Backups with Bacula
by Tony Fernandez 31 Oct '18

31 Oct '18

Hi All, I just recently joined your group and was hoping for some insight or advise on building a backup solution. My question is related to Bacula on FreeNAS. I hope it's ok that I ask if not I understand. ==Background== We run a mixed environment (Windows and Linux). I've been slowly moving services that we run over to Linux wherever possible however I've run into an issue with our existing backup server. It is a Microsoft product. I'm not looking for help on it, instead I am looking for advise on using bacula. I've configured Bacula and have it working successfully and I like how I can deploy agents onto my servers to handle backups. I love the distributed achitecture. So my question: I'd like to use FreeNAS as our StorageDaemon (sd) going forward. I'd also like to do remote offsite backups by either rsyncing files over to a remote server or by getting FreeNAS to backup to an external HDD that I rotate weekly. ==Questions== Does anyone see any issues with this? What do you think about the HDD rotation? Thanks, Tony

USB-C port was Aging Dell monitor (U3011)

I've switched out the ThinkPad for a T480, which has *no* DisplayPort connector but brings back HDMI (lower resolution with the Dell monitor) and forces me to spend seventy bucks on a new cable (USB-C to DisplayPort). After the screen blanks, the monitor refuses to wake up. Sometimes, corrupt images (very gradually) appear in bands. When the monitor is asleep, Fedora thinks it's still there and leaves open windows on it, completely inaccessible. Powering it off and on does nothing, and it needs to be unplugged/reconnected. Am I missing a BIOS setting? (There were many that needed to be set initially.) Is this a driver problem or should I file a bug? Happens on Xorg and Wayland. Mike

Practical Use of GRUB's DSL: With the examples inexplicably left out of the GRUB documentation
by Giles Orr 16 Oct '18

16 Oct '18

I've finally released a document I've been working on for a while: "Practical Use of GRUB's DSL: With the examples inexplicably left out of the GRUB documentation" ( https://www.gilesorr.com/grubdsl/ ) Daniel did the editing, and set me on this path in the first place with his own interest in GRUB. The GRUB DSL is somewhat similar to an older version of a Linux shell, but documentation of its functionality online is poor to non-existent. Don't get me wrong: GRUB has a lot of documentation of individual commands, but how you can assemble them into useful scripts is barely documented at all. (Yup, its an uncommon application realm.) My greatest frustration with GRUB's DSL is the lack of redirection and pipes (I understand why they're not there - but it would be nice to have them). I hope this is helpful to someone! ----- As a technical side note, I learned the basics of LaTeX in an attempt to create this document in that language (I'd been wanting to learn it for years). LaTeX is supposed to be able to generate not only PostScript and PDF, but also HTML. But it turns out the HTML generator isn't nearly as well maintained as the PDF generator, and in the end I could find no way to implement my code examples in such a way that the HTML generator wouldn't fail on them. I also found the language unnecessarily complex for what I was trying to achieve and ultimately switched to raw HTML (which you see above). LaTeX may have been a poor choice. :-) -- Giles https://www.gilesorr.com/ gilesorr(a)gmail.com

[GTALUG-Announce] Special Event: Seatbelts and Airbags for Bash w/ Michael Potter
by hi＠gtalug.org 16 Oct '18

16 Oct '18

# Special Event: Seatbelts and Airbags for Bash w/ Michael Potter https://www.eventbrite.ca/e/seatbelts-and-airbags-for-bash-tickets-51177497… ## Date and Time Wed, 17 October 2018 6:45 PM – 9:00 PM EDT # Location Hacklab.TO 1266 Queen Street West Suite #6 Toronto, Ontario M6K 1L3 # Abstract: This presentation will focus on the underutilized features of bash that are critical to building production quality scripts. Demos will show you how to turn on options and error trapping that expose the hidden time bombs in the code. Turning these features on should be considered a requirement, much like turning on “strict” and “warnings” is considered a requirement for Perl programs. Also, as much of the bash syntax has become outdated, the presentation will explain which syntax is best to use and which syntax to avoid. Knowledge of any of the common UNIX scripting languages will be sufficient to understand the presentation and script authors at all proficiency levels should find value in attending. Although the presentation does not address differences between Korn shell and bash, much of what will be discussed also applies to Korn shell. # Bio: Michael Potter is a long time UNIX user and C developer and more recently a consultant to insurance companies. He is a proponent of strongly typed languages which inspired him to try to "fix" bash by using its underutilized features to make it more reliable. Please arrive early to be seated, presentation will start at 7pm sharp. --- GTALUG Announce mailing list announce(a)gtalug.org https://gtalug.org/mailman/listinfo/announce
