In this post, I am using FreeBSD 9.3 but what I do here should have wide application, especially the errors I encounter. I believe in backups. Not just rsync, but multiple copies and in multiple places. RAID is not a backup. rsync is not a backup. The goal of this post is to send a copy of a ZFS filesystem to a remote server. The server in question is already backed up in […]

freebsd-update is a great tool. It reduces my workload. It’s hard to use it wrong, but I have managed to do so. So have other people. Yesterday, three of us encountered the same issue. We did it wrong. We didn’t do it wrong yesterday. We did it wrong months ago, and now it’s come back to haunt us. NOTE if you ever see: Undefined symbol “ssh_explicit_bzero” on a FreeBSD server, you probably have

This is not the first time this has happened. It last happened about a month ago. Tonight it happened for a different reason. This time it wasn’t the size of the mbox (I’m not using mbox on this server). This time it’s the size of the log. $ ls -lha ~/.mailfilter.log* -rw-r–r– 1 dan dan 52k Jan 11 00:18 /usr/home/dan/.mailfilter.log -rw——- 1 dan dan 48M Jan 10 21:03 /usr/home/dan/.mailfilter.log.1 Once I mv‘d the

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’s something to be aware of. Update your PostgreSQL client on your Bacula client if it is used for backing up the Catalog. Ngaios just told me: FILE_AGE WARNING: /usr/backups/bacula/MyCatalog.dump is 45125 seconds old and 0 bytes I looked at the backup job from earlier today: 28-Dec 08:15 bacula-dir JobId 195194: shell command: run BeforeJob “/usr/local/bacula/make_catalog_backup.new MyCatalog” 28-Dec 08:15 bacula-dir JobId 195194: BeforeJob: pg_dump: server version: 9.4.0; pg_dump version: 9.3.5 28-Dec 08:15 bacula-dir

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.

This post has been replaced by a newer one. For reference, the previous post on this server is still available. For future reference, this is the slocum server, which I use for various jails and services. This data was gathered adding increasing the RAM from 16GB to 32GB and adding two SSD to the previous configuration. This is my first ZFS system with more than one pool. Merry Christmas The filesystems, well, some
Backups are useless without restores. I’ve written a few posts about Nagios, my current monitoring tool of choice. Included with Nagios are a number of plugins and you can even write your own plugins. In this post, I’ll show you a shell script I wrote to make sure my backup files turn up where they should, when they should. In my case, these files are database backups, but the idea behind the script

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 my backups there. The source This server contains a Bacula Storage Daemon with access to about 27TB, with
