Share this article if you think it is worth sharing. I hope this helps you to fix your Broken Backup Chain in Veeam Backup & Replication. So, no backups for those VMs.Īfter you fix the Broken Backup Chain, you can now restore any VM (using the available restore points). Note: It could even happen if you have new VMs backup in those corrupted incremental will no longer be available(in this example, had 20 VMs that were not available anymore). So it means that all incremental were corrupt, or files were deleted (for example, 2 and 3 from our Incremental initial image).Īs you can check in the next image, all VMs have only one restore point available.
Note: Depending on your system and backup sizes, this procedure can take a while.Īfter Veeam removes all corrupted files, the only available restore point was the initial Full Backup. Just confirm and let Veeam remove all corrupted restore points and fix the Backup Chain. You can use this option just for the safe side and if you plan to try to recover the missing files. If you find the missing files or see that the files are just miss-located(maybe in a different Repository that was set to maintenance mode), you can then import all Backup Chains to the Backup Inventory. With this option, Backups will only be removed from Backup Inventory, not psychically. For now, you will fix the broken chain then, you can troubleshoot what happened to the missing files. Why Forget option: I choose this option because I don’t know what happens to the missing incremental files and would not like to lose any VMs backup(when using the delete option). To remove all restore points from the unavailable extent, select All unavailable backups.įor this particular case, I choose to option Forget and with the select All unavailable backups.To remove only the selected restore point and restore points that depend on it (a part of the backup chain starting from this restore point), select This and dependent backups.There is also an option to perform this task only in the select Job/Restore Point or do for all for the Forget and Delete options. Delete - you can remove records about missing restore points from the configuration database and delete backup files from the disk.
Veeam Backup & Replication will “forget” these restore points and not display them in the console.
This can only happen if there are issues with your Storage Repository, or you put one Repository Offline in maintenance mode, and some files will be unavailable, or someone deleted the files manually in the wrong sequence.Įven if you choose a different restore point or even the full restore point, you get the same error. The VM was created in the vCenter, but you cannot power it on, and there is no Virtual Disk. When checking the last line in the restore log, the incremental. When you try to restore the VM, you get a backup with a broken chain and get the error: “Backup files are unavailable.”Įven when you get this error, the VM restore continues and finishes with the next image.
You can now choose one of the restore points to restore the VM. I will discuss in this article when you try to restore a VM with a Backup that has a broken chain, you get an error: “Backup files are unavailable.”Īs you can see in the next screenshot, this VM had four restore points. Note: “Reverse Incremental” is always a slow backup compared with “Incremental.” Since the last backup will always be a full backup and all incremental will be injected in the last backup. With this option is more difficult to have a Broken Backup Chain. Mainly if you are not using “Reverse Incremental.” Increments are always injected in the last backup to create a full backup.
This article will explain How to fix Broken backup chain in Veeam Backup & Replication.Ī Broken Backup Chain is when you have a full Backup(.vbk) and several (can be 2 or more) incremental(.vib) that were deleted or corrupted.
