Backups failing after RAID drive failure

Thread needs solution

Swapped-in a replacement hard drive and added to RAID (5). Most, but not all, back-ups are now failing with a host of errors referencing e.g. database, hash issues (see attached.

Suspect something has become seriously corrupted as a result of the original hard drive failure so all advice most welcome.

Typical failure error log entry attached.

Many thanks in advance.

Hello Steve,

Welcome to Acronis forums! I've checked the log file, apparently the deduplication database got corrupted as we see sets of errors like 

Failed to process the deduplication request
There is an error in the hash database
A database error has occurred

I'd suggested the following course of actions:

1. First of all please update all components to the latest build (you can download it under your account at acronis.com)

2. Then re-create the dedup database using instructions from How To Migrate to New Deduplication Algorithm. This will help us to kill two birds with one stone - rebuild the database and make use of the new dedup algorithm. The operation may take significant time depending on the amount of unique data and available resources on the server. 

Please post back with the results, hope the migration will help you to fix the issue. 

I'd also recommend checking Deduplication best practices part of the documentation. Make sure your setup meets the outlined requirements. 

Thank you,
