Time Machine on Mac OS 10.6.8 failing backing up to an Ubuntu netatalk server with "(Error) IndexSDB in si_writeBackDBO:Error 2 storing dbo"

I ran into some problems about four months ago with being able to back up my 10.6 Mac to an Ubuntu netatalk server. I just started failing, with a generic error message on the UI. All other netatalk services and shares were working fine.

It was getting to the point where it looked like it was working, but once it actually began backing up, it would get to about 100kb, and then fail with this message in the system log on the Mac:

Oct 29 16:37:48 my-macbook mds[38]:
(/Volumes/Backup of MyMac/.Spotlight-V100/Store-V1/Stores/XXX-XXX-XXX-XXX-XXX)
(Error) IndexSDB in si_writeBackDBO:Error 2 storing dbo(9770a3,430,182,4b076d10a69e9,0,1d1686,0)

I was able to follow the instructions copied below from a comment on this page:

10.6: Set up Time Machine on networked AFP volume

Obviously I didn't follow them exactly, since I have an Ubuntu server and not a Mac OSX server, but it now turns out that my Mac now creates the sparsebundle file for me! I basically deleted the whole folder (sparsebundle that I had created for the previous version of Mac OS) that I was using for the netatalk share, created an empty one with 777 perms, added the .com.apple.timemachine.supported file, and my Mac did the rest!

Note: The backup did fail once or twice after following these instructions, the third time it started working all by itself, all I did was retry.

10.6: Set up Time Machine on networked AFP volume
Authored by: Henk Poley on Feb 27, '11 01:52:53AM

Maybe I'm doing something wrong.. but the only thing I have to do is:

1. Create an AFP share on an OS X machine (set permissions, user accounts & passwords as you like)
2. Run `touch .com.apple.timemachine.supported` from Terminal.app on that share
3. Mount the AFP share by clicking around in Finder
4. Point Time Machine to the disk

It then goes off to create a .sparsebundle, mounts that and does a backup.

I may have run the magic `defaults write com.apple.systempreferences TMShowUnsupportedNetworkVolumes 1` way back when, so you may have to run that too.

Both machines run 10.6.6, but I (maybe miss-)remember doing it like that on Leopard too.

(Before anyone says this doesn't work anymore, I'm doing an initial backup using that method right now)

How to set chrome as your default browser for Thunderbird on Ubuntu

From this bug report:

it appears that in Thunderbird 3 the protocol handlers are ignored in favor of the
settings in the "Attachment" preferences. Indeed, once I set the http and https
"content types" to xdg-open, Thunderbird correctly opened http and https links in
Chrome.

Getting jruby running with mysql on ubuntu

You want to get jruby running quickly on ubuntu using mysql as a backing store?

Unfortunately, it does not "just work" with sqlite3 out of the box on ubuntu for some reason. I don't really care why, as mysql is very easy to setup. The most important step that flexed my googling muscles was setting the database adapter to jdbcmysql in the database.yml file.

I will post later on a howto to get this working with glassfish and war files. For some reason, warbler nor goldspike "just work" on ubuntu either.

sudo apt-get install mysql-server mysql-client libhtml-template-perl mailx dbishell libcompress-zlib-perl mysql-doc-5.0 tinyca

Adding subversion to eclipse on linux (ubuntu)

You want to use subversion in eclipse? You will need a javahl implementation.
