Hi guys
i have a problem, i searched the forum but i can't find any hint about it, or at least nothing that i can understand.
So, i created a zfs mirror pool to store my backup on my server and called it DATI. The system won't let me use it for backup so i create a folder via GUI called BKPLOCAL, so if i click it on edit it say DIRECTORY: /DATI. I use it for my backup and everything is ok.
Now, i need to take one of those backup and move to another location but can't find a way!! How do i access the folder that i created and copy my file? I can't find a way! ANy help?
Thanks guys
 
Can you send me the output of the following commands?

cat /etc/pve/storage.cfg
pvesm status
zpool status -v
df -h

THANK YOU FOR THE HELP YOU ARE PROVIDING!!
 
Backups should be located under: /DATI/dump
 
Depending on what your use case is. Do you want to share it once with just one computer? Just use rsync / scp. Do you want to do it on a more permanent basis between multiple hosts? NFS / SMB would be the better choice.
 
Nfs or smb would be perfect so i can share beetween various PC for backup redundancy! Any suggestiob on how to.do.it?

Thank you very very much!

Optimal would be a separate server, that all hosts can access independently. This could be a TrueNAS or OpenMediaVault instance, for example. You could also virtualize this, but generally you want this to be separate from the cluster, which is why I recommend getting a separate server as a backup share.

Please be aware that this by itself does not provide backup redundancy - you would have to take additional measure for that on the network share (additional offsite backup to the cloud, RAID/ZFS, ...) depending on your needs

When already buying a dedicated server for backups I would use the Proxmox Backup Server instead of SMB/NFS shares. Way faster, backups only need a fraction of the space and you can set it up for stuff like ransomware protection.
