Backup over VPN keeps failing :(

[Lincee (Jan Jacobs)]

So, i have created and connected 2 OpenVPN servers, this works like a charm, and i can access the network on either side.

However, backup keep failing
it stops with volume 35, beeing 90,3MB big.
i have run 5 different backups now, and they all fail at volume 35, 90,3MB big.

I would think, if these where network problems, they would occur randomly, also, at the moment the backup fails, i can still access the share

Does anybody know whats happening here?

also, free space is available triple the size of the backup, so this shouldn’t be a problem?

here’s the log:

Uhm looks like you have network problems. Can you try with a local backup? Like a shared folder on another server or a local NAS?
