Re: [OmniOS-discuss] Backup script (one local, multiple remote snapshots)

[Matej Žerovnik]

I did have a look at it during the weekend. Nice tool and easy to use.

It did, for some reason, kept too many snapshots (my retention was 1min=>1min 
on SRC and 1min=>1min,10min=>10min,1h=>1h on DST). What I got was 2 minute’s 
snapshots, 2 10 minutes’s snapshots and 1 hourly snapshot on the DST. Is this 
normal?

Is it possible to not copy the whole dataset/zvol to dataset/zvol but unstead, 
do it like zetaback, copy dataset/zvol to file on dst?

Thanks, Matej

 Does anyone has anything like that implementented? If yes, would be

Re: [OmniOS-discuss] Backup script (one local, multiple remote snapshots)

[Matej Žerovnik]

Hey there,

how come I didn’t find this earlier:)

It does look good after initial testing. I like the option of saving datasets 
and zvols to files instead of zvol on dst system. Better space usage.

Is it possible to run multiple instances of agents on one server? Currently I 
can transfer up to cca 200MB/s with aes128-...@openssh.com 
 cipher and a single connection. I tried running 
multiple SSH connections to backup multiple datasets and I can get up to around 
600MB/s. Is there a way for running multiple instances, each instance taking 
care of its own pool for instance.

+1 for zetaback. There are perhaps hundreds of implementations of this over the 
years. I think you'll find that zetaback is one of the best designs.

Re: [OmniOS-discuss] Backup script (one local, multiple remote snapshots)

[Dale Ghent]

We developed Zetaback for this. As for how you exactly want your snapshots to 
be in number and how long they should stay around, you might be able to 
configure a backup policy which covers that.

https://github.com/omniti-labs/zetaback

The documentation is perdoc within the zetaback script.

[OmniOS-discuss] Backup script (one local, multiple remote snapshots)

[Matej Žerovnik]

Hello,

I would like to implement backup for one of my servers with zfs send/recv. My 
scenario would be the following:

For each dataset:
- keep one daily snapshot on src server
- copy daily snapshot from src server to backup server
- on backup server, I would like to have one daily, one weekly and one monthly 
snapshots

I checked out some ZFS backup scripts I found on GitHub, but non of them did 
that I wanted (znapzend came close, but it keeps too many snapshots for my case)

Does anyone has anything like that implementented? If yes, would be willing to 
share?

Thanks, Matej
