Hello,
I have a 3 server cluster (PVE 8.3) and a PBS server (ver 3.4) all on a 192.168.1.x admin network. I have 1G nics and just added a 10G nic to each node and the PBS. My storage is setup with a 192.168.1.x network and all other server application traffic goes trough seperate nics on a 10.0.xx network. I want to setup the 10G pipe on a 192.168.2.x network for backup and replication. I already have the Migration Settings on the 192.168.2.x config. Now my pbsbackup storage is config with the 192.168.1.x ip for the PBS server. how can I change that ip to use the 10G network (192.168.2.x) for backup while leaving the 192.168.1.x for cluster administration.

Sorry but your answer is ambiguous. what happens to the existing definition of the storage in Datacenter. where and how is this network interface defined. what happens to the backups already done to this storage definition.
 
The existing storage network is not affected. You only need to add a network that can communicate with your PBS, and when you add /modify the PBS storage it will try to reach the PBS by the new IP address.
 
Hi, I would like to understand the working of the backup storage link definition.
In Datacenter console in storage I added three storage devices :
1. backup01 server: 192.168.1.44 Datastore: Daily Fingerprint: xxxxxxxx
2. usb01 server: 192.168.1.44 Datastore: Usb01 Fingerprint: xxxxxxxxx
3. usb02 server: 192.168.1.44 Datastore: Usb02 Fingerprint: xxxxxxxxx

backup01 is used for my daily backups, usb01 is for weekly and monthly usb02 if for yearly for offsite save. so I would have to create 3 new definitions say,

4. backup10 server: 292.168.2.24 Datastore: Daily Fingerprint: xxxxxxxxx
5. usb101 server: 192.168.2.24 Datastore: Usb01 Fingerprint: xxxxxxxxx
6. usb102 server: 192.168.2.24 Datastore: Usb02 Fingerprint: xxxxxxxxx

and use these as the storage in the backup jobs, if I am understanding the workings. And these will continue updating the incremental backups I'm currently doing but using the 10G pipe.
 
OK, so how do I make backups to move offsite for Business Continuity. also my main concern is how to start using the 10G network still keeping all the backups done so far accessible.

Is not a good idea making backups in different datastores as you miss the dirty bit, so every time you do a backup weekly or monthly is a new copy not incremental.

For a copy that will be taken offsite, this is desired. A full backup taken offsite that is complete and can be used to recover everything in the event of disaster.

I recommend having an offsite PBS server, but I also get that this isn't so easy for everyone. Anything that gets you a copy of your files offsite is a great way to do it.
 
hi, please confirm the setup changes to use the 10G network for backups vs the 1G NIC without loosing existing backups on datastore.

There is no reason to loose backups, because you only are moving the storage network, not the storage itself. I mean, for example if you put another PVE and add storage pointing for this datastore yo can see all the backups of the first PVE. The network has no effect in the storage, is only the way to achieve it
