Can not restore Backup
Hello,
yesterday July 11 my Win10 got busted-can not enter anymore... no problem, I have daily backup with Acronis-that what I thought. With the Rescue DVD I enter the backup directory and click restore July 10 Backup, but I get the message: Backup archive file is corrupted. If the backup is an image, you may try to recover.......
So I clicked July 9, 8, 7, 6, -all the same message. (On July 10 I input a lot of important data, I will have a hard time to recover otherwise)
I have no idea what files backup it created..., they all have extention . tib
How can I get the backup working?
Please suggest!
Thank you!'
Dorian
UPDATE:
I am sorry, I was mistaken: The corruption msgs are from June-June 9, 8, 7 and so. When I found the July backups way up, it gave me the following msg: This is not the last volume of the backup archive. But I don't see any later ones.
How can I restore those?
I hope my screenshot uploads as well
Hello Jose,
thank you for the links, but they don't tell me what to do when I get thew message: This is not the last volume of the backup archive. I clicked on my very last of my backups.
Or do I need to restore my full backup first and then the incremental?
Please advice.
Thank you.
Dorian
I checked most of my backups.
The last 3 days it says: This is not the Last Volume .......
All other backups are corrupted! Including the full disk Backup!
All the backups were done on an internal SDD.

Hello, Dorian.
If the entire chain is corrupt and you have confirmed that there's not much you can do, the restoration of corrupt backups is not possible. However, you could try to recover specific files from the .tib file, as I mentioned above.
Unfortunately this version of the product isn't support anymore since 4 or 5 years ago so we can't even proceed with an investigation.
Thanks in advance!
Hello Jose,
the files itself are nit a problem, since I can access the drive and can copy them to an other drive (I will use the backup Drive with my corrupted Acronis.
But how can this happen? Acronis is not a free download from a shady Chinese Website.....
I paid a lot of money for it... I really lost my trust in a product like this.
Why can it not inform me that the daily backups are corrupted-not one but day by day?
After the Backup It should confirm that it is functional and is not corrupted. And then keep on going day by day...? The backup was to an internal SSD not an external one.
How can I ever trust this software again?
Thanks
Dorian
Dorian, the key issue here is the fact that your backups have become muddled because of file conflicts when creating new backup versions as shown in your screen image file listing.
Each time Acronis encounters an existing file by the same name the file name is given a numeric suffix, i.e. 1-2, 1-3 etc. Your listing has a lot of such files.
What I would suggest trying is to take the most recent backup file, i.e. one from 7/10/2023 if you have it, then in Explorer, right-click on that file and look for an Acronis option. Select that option to open up further options and select to Validate the version chain the file belongs to. This will try to walk back along the chain to find all the required incremental segments.
It is important to note that an incremental version chain will be broken if any incremental segment is missing - this is inherent in the design because you are backing up only the changed data identified since the previous file was created. If there is a missing file, then all further files beyond that point are rendered useless!
Another approach is to start at the other end, i.e. the beginning of the version chain - test that the initial Full backup version is good, then move forward with the following incremental files until you reach a file that fails!

Hello Dorian.
The product has the validation option to confirm the integrity of the backup. Happens it's not enabled by default. You must enable it yourself in the backup plan. Please note that will increase the time it takes to finish a backup.
Thanks in advance!
Hi Steve,
I understand somehow how the backup system works. On day 0 you make a full backup, day one only backs up what you added, so day 2 etc.
When you want to restore on day 30, all backups from day 0 to 30 must be intact.
can not be one missing. That is clear to me, but not, why they all are corrupted!
Thanks
Dorian
Hi Jose,
I really don't remember if the validation option was enabled. Before I junk it out I will give it an other try and be very careful to enable validation. Which backup is saver? I remember there is incremental and an other one?
Thanks
Dorian
Hello Steve,
I forgot to mention, that all but 3 files were corrupted including the full backup! Meaning from day 0 27 days all files were corrupted. I tried to restore day by day backwards.
Unfortunately I erased the disk already, because I needed space to copy over the files from the busted C drive. But looking at the screenshot I uploaded: on 7/1/ I have 2 backups v_1.tib und v1-2.tib. Both on the same day.
On 7/6/ I have v1-2.tib then 7/7 and 7/8 none (even I choose daily backups) and on 7/9 v1-3.tib.
What does that mean?
Thanks
Dorian
Hello,
Somehow I was in luck and found my very first backup with Acronis done in March.
It stopped incremental Backup, it gave me a message it can not find the disk. Maybe the disk was busted? So I removed it, put it aside and totally forgot about it.
Only today I found it again and checked the directory, and I found 1 full and 5 incremental daily backups. Of course I tried to restore from the last saved one. It restored, Message says it is done-reboot but then once was the MBR missing an other time asking for a boot disk, so I decided to restore from the full backup. That worked.
Well, even the backup is 4 months old, I am glad I did not have to start all over again.
To avoid in future those problems and I need to restore again, I would like to know why it did not restore correctly?
At least this time it did not give me the corrupted data message.
Thank you.

Hello Dorian.
Without logs and troubleshooting it's not possible to tell you why the recovery wasn't successful previously. I would say that you tried to recover a corrupt slice of backup. But many reasons can be behind that behavior.
