rsync

In some respects I'm living in a brave new world of computing convenience these days. I have my external HDD sitting in the corner with the raspberry pi serving it's contents up to the tv, kindle and ipad. Photographs and music (which I never used to backup in any kind of coherent way), I now send to the HDD over scp by SSH or (latterly) ftp from the file manager.

But I want more, dammit! I want the photos and music to be backed up automatically at regular intervals so all I have to do is plonk them in the right local directories and forget about them. I've been aware for a while that rsync might be the way to go about this.

After reading about a bit, making sure rsysnc was present on the pi and laptop, etc:

rsync -r --size-only /home/mitch/Music root@192.168.1.107:/media/Seagate\ Expansion\ Drive/Music

And a similar experiment:

rsync -r --size-only /home/mitch/images/photographs/copy_06_june_2014/ root@192.168.1.107:/media/Seagate\ Expansion\ Drive/Other\ files/photos

Both failed because a new directory was generated:192.168.1.107/media/Seagate. Also, the photos showed up there with a different logo and claimed to have no data when I tried to view.

Looking around this morning, I think I'll need to enclose the paths in single (and double) quotes because of the top answer here.

Assuming that works, I want to demonstrate that nothing will be deleted from the backup drive because it's been deleted on another drive (pretty sure that's OK). Maybe use -a option to preserve the datat for photos? Does that seem likely? Anyway, sort out the photo data loss issue.

Then:

- Figure out exactly what the rsync daemon does
- get cron jobs set up to sync folders on a pre-established schedule
- get data transferring from multiple machines
- get the raspi to "pull" files from the attached machines instead of them "pushing" to the raspi

pdf to png/jpg/etc

Not often I learn something at work that I need to put on here. Anyway, imagemagick: convert -density 600 input_file.pdf output_file.png Gives me a lovely hi-def version of the image. Too hi, probs, but at least it's relatively easy to resize (down) once it's in the appropriate image format.

diskfilter writes are not supported

http://askubuntu.com/questions/468466/why-this-occurs-error-diskfilter-writes-are-not-supported " It's a BUG! This is a bug that occurs in the most recent version of Ubuntu Server (Ubuntu Server 14.04 LTS), when you create the boot partition (or the root partition, when the boot partition doesn't exists) inside a LVM or a RAID partition. You can get more info about this bug in Ubuntu Launchpad: Bug #1274320 "Error: diskfilter writes are not supported" . Why does this bug occur? When the system is booting, GRUB reads ( load_env ) data in /boot/grub/grubenv . This file is called GRUB Environment Block . From the GRUB Manual: It is often useful to be able to remember a small amount of information from one boot to the next. [...] At boot time, the load_env command (see load_env) loads environment variables from it, and the save_env (see save_env) command saves environment variables to it. ...

no sound in Papers Please

No sound at all, actually. First I installed alsa-utils, checked alsamixer master was not muted. Installed pulseaudio and pavucontrol. This gave me sound on youtube but not the game. Eventually found this tip in the hotline miami AUR comments: On x86_64 I had to install lib32-libpulse to get sound working. Without the package there was that error: ALSA lib dlmisc.c:252:(snd1_dlobj_cache_get) Cannot open shared library /usr/lib32/alsa-lib/libasound_module_pcm_pulse.so AL lib: (EE) alsa_open_playback: Could not open playback device 'default': No such device or address   https://wiki.archlinux.org/index.php/Advanced_Linux_Sound_Architecture#Unmuting_the_channels https://aur.archlinux.org/packages/hotlinemiami/
