Full disk backups getting slower each week

Thread needs solution

Seems similar to the version chain post but I'm posting as possbly different problem.

Using Win 11 - Fully Patched and Cyber Protect home - Fully Patched.

I do a full disk backup of my 3 drives once a week overnight  (3 seperate jobs running at different times) to an external USB3 HDD and have it set to keep the last 3 backups of each drive.

It's a full backup, not incremental or diffrencial.

The backups are getting slower and slower each week.

As an example.

My D: drive has about 950GB of data to backup and has only increased slightly. Maybe another 40GB.

Week 1 - 1h38m

Week 2 - 5h11m

Week 3 - 5h8m

Week 4 - 7h54m

Week 5 - 14h27m

Same is happening with the C: and E: drives but they are quicker drives and smaller amount to backup so not as big an issue.

All drives SMART data is reporting OK in crystaldisk info and speed test with crystaldiskmark all look normal.

The external USB drive is 8GB and about 1/2 capacity.

As a test I cloned the D: drive backup job and ran it manually and it took 1h58m, with me using the PC while it was working. So that tells me hardware wise things look ok.

I re-ran the original job manually and aborted it after about 1h30m as it was crawling along.

So the only differnce between the two jobs is one has previously ran and got previous backups and the other hasn't.

But as they are full backups that shouldn't make a difference. Should it ? 

I'm re-running the cloned backup again to see if that increases as a test. So far it looks to be running slower.

Any sugestions\ideas what to check next ?

Thanks

Steve

Hello Steve!

To troubleshoot this issue, I suggest you try the following steps:

  1. Check your system resources. Make sure your computer meets the minimum requirements for Acronis software and check if there are any background applications or processes that may be affecting the backup speed.
  2. Check your hard drive for errors. Run a disk check to make sure there are no issues with your hard drive. https://learn.microsoft.com/en-us/windows-server/administration/windows…
  3. Check your backup settings. Make sure the backup settings are optimized for your system and that you are not backing up unnecessary files.

If the issue persists, please contact our support, because this kind of issues with performance require additional troubleshooting. https://kb.acronis.com/content/8153

Thanks.

 

This can happen if you do a full verification after each backup, rather than just verifying the most recent update.

Thanks for the feedback guys.

Jose, yes already tried those steps. I have a high spec machine and no drive errors on any of my disks. High end processor and plenty of RAM available.

Ian, I'm not performing any post backup verifications.

I re-run the cloned backup again and it did take longer the second time. Went from about 1h54m up to 2h33m for the same amount of data.
