compare backup drive hashes

We have hosted the application compare backup drive hashes in order to run this application in our online workstations with Wine or directly.

Quick description about compare backup drive hashes:

This project offers an Excel spreadsheet, available for download through the Files tab (above).

The spreadsheet allows the user to compare two sets of file hashes, such as the hashes for files on two different data drives. The spreadsheet's Instructions tab provides step-by-step guidance through that comparison process.

The purpose of the file hash comparison is to identify files whose contents have changed. For example, the files on an up-to-date data drive may be compared against the files previously found on that data drive, or on a backup drive.

Identifying changed files may be useful as a precaution against ransomware. The Support tab (above) links to a blog post discussing uses of the spreadsheet for that purpose. See also https: //raywoodcockslatest.wordpress.com/2022/04/10/ransomware-spreadsheet/.

Features:

• Import hash lists from a variety of hashing tools
• Facilitate comparison of Windows and Linux drives
• Detect file corruption despite on-the-fly ransomware decryption
• Preserve a history of file changes
