Bacula restore using a regex

Leave a Comment / Backups, Bacula / By /

Short version: I used this regex when restoring to a jail on the slocum server: !/\.zfs/snapshot/snapshot-for-backup/!/! Background Today I did this when setting up an ssh-key on a new host: ssh-add -L > ~/.ssh/authorized_keys Oh. That should have been >>. Restoring During the Bacula restore, I need to change this path: /usr/jails/mydev/.zfs/snapshot/snapshot-for-backup/usr/home/dan/.ssh/ to /usr/jails/mydev/usr/home/dan/.ssh/ That is, I need to remove this from the path: .zfs/snapshot/snapshot-for-backup For background on this backup strategy using jails, […]

Older versions of Bacula – copy/migrate has limit of 99 jobs

Leave a Comment / Backups, Bacula / By /

Last night I started to catch up on copying jobs from disk to tape. There were about 420 incremental jobs waiting. I started my CopyToTape-Inc job, and it queued up 417 jobs: The next morning, all jobs had completed, but there were still jobs left to be copied over (as determined by my magical Bacula portal). I ran the job again. Let them finish. Still more jobs left to job. I talked on

Backup speed

Leave a Comment / Backups / By /

It’s little things like this which improve the copying of backups to tape. Speed. Each of those Volumes are 5GB in size. The tape drive takes about about 2-4 minutes per 5GB to write it to tape. Between the end of IncrAuto-4150 and the end of IncrAuto-1455, the tape drive wrote 20GB in about 9 minutes. That’s roughly 2GB/minute or about 37MB/s.

Using the Compaq Storage Works MSL5026 Library

Leave a Comment / Backups, Bacula, FreeBSD, Open Source / By /

I am fortunate to receive donations. In the early days, it was a 386 desktop. Later, it was SCSI drives. Recently, it’s been tape libraries. A Bacula user in Europe donated an Overland DLT-8000 tape library in 2012 and paid for shipping to me. At BSDCan 2013, I was fortunate to pick up an Compaq StorageWorks MSL5026 SDLT tape library and it has sat unused. It’s dead Jim A few weeks back, the

Looking for a tape library

4 Comments / Backups / By /

The current situation The tape library I am using now is a DLT-8000 with a 15-cartridge magazine. Until a few weeks ago, it’s been quite reliable. But now, the drive inside it is not performing well. It’s throwing drive faults and failing to write everything to the tape (i.e. what we read back is smaller than what we wrote). I have two replacement DLT-8000 drives and I’ve tried both. Neither of them are

Script for listing the latest ZFS snapshot – starting place for Bacula backups

Leave a Comment / Backups, Bacula, ezjail, FreeBSD, Jails, ZFS / By /

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, and I’m going to list two: data integrity snapshots In this case, instead of backing up the entire

Bacula – client changes host name

2 Comments / Backups, Bacula, Open Source / By /

Like many people, I have a laptop which I backup using Bacula. In my case, the laptop may be present under one of two condition: directly connected to my network via wireless indirectly connected to my network via VPN My VPN of preference is OpenVPN, but that’s not relevant to the situation. The issue is: the IP address for my laptop changes depending upon which of the two connections it is using. Putting

Adding a tape library to Bacula

Leave a Comment / Backups, Bacula, Open Source / By /

This article was written some months go, but only published today. I recently acquired a new tape auto-changer / library. I have already run some simple tests on the library, and all seems well. I already have an existing Bacula installation and my plan is to add this new auto-changer into that. The Devices The following is a list of the devices associated with my auto-changer. The output has been trimmed to exclude

ezjail-jail: making a full backup of a FreeBSD jail with Bacula

Leave a Comment / Backups, Bacula, ezjail, FreeBSD, Jails / By /

I’ve been using Bacula since early 2004. I’ve been using FreeBSD since 1998. Jails are a relatively newcomer. I starting using it later in 2004. But it’s only recently that I’ve started using them intensively. Backups are always a touchy subject. With ezjail, the files you need to backup are greatly reduced. You’re not backing up the base OS, just the local files. I’ve created a fileset which seems to do the right
