I created a 'succesful' backup and try to restore it to my staging website. The archive is split into 8x20MB (j01-j08) and a jpa file. After the backup the jpa file is 0 bytes (??). This looked wierd to me so i tried several times but every time the same.
When i do an install with kickstart (unpacking the archive files) i see the following error: The archive file is corrupt, truncated or archive parts are missing.
What might be the issue here?
Can you try setting the part size for split archives to 21 MiB and take a new backup? Do you still get a zero bytes file?

Hi Nicholas,
After changing the spilt archive size to 21MB i suddenly get a much larger backup. 481MB instead of 160MB. The jpa-file is 19.5MB now.
I make a backup every month via a cron job and when is look back the backups from december until today were all 160MB with a 0 MB jpa-file.
When i copy the new file-set the extraction is fine and i'm sure the rest of the install will also succeed.
For sure i will check the backups of my other websites and when the jpa-file is 0 bytes., I know there is something wrong...
Changing the part size won't change your backup size, but what happened here gave me a good clue to help you further (as I hoped it would, and even better to be perfectly honest).
The previous backups seems to have been incomplete.
That would explain why there were fewer parts and why the last part written to was 0 bytes.

I finaly found the issue. On this specific website i have a downloadable exe file with a very long filename like: rustdesk-host=pt.xxxxxx.me,key=NOrO5X0BYZ34ahCZn+6EMbaHokDlbSrFsIIFpaNuVOY=,.exe
When this file is in the backup, the backup breaks and the jpa file is 0 bytes long.
Now that i excluded this file from the backup the backup is okay. Now that i know what the cause is, it's not a real problem for me anymore.
Ah, I see! PHP timed out while taking a backup. The backup had never finished, that's why the archive was broken and Kickstart complaining about it.
