backup migrating

[festa]

Hello I m using proxmox cluster with 3 servers in it, and i want to move backups between storages in different servers but in the same cluster. Maybe someone knows how to backup vm to another server storage. I also do not use proxmox backup server

the backup archives for regular vzdump are just (vma/tar) files, you can copy them using scp or rsync..

 

[basil]

you can use NFS and create storage from one node to other

but if I need identical storage on all three nodes, I use glasterfs with replica 3.

I Use this schema for backup and sharing iso's in cluster


gluster peer probe pve21; gluster peer probe pve22; gluster peer probe pve23

create same on all nodes:
zfs create -p rpool/gluster/gluster-backup
zfs create -p rpool/gluster/gluster-storage
zfs create -p rpool/gluster/gluster-iso

gluster volume create gluster-iso replica 3 {pve21,pve22,pve23}:/rpool/gluster/gluster-iso/brick force
gluster volume set gluster-iso features.trash off
gluster volume set gluster-iso performance.write-behind off
gluster volume set gluster-iso auth.allow pve21,pve22,pve23
gluster volume start gluster-iso

gluster volume create gluster-backup replica 3 {pve21,pve22,pve23}:/rpool/gluster/gluster-backup/brick force
gluster volume set gluster-backup features.trash off
gluster volume set gluster-backup performance.write-behind off
gluster volume set gluster-backup auth.allow pve21,pve22,pve23
gluster volume start gluster-backup

gluster volume create gluster-storage replica 3 {pve21,pve22,pve23}:/rpool/gluster/gluster-storage/brick force
gluster volume set gluster-storage features.trash off
gluster volume set gluster-storage performance.write-behind off
gluster volume set gluster-storage auth.allow pve21,pve22,pve23
gluster volume start gluster-storage


And add GlusterFS storages server localhost
gluster-iso
gluster-backup
gluster-storage
