Hello Skyvia Teams,
I want to know how backup work in Skyvia i have taken the backup of my org but when i restor the bacckup ist giving me error.
After detailed investigation, we see that you are getting Object 'ContentDocument' doesn't support insert operations error when performing restore operation for "ContentDocument" object.
According to Object Reference for Salesforce, this object does not support "Insert" call.
Should you have any further questions, let us know.
