Full disclosure: I’m biased. I like the combination of PostgreSQL, FreeBSD, ZFS, and Bacula. In fact, I like it so much, I wrote the PostgreSQL backend for Bacula. Since then, I have been using Bacula for over 10 years. I have backed up to HDD, DDS, DLT, and SDLT. Bacula has proven to be reliable […]

Here is the output for zfs-stats on slocum. This represents a 24 hour period. This server acts as my database server (MySQL and PostgreSQL), and runs bacula-dir, but does not store any backups locally. It also houses the dev copy of FreshPorts.

Here is the output for zfs-stats on knew. This represents a 24 hour period. This server receives backups (via bacula-sd) and runs regression testing in various jails for the Bacula project. As a little side venture, it also loads up each of my backed-up databases.

NOTE: when upgrading a zpool, it may be necessary to also upgrade the bootcode for that disk (or disks). Be aware of this before proceeding. I know I have missed this step more at least once. Earlier today I was adding a new pool to the system. After creating the pool, the status showed this:

I haven’t tested this yet, but I’ve installed the hardware. The real test will come after a reboot and actual use of the new drives. NOTE: Although this claims to be creating a new ZIL (SLOG) do not believe it. In fact, stop reading right here. There is nothing of use below. What will they

It seems that when I decided to send a filesystem from one server to another, I neglected to establish sufficient space existed. This morning, before I headed to BSDCan, I found that my server was very sluggish and slow to respond. Nagios was flagging all kinds of errors, some of which I’d never seen before.

I have two ZFS servers which have several TB of space. One of the great ZFS features is the ability to send one filesystem to another filesystem, on the current or another server. I will do this over ssh. One of my servers has a lot of spare space, so I figure I will duplicate

Today I will be installing ezjail 3.3 on a FreeBSD 9.2 system. I will give an overview of the installation and go straight to the configuration of the first jail. As I type this, I’m looking back at my old notes from 2008. Installation I installed ezjail with this command: pkg install ezjail Configuration Enable

This post has it all: backups deduplication snapshots ZFS Bacula ezjail Backups are essential for proper sanity, or at least, a reasonable facsimile. I strongly believe that doing backups right is the only way to backup. Go big or go home. I’ve been converting all my servers to ZFS. I like ZFS for many reasons,
