# zsync
|
|
|
|
ZFS replication script by Thorsten Spille <thorsten@spille-edv.de>
|
|
- replicates ZFS filesystems/volumes with user parameter bashclub:zsync (or custom name) configured
|
|
- creates optional snapshot before replication (required zfs-auto-znapshot)
|
|
- parameter setting uses zfs hierarchy on source
|
|
- mirrored replication with existing snapshots (filtered by snapshot_filter)
|
|
- pull/local replication only
|
|
- auto creates full path on target pool, enforce com.sun:auto-snapshot=false, inherits mountpoint and sets canmount=noauto
|
|
- raw replication
|
|
- tested on Proxmox VE 7.x/8.x
|
|
- ssh cipher auto selection
|
