This is an easy one (well, maybe).
Recent versions of ZoL (zfs on linux) have added the previously-missing zfs send | receive option to send a pool with its compression intact. That is to say, send the data in its compressed state. This is the zfs send -c option.
I am currently using pve-zsync to send a nearly 2 TB dataset from one machine to another (for backup), the source is gzip-9 and the destination pool is created under a gzip-9 pool (so that should be inherited), but unfortunately the operation is decompressing the files on the sender and re-compressing them on the receiver (with the expected slow performance maxing out cpu on receiver).
In testing I was able to do the operation and keep compression like:
zfs send -p -c pool1/archives@now | zfs receive -v -s -u pool2/newbackup
Can you implement the -c option in pve-zsync? If not always, just for initial replication run?
In the mean time, if I did the send | receive using my options, then deleted the snapshots, can a pve-zsync job be made to do incremental update jobs from that starting point, or does it need to do the initial transfer also?
Thanks.
