we have upgraded from 2020R2 to 2022R1.  Ever since, in both our SaaS Acumatica and our AWS sandbox, I have not been able to get a snapshot to export.  The snapshot will complete as long as I do not ask to prepare for export.  But then when I tell it to prepare for XML export, I get the following error after about 10 minutes

The operation has been aborted.

I have plenty of space, and have actually deleted all the old snapshots.  Also I have ran the optimize database after each delete and failed attempt.  I have also restarted application after database optimization and nothing seems to help.

Any ideas would be greatly appreciated.

The error usually occurs when an individual table is more than 2GB, the system is unable to zip the tables into a snapshot and aborts the process. You can check the same by navigating to Space Usage form > Snapshots tab > tables, sort them in descending order.

Note: This limitation has been fixed in 2022R116, 2022R206 and later versions.

Based on the snapshot requirements and usage-

• If the created snapshot needs to be imported to the same instance, instead of exporting and importing the Snapshot kindly try the Change Visibility functionality by following the steps-  https://help-2021r2.acumatica.com/(W(66))/Help?ScreenId=ShowWiki&pageid=e12b9fcd-9e96-4366-97d5-a262b505c87a
• If you haven’t already, try exporting using the Binary format instead of XML
• Another workaround is to create a custom snapshot to remove the individual table causing the issue - https://help-2021r2.acumatica.com/(W(2))/Help?ScreenId=ShowWiki&pageid=7e3a77ec-e8b5-4f68-8365-e2e20a9d6208

Hope this helps!
