ASR 24 poor backup performance (Win11 24H2)
I have been using System Recovery for many years, starting with Symantec System Recovery, migrating to Veritas System Recovery, and now I have moved to Arctera System Recovery 24 for my new Windows 11 machine.
I am currently experiencing a frustrating issue with all backups in Arctera System Recovery 24. Whenever I start a drive backup task, everything starts out normal. It builds the snapshop and starts copying files as expected. But inevitably, after the backup task has been running for about 15-20 minutes, the performance completely drops off. I can see the disk activity in Task Manager for the target drive and it goes from a consistent write speed for the first 15-20 minutes, to an extremely inconsistent write speed that spikes up and down. Task Manager shows low CPU usage, low memory usage, and low disk usage, so there should be plenty of resources available. I have tried backups both with and without compression, and the same issue occurs regardless. Backup tasks that should complete in 5-6 hours would require something closer to 36-48 hours to complete, and this performance makes it impossible for me to backup my drives.
This performance is not unique to a single drive. I have experienced the same result with backups of 3 different high-speed NVMe drives, using 2 different USB target drives. And those same USB drives were used in Veritas System Recovery on Windows 10 with no issues whatsoever. I can also do a full copy of drive contents in Windows from the source drive to the target USB drive without any slowdown. A copy/paste of full drive contents (~ 3TB) finished in under 6 hours. A drive backup of that same drive would take about 2 days. I am leaning toward this being a software issue, as there are no indications of any hardware problems. Crystal DiskMark benchmarks of all drives appear to be completely normal.
I am currently working with Arctera support and they have been very responsive, but we haven't found any answers yet. I just wanted to check here and see whether anyone has experienced this type of issue, with ASR 24 or any other version. If so, were you able to figure out what the problem was and how did you solve it?
Hopefully someone can provide guidance. Thank you!
