Hello together,
iam a student assistant administrator of an institute of our university and i am just searching for a solution for backup.
I have a big Open-e NAS-R3 server that should be used for it, unfortunately i have no idea how to use it.

The first problem is, i cant connect to open-e with rsync. Thats the error:
Code:
# rsync -raRx --acls --whole-file --delete --force "./" "backup@nas-backupserver::testshare"
rsync: failed to connect to xxx.yyy.zzz.www: Connection refused (111)
rsync error: error in socket IO (code 10) at clientserver.c(98)
The second problem is, open-e does only accept connections from local intranet. The open-e server is working in our internal network, but i want to backup my webserver which is working inside a DMZ subnet, too. How do i solve that?

At the Moment i use rsync with a cron-script to make a snapshot of every server every night. The current backupserver moves that snapshots to get daily backups for one week, weekly backups for one month and monthly backups for 3 month. Can i get that with open-e, too?
