should not be the destination disc that is the problem. And the source disc, none of which is hidden, also seems OK according to chkdsk.

Very puzzling and a bit frustrating. Fortunately for me none of this is critical.

Have you tried to perform the restore form bootable Rescue Media?

There should be no "attempts failed before the actual reboot to do the work" issues if done from the Rescue Media.

It is odd because, for some reason, I did not think about doing a backup from the rescue media until sometime yesterday afternoon. I think about doing restores from the rescue media (sometimes because I have no choice), but not backups.

In any case it finally did occur to me and I was able to successfully get a backup started that way. It failed (bad sectors on the disc being backed up), but I was at least able to get one started.
