After some weeks of using TeamDrive I felt that I have to get another solution for syncing. TeamDrive isn’t bad, but it isn’t good either. It works most of the time, say 95%. But syncing is a matter of 100% trust, so I can’t live with crashes or “oh, I’ll sync in a few minutes, perhaps”.

So I decided to give unison and OS X “Folder Action” a try. But those don’t have a “on file change” event and reading about it many user complain that they aren’t really reliable. So that wouldn’t be better that TeamDrive.

Than launchd came in my head. I remembered the magic with the ssh-keys and thought: Hey, use a launchd FSEvent and combine it with unison – that’s it! Read some doc and finally: All you need is a little plist like this:

1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

<plist version="1.0">

<dict>

   <key>Label</key>

   <string>de.dlite.unison</string>

   <key>OnDemand</key>

   <true/>

   <key>Program</key>

   <string>/Users/joedoe/bin/unison.sh</string>

   <key>WatchPaths</key>

   <array>

   <string>/Users/joedoe/Library/Things</string>

   </array>

</dict>

</plist>

Than add it to launchd via

launchctl load ~/Library/LaunchAgents/de.dlite.unison.plist

and here we go: Saving a file, creating a new one or deleting an old one always delivers a fine call of my unison-script which syncs with my own server. 🙂
