Backup slow after latest update (April 2021)

Thread needs solution

My backups, of an M2 disk to a NAS, have always run very fast, 800mb/s being typical.

ATI updated itself last week.  Now my full backup is running at 96mb/s, so taking eight times as long.

Was there a change in the latest update?  How can I resolve this?

Clive, very difficult to guess at why your backup to NAS has suddenly become so much slower?

What was the update from, was this from ATI 2021 build 39184 to 39216, or from an earlier version of ATI to the latest 2021 build?

Has your backup finished yet and if so, what does the Activity page show as the Speed for this latest backup and for previous backups?

If this does show such a big difference, then I would recommend opening a Support Case direct with Acronis so that they both know of the issue and can investigate with you to determine why there is such a slow down!
