Hi,
while I highly recommend PBS I made good experience with using CIFS
instead of NFS for performing backups to a central NAS.

hi Alex
in case you have a limited budget now
you may do backups local backups but it is not recommended by some
cheap NAS ASAP
temporal solution:
1. create some filesystem LVM/ext4 @node1 and mount at /mnt/backup
2. install NFS server @node1 and export /mnt/backup to node2
3. install NFS client @node2 and create mountpoint /mnt/backup
4. edit fstab @node2 example
node1:/mnt/backup /mnt/backup nfs
defaults,noatime,bg 0 2
5. mount /mnt/backup
6. add directory to your proxmox storage via webGUI
or add to /etc/pve/storage.cfg example
dir: backup
path /mnt/backup
content vztmpl,backup,iso
after this you will have backups accessible at both nodes
hope it will help you

Hi all,
I have setup a dual server setup, with latest proxmox v7.x. Each host
with
its own local storage. No shared storage (CEPH, GlusterFS).
I understand I can have VMs hosted on top LVM with qcow2 disk images
or on
top thin LVM as raw thin LVM volumes. On both cases I still keep the
option
to be able to perform VM backups. Which one is the preferred way
according
to your experience? I will try to do some quick tests on the IO
performance
between the two.
Also, I was thinking to replicate the VMs from one host to the other.
I
understand that for the Proxmox integrated replication feature I need
ZFS
backed storage. As I am not much into ZFS, although I really enjoy
FreeNAS
and its great features and will definitely look into it later, I was
thinking to prepare a custom script that would snapshot the LVM
volumes
where the VM images reside and sync the VM disks from one host to the
other, using rsync, just for a local copy of them. Of course I will
take
care to have an external media also to periodically export the VMs for
backup purposes, though I would like to have a local copy of the VM
disk
images at the other host, readily available in case I face issues with
the
external media or one of the hosts. What do you think about this
approach?
Am I missing some other feature or better approach?
Regrading the sync/replication of the VMs between the hosts (without
ZFS),
I was thinking also to have a dedicated local LVM volume for these
periodic
backup jobs configured within Proxmox and then the custom script to
just
rsync these backup images between the two hosts. This seems a simple
one
though it increases the storage requirements, while with the previous
approach with the custom script, the script would snapshot, sync to
the
other side and remove the snapshot without keeping a redundant local
copy
of the disk image in the same host.
Sorry for the long read.
Appreciate any feedback.
Alex
