Veeam Failed To Decompress Lz4 Block Bad Crc

check our backups, some months later Veeam created the veeam.backup.validator tool.We've run this now on several of our backups and it has reported that some others are also corrupt.

it appears to work ok, the virtual server boots up and runs, you can run a chkdsk on the virtual machine and it comes back clean, however if you happen to run a program that accesses data in the corrupt region of the backup then the whole virtual machines crashes.It is impossible to restore the whole virtual machine as the restore process crashes out because of the zlib decompression error.Veeam have advised that there is a custom agent that can bypass the corrupted blocks but that is not acceptable.I think its very important to point out to the community these 4 points. 1. Just because the Job reports success doesn't mean the backup was successful. 2. The "Enable automatic backup integrity checks" doesn't detect decompression errors. 3. The surebackup job will not verify that the backup image is error free or free of decompression errors / corruption. 4. The only way of validating the backup is successful is to perform a full restore or run the veeam.backup.validator tool.I would be interested to see if anybody is checking their backups any further than with a surebackup.If not, i would advise them do so pretty sharply.The case is still grumbling on after about 6 months, I have found a problem
