    @Pilow [image: 1776289093675-eac3d82b-82a4-46b3-b8e1-1f4b64c57e35-image.jpeg] The number of snapshots shows 16, which makes sense as I have two backup schedules, one with a retention of 15 and one with a retention of 1. The daily backup with a retention of 1 resets the chain, as it is a full backup. [image: 1776289174076-883856d8-222a-4593-a013-3204a340ecbc-image.jpeg]

    @rzr (edit) After upgrading two main pools, I'm having CR delta backup issues. Everything was working before the XCP update, now every VM has the same error of Backup fell back to a full.

    @denis.grilli The problem is not the performance of the scan ... the problem is, that this storage device only consists of block devices (disks) that should go into standby mode when not used ... but I think I've found a code line that checks if other-config for an SR contains auto-scan: false...

    @Pilow Thanks for the heads-up, you should be able to add back concurrency as it was before and get similar performance to before the refactoring.
