Trying to restore from a backup and I keep getting an error

[Firecracker048]

Good Morning,
So recently I had to reinstall proxmox on a new SSD after the last one shit the bed. I tried to clone the drive directly but the MBR was the sector that was broken, so the cloning failed.

After doing a fresh install ive tried to restore from backups and I keep getting this error:
_25-15_16_26.vma.zst : Decoding error (36) : Restored data doesn't match checksum
vma: restore failed - short vma extent (1415168 < 1446400)

Ive tried 3 restores now, and the first two gave me error 133. Now on the 3rd try I get the above error. What is the issue?

Edit: So at the end I did get error 133 again. Here is the full output:
_25-15_16_26.vma.zst : Decoding error (36) : Restored data doesn't match checksum
vma: restore failed - short vma extent (1415168 < 1446400)

Sounds like the backup(s) might be corrupt. Describe the backing storage on the system that houses the backups; also could be a RAM issue, are you using ECC?

Backup storage is an SMB file share to my personal PC that is a HDD.

Server uses ECC, personal PC does not

Try running a chkdsk and a SMART long test on the Windows box

Also check your powered-on hours with Crystal Disk or similar, most HDs are only warrantied for 3-5 years. Might be less if it's a lightweight WD "blue" drive or similar desktop-class. If uptime is near/past ~43000 hours then it might need replacing

For future backups, might be worth build a small ZFS server with at least a mirror, so you get self-healing scrubs.
