There are two issues just fixed regarding to Restore Points creation. One was related to fat32 incompatible files, another to removing old restore points.
These fixes become available for customers since version 3.0.3.737.
So far next actions may help to fix:
1. remove files similar to jdata/spoofing_2019-09-12 12:53:54.log and don't use spoofing screenshots until you have fixed build mentioned above.
2. remove jbackup folder from SD card. May help if you have no free space on SD.
If none of solutions helps or version 3.0.3.737(and newer) doesn't resolve the issue, please write here or to me directly.
