After the upgrade, we started experiencing issue when backing up Teams in one of our MS365 Organizations. This message means that your database has a corruption. This is where Veeam’s proactive SureBackup technology comes in! Hello, I’ve started having trouble with a file-level backup on WS2022 via Veeam agent. The customer environment wasn't too worried about the Veeam backups (they have multiple copies) but the backup location was unfortunately used as a data archive location for less critical archived data, which they'd like to recover if possible They've explored the Microsoft support option and that doesn't appear to be avaliable. I am gettin About the checksum, I have read "When writing each data block to the disk, we also write a checksum of this block to the designated area of the backup file (actually, we write the checksum twice for redundancy). The name of the file or folder is . However, I see many suspect_pages recorded for this DB and it even got recorded before the server crash too. This occurs when I try to create or edit a login, when I try to create a new database, basically when I do anything. Thanks for opening a case. 3. On an atom I still wouldn't bother. When restoring, we verify the data obtained from disk against that checksum. Checksums: Think of checksums as a digital fingerprint. Consider the following: Backup data that was mistakenly migrated to the immutable repository cannot be moved to another repository. All backup copy jobs for a specific vm fail with the following error: 9-8-2023 22:31:45 Error: Failed to decompress LZ4 block: Bad crc (original crc: 5a73d881, current crc: 3fa0f4bc). In the meantime, as promised, I have talked to some teams to figure out what exactly is needed and we realized that the "install" rights should be added to the manual, and not only the rights needed during day-to-day running. Storing the data with the rest of the filesystem metadata also seems silly though, so I'm really not sure.

Or should I look into something else? What might cause this issue? What is Health Check?A health check is a planned process within a backup or backup copy job that helps ensure the data integrity of the backup chain. Checked with storage team for health checks, they say no issue. Had a client contact me this morning that is getting corruption errors on their backup copy jobs to the performance tier for their SOBR, but data appear The exact error message: Failed to perform backup file verification Error: A data integrity checksum error occurred.
