Backup of Journalreceivers

Good morning Volker,

big misunderstanding on my side!. Of course I can't set the THRESHOLD to 1
TB (especially when my whole storage is only 1 TB!!)

You can call me "Knoedelhead"...

Hi Franz,

nobody asked you to change the threshold to 1TB and I wouldn't do
so,
because then your system would definitely blow up!
That would mean, that a receiver would get only changed after 1TB!!!

The change described below ONLY changes the MAXIMUM receiver size to
1TB, so
that it doesn't stop working at 2GB and run into MSGW.

Regards

Volker
