Restore fails but I can mount the backup...options?

Thread needs solution

I was running esxi 5.1 with 2 datastores and Acronis vmprotect 8.1. 1 was raid 1 (hardware) and the other was a single SAS drive. I ran out of room again and wanted to consolidate all the drives to one RAID 5. So, I made a full vm backup with verity on. Installed 2 more SAS drives, Broke the raid 1, created a RAID 5 with all 5 drives. Installed the latest Esxi 5.5. Installed Acronis VM 9 build 10007 appliance to the new machine. Clicked restore full VM. It fails. (log files attached) It has something to do with failing to create the group and the invalid file id's. Since the "Mount backup" is fully working is there a way to migrate that to a permanent VM? Or is there an easy way to fix the restore? I contacted Tech support but they have not gotten back to me. the initial person I spoke with was not very helpful and submitted the information to another level. Case #02310830

Any Suggestions?

Hi Keith,

According to the log file there is a problem accessing the contents of the backup archive on the share (which I assume is some kind of a NAS device). It can be caused by Linux kernel changes which were made in the 9th version (there is known issue with QNAP NAS devices for example). I will send you a link to an updated build of Acronis Backup for VMware (vmProtect 9) which contains a newer kernel with fixes which may help here. If it doesn't help please try deploying a fresh Acronis vmProtect 8 appliance to your new host and perform recovery using this appliance from your existing archive.

Thank you.

It is actually just a share on a Windows 2008 R2 physical server I use for utility purposes. I'm downloading now to try. I was on a chat with 2 different Acronis techs yesterday and last night for over 8 hrs. You would think one would have recommended this. Not sure it will work but I'll try. Waiting for my last attempt to finish (over 10 hrs and at 85%, hard to cancel it. I'm on build 10007 which is latest on the website. Why would this on not replace that??

Hi Keith,

If the share is just a plain Win2k8 one then the newer build might not help (it is supposed to fix the problem with NAS shares handling). I've also seen an "archive corrupted" error in the log file which may indicate that particular recovery point is unrecoverable from that archive. Have you tried restoring any different recovery point for the VM (AppServer) or any other VM from the archive? Likely recovery from another recovery point of this VM will work assuming that at least some VM from that archive is recoverable.

Thank you.

I have tried both backups. 1 is a full backup done right before I reconstructed the server. The other is an incremental that has about 30 backups in it. Both give the same error. The current backup i'm waiting to complete a restore of right now was ran with "validate backup" turned on and it validates successful. I also used "validate backup" when I backed it up and it was successful. The backup also mounts and runs fine. It just won't restore. That is why I was asking if there was a way to migrate the mounted backup to a permanent solution.

the restore runs at about 150Mb/sec up until it copies the partitions and partition structure (around 14%) then drops down in the KB/s and goes back up to about 5MB/sec and stays there. so strange. No matter what we tried it does this. I installed a windows client, i tried copying the backup to another device. I tried copying the backup to a USB device, installed a windows 7 vm on the physical vm and mounting the USB drive to it, then running vmprotect as a windows application on the win 7 vm with local storage...all achieved the same results. Now I have an office full of people getting to work and the whole office is down. After all the precautions I did to make sure I had a reliable backup...So disappointed in the reliability of vmprotect at this point. Case has been escalated and still waiting for a call from an expert that knows more than the 2 techs I spoke with yesterday

well, the last restore succeeded. Not sure what changed. but at this point I'm just happy to have it back. I really would like to know why the data rate transferring the partitions was abysmal though for future reference.

Hi Keith,

The behavior you describe (the fact that archive is validated properly, but recovery still fails) leads me to conclusion that the issue is in the channel (network) between the ESXi host and Acronis Agent (appliance or Windows Agent), but this needs to be confirmed by getting debug logs. I've talked to our support expert (Vyacheslav Bykov) who's going to handle the case and explained our current thoughts. So while the VM has been restored successfully, we still want to find out what was the root cause of the issue - the failure was caused by different errors and while one of them has detected an archive corruption, then 2nd one returned a general Input/Output error, therefore it's unclear at the moment (should become clear once we get more detailed logs).

P.S. forgot to add FYI: we're currently working on adding an option to finalize a mounted VM permanently on datastore - we already have a script prototype which does the job, but the functionality needs to be added into the product GUI, so it's pending for the next version.

Thank you.
