It seems not to be a problem of the backup-file, but of the restore-process.

When I looked into #Settings#Apps#MobileSheetsPro after the crash I got
Gesamt 3,87 GB
App 77,88 MB
USB-Speicher-App 0,00 B
Daten 465 MB
SD-Karte 3,77 GB

There was a message "zuwenig Speicher" (not enough memory).

After deinstallation and reinstallation of MsP, I restored the same backup-file successfully.

I don't know what had happen, but now the system is working correct.

I always use the restore-options "delete all existing files" and "restore settings from backup" (german verison).
The samsung tablet, where I have created the backup, doesn't has a SD-memory-card. On the POV-tablet I have to use the SD-memory for the MS-files. Maybe the "restore settiungs from backup"-option is responsible for the problems?
