Thank you for your quick answers and advices, I’ll do more research and give restricted access…
The tape backups are not an option as the budget is limited and the datacenter doesn’t propose that option with this server.
Concerning the another physical location it’s already the purpose of the backup server as I already have backups on other disks on the local PVE and also on a network share on a different physical location but directly mounted (and accessible with no protection) on the PVE server so for the whole point of this backup server is to already get a different physical location and since it’s a pretty basic and simple system I could as well setup a rsync script that would retrieve the backups files already managed by the PVE itself on then backup server…
But apparently the creation of a limited account gives me the same kind of security with all the advantages of deduplication, limited bandwidth, scalability of retention etc… so I think I’ll go that way 😉
Thanks again for sharing
