This post has it all: backups deduplication snapshots ZFS Bacula ezjail Backups are essential for proper sanity, or at least, a reasonable facsimile.

This is zuul, the server I’ve been setting up to be a new jail host. I like to store away this type of documentation, in case I need it later. The partitions: The ZFS file systems: The ada0 drive details: And ada1 drive details: And finally, dmesg:
I have an exciting project ahead of me. I will soon be configuring a new server. It will be ZFSROOT running a pair of mirrored 500GB disks. I plan to use a configuration tool for management of this server. The final choice of tools is yet to be decided. The services provided by this server

FreeBSD now has zl4 compression for ZFS. But you must upgrade your pools to get it. If you try before upgrading, you’ll get: # zfs create -o recordsize=8k -o primarycache=metadata -o compress=lz4 system/usr/home/dan/pgsqlsql cannot create ‘system/usr/home/dan/pgsql’: pool must be upgraded to set this property or value So, let’s upgrade: # zpool upgrade -a This system

For future reference, this is the knew server. It runs a few jails, including Bacula regression testing services. The filesytems:
This post has been replaced by a newer one. For future reference, this is the slocum server, which I use for various jails and services:
After the zfs send, I had system/foo/bar, but I really just wanted system/bar. How do I fix that? mv(1) was my first guess. I was wrong. What I wanted was zfs(8) rename. Let me explain. After doing my: zfs send storage/compressed/bacula@2013.07.22:06:33 | mbuffer | ssh -t dan@10.5.0.20 ‘zfs receive system/usr/local/bacula/FromKraken’ I quite, correctly, wound up

Today it finished. That ZFS send I started on Monday finally finished. Recap The original command was: # zfs send storage/compressed/bacula@2013.07.22:06:33 | mbuffer | ssh -t dan@10.5.0.20 ‘zfs receive system/usr/local/bacula/FromKraken’ That’s was the initial send of the filesystem. But more data has been added to it. So I take another snapshot, and send that: Send
