From time to time, my Bacula – space and time website shows some old jobs that need to be copied to tape. Stuff from 100 days or more. There’s no reason to copy stuff that old to tape. It’s already been copied to tape. So why does it appear? Last night I swapped some tapes […]

Sometimes, you need to restore. But you don’t know when the file changed. Here’s a simple SQL query which shows me that information: And here is the output Based on that output, I want to look at restoring from Jan 13 and before. That’s when the filesize change last changed from 172KB.

I think I’m now at the point where I have all the hardware assembled and it’s ready for testing. Now I’m trying to determine what set of fio tests to run. If you know of a set of standard tests, or just have some of your own, please let me know in the comments. The

This article talks about FreeBSD 8.2 and how device names might change when you add new devices to an existing system. The other day, when I was telling you about the new tape library, one of the important bits was the device names. The existing tape drive was sa0. The new one was sa1. That’s

As recently written, I have acquired a tape library with a 15-tape magazine. It contains a DLT-8000 tape drive which, although it is no longer state-of-the-art, is a step up from the DLT-7000 I am currently using. Today, I will try using this unit for the first time. I’ll do a simple write, try changing

Recently, I rearranged the bottom shelf of my rack and rotated the DEC library 90°. Then I placed a new [to me] Overland DLT MinilibraryXpress (model LXM8115). I plugged the cable from my server into the Overland unit and daisy-chained that to the DEC library. The grey cable which leads up and out of the

Right after getting my SCSI cable problems fixed, I was all set to run some Bacula jobs. They immediately started failing: 27-Nov 12:59 bacula-dir JobId 112458: Start Copying JobId 112458, Job=CopyToTape-Diff.2012-11-27_12.58.05_08 27-Nov 12:59 bacula-dir JobId 112458: Using Device “DTL01” 27-Nov 12:59 kraken-sd JobId 112458: Ready to read from volume “DiffAuto-2357” on device “MegaFile” (/storage/compressed/bacula/volumes). 27-Nov

Last night I powered on my DEC tape library. I had forgotten to power it on earlier in the week after a maintenance session. Backups to tape were queueing up. Bits needed to be moved. Queues needed to be emptied. I powered on. I ran camcontrol rescan followed by camcontrol devlist. The tape library was

As part of my magical Bacula website, I wanted to know when my tape drive required a cleaning tape. It appears that smartctl will reveal this information: [dan@kraken:/usr/home/dan] $ sudo /usr/local/sbin/in/smartctl -d scsi -x /dev/nsa0 Password: smartctl 5.39.1 2010-01-28 r3054 [FreeBSD 8.2-STABLE amd64] (local build) Copyright (C) 2002-10 by Bruce Allen, http://smartmontools.sourceforge.net Device: DEC TZ89

Backups come in three flavors: Full – backup everything Differential – backup everything since the last Full backup Incremental – backup everything since the last backup (Full or Incremental) I took the above from What Is Bacula? Most systems use mtime to determine if a file has changed. Thus, any file that has been modified
