XG Backup Password Verification

Kinan Akel

Hi,

I wonder if anyone knows the encryption algorithm used for Sophos XG Backup files.

Or better, if Sophos provides a way to verify the backup files without restoring it.

Because restoring the backup files will require downtime, which no one likes, and verifying the backup files on frequent basis is a requirements of the operational team.

Any idea / hint / lead would be appreciated.

Regards,

    Run this command in a Linux box or Windows WSL:

    openssl enc -d -aes-256-cbc -in nameofbackupfile -out backup.xg.tgz -md md5  -pass pass:passwordforthebackup

    Then, the TAR file (backup.xg.tgz) needs to be extracted.

    INFO: While you can take a look at the backup to know how some things work, its totally NOT recommended to edit the dumpdb file and then load it again in a firewall.
