Time Machine backup of legacy filevault encrypted homedir? I have recently upgraded from Snow Leopard to Mountain Lion. Given that I don't have a lot of space left on disk, it was not feasible to migrate from Filevault to Filevault 2. 
I have just noticed today that Time Machine seems to ignore my homedir sparsebundle in its backups. On Snow Leopard, it would back it up when I logged out. Now it does not do that anymore, and so I don't have any backup of my homedir since the migration to Mountain Lion. Does anyone have any ideas on how this can be fixed or worked around?
I haven't tested this on 10.8.4, but here's how I used to work around this.


Make a second account that exists only for you to be able to log out completely of your main account.
Log into the second account only.
Start a backup so that the legacy file vault files can be backed up.


Basically, Time Machine doesn't run unless someone is logged in.
