Some of the files that appear to be zrepl packages are not packages at
all.  For example, the solaris and illumos downloads are just single
binaries that run on those platforms.  They are components of
packages, not complete packages.

Repology gives users the ability to see which distro repos have a package
without having to manually query them all. It's been really useful for me
in determining whether/which distros meet my needs.

If you click through the znapzend link in my previous email you'll see the
OI repo listed there. You can even click through to see where the
information is coming from

That's not very important, because:

# pkg list -afv | egrep "znapzend|zrepl" | cut -d" " -f1
pkg://openindiana.org/backup/znapzend@0.20.0-2020.0.1.0:20210518T144819Z

Yes, this was a surprise to me too, hahaha.

ZnapZend and zrepl are actually very similar in function: they both do
replication of ZFS filesystems.  I wondered at first that these two
backup systems had no facilites for restores, like you get with a
traditional backup system.  However, I soon realized that if you had a
replica, you could just copy a file to restore it.  Alternatively, you
could recreate an entire filesystem from a replica.

The system I used formerly, zetaback, only stored "zfs send" streams on
the backup device.  That's something that's failure-prone, according to
all the ZFS documents I've read.

The only disadvantage of zrepl that I've encountered so far is that it
does not have an OI package.

You may wish to investigate "zrepl" as well, which has some neat features:

Thanks for the response, and sorry for the delay in my response.
That may be easy, but it's not really what I wanted.  I'd prefer
something that ran on my existing backup server.

Ah, that sounds promising.  I'll investigate further, but it may be
exactly what I wanted.  I see that ZnapZend already has an OI package,
making it easy to install.

I had been using zetaback, from OmniTI.  It also has an OI package.
I may continue to use that product.

I assume you know there are gazillion ways to implement this, but if you
want an out of the box ZFS solution I'd say the *easiest* (note the
emphasis) option is either a TrueNAS Server
 or a BYOD/DIY TrueNAS Core
 system.

Please search the following phrases in Google one by one :


zfs backup strategy
zfs proxmox backup server
zfs backup server


( "in Google" because we will see  similar result lists . )


During such searches , you may encounter more search phrases
suitable for your needs .


Personally I am completely ignorant of the ZFS system and its handling .


With my best wishes ,

[OpenIndiana-discuss] Backup for ZFS filesystems

[Gary Mills]

I'm looking for a backup system that uses ZFS facilities to integrate
backup with ZFS.  Is there such a thing?

In addition, I'm looking for something that stores the backups on a
single backup server, with network connections to multiple backup
clients.  Of course, I would also like easy restores to ZFS
filesystems.

What are you using to backup ZFS files?
