Mail Backup Issue

Hello,

My backup does not work anymore. The encrupted folder contains only old backups

root@mail:/home/user-data/backup/encrypted# ls -ali

when trying to run the backup manually :

If you have a little idea, I’m interested!


Rsync backup local vs. remote
#2

Have you recently migrated from the Ubuntu 14 to Ubuntu 18 version? Which version of MiaB are you presently running?


#3

No, it’s a fresh Install on Ubuntu 18 (The migration from Ubuntu 14 was done by IMAP)

The backup worked well at first.
