what is the purpose of the sync option

**re added as i edited it and for some reason it deleted the thread?**
might sound a dumb question but hear me out
Two proxmox instances physically apart both host pbs as a vm ( yes not ideal but limitations on hardware dictate it)
first one has mounted iscsi for storage hosted on truenas which is also backed up in there (truenas) to a usb drive
second one uses a vm partitioned disk for backups but also has usb drive passed through to duplicate the backups.

1 also syncs some of the important machines to 2
2 also syncs some of the important machines to 1

the syncs sit in a different namespace on each others pbs disk e,g root (1) has a name space called 2 and root (2) has a name space called 1
all this happens every night almost 100% successfully

let's say 1 has a fire/ machine ending event happen, so i would need get 2 to spin up the the critical machines 1 was hosting that it regularly synced over to 2's pbs under the 1 name space

how do you do it? i can see the pbs 2 storage with pbs 2 backups available to restore in pb 2, but i can't see that name space called (1) in order for me to do a restore from the synced vms/lxc's from 1
am i missing something simple or is that not what Sync is for?

thanks for any pointers

worked it out, for those who get into a similar situation, you need to add an additional pbs disk to pb (duplicate everything your current pbs disk is (fingerprint, disk, user/pass but you put the name space that you have put in pbs, so in the example above you add 1 name space and not root. looks like you can mount both at the same time which is good
