Ok I can give more information, and what I already tried:
The destination ist local on the same machine. I changed the temp path and the storage path to a destination on the same machine with plenty of space, I get the same error.
The destination for the temporary folder is a SSD, so I think defragment it is not necessary. Anyway I did a chkdsk and tried to defragment, without any Result.
My setup is
MS SQL Server Express 2014
SQLBackupAndFTP Version is 12.2.1
The destination for storage and SQL-Server is on the same machine
The size of a backup uncompressed is 2 GB, compressed in .zip 1,74 GB
The free space available is 67 GB or 1,3 TB on the other hard disk I tried
I just found out on 24th January there was a new release from sqlbackupandftp installed. Since that day it is not working anymore.
I couldn’t find the release history with versions, details and rlease dates, but on my machine it says the last change on the software was 24th January.
Where do I get the previous version, and which version was that?
Thanks for help. If any more Information is needed for advice I’ll try to provide it.
