Hi,
I wonder if I can backup with timemachine the contentes of a mounted dmg image?
My idea is to have a truecrypt volume and backup its contents. Using filevault with timemachine is not as
easy and simple as I was thinking.
So, if I can modify timemachine to backup any mounted image in /Volumes/, that would solve my problems.
Many thanks

If the disc image is encrypted, then no. TM knows not to backup encrypted data that is in the clear when the image file is mounted. However, it will backup the entire disc image when it is not mounted. This works similarly to how it does in FileVault.
Thanks for the reply.
Is there a way to backup any mounted image? Encrypted or not?
I would later exclude the .dmg file from timemachine. But I want TM to backup the contents. Currently TM will backup USB hard drives formated as HFS, but not a mounted .dmg image formated as HFS+

Yes, as long as a mounted device is not excluded. TM should backup any mounted device that isn't excluded.
If you backup the data you want encrypted using TM, then that data are no longer secure. Sort of obviates the point of an encrypted disc image.
I've never experimented with this myself, but I suppose TM may be programmed to ignore mounted disc images and only backup the image file itself whether or not it's encrypted.
I'm backing up my 10.6 system over AFS to a 10.7 system. The volume on 10.7 containing the backups is encrypted with FileVault2.
On my 10.6 system an encrypted dmg is mounted as volume xyz.
Problem is that Time Machine won't back up xyz.
Is there a way to coax 10.6 Time Machine into backing up xyz?
"TM knows not to backup encrypted data that is in the clear when the image file is mounted. However, it will backup the entire disc image when it is not mounted."
But is there a way to force Time Machine to do it anyway, that is the question!
Hi guys, I have kind of similiar problem, only in my configuration there is no TC volume, whole partition was encrypted using TrueCrypt. Does anyone know the way to back up data stored on this drive with TM? BTW I understand the security issues and it's kind of cool that TM recognize encrypted volume and does not copy it's contents when its in the clear but ... shouldn't it also recognize whether my TimeCapsule is encrypted? In my case it is so it should work just fine.
Off topic - I only use TrueCrypt because once I enter password to encrypted HFS+ non system partition in Mac OS X Lion it's always avalaible to everyone, even if I unmount it, it's still unlocked, no password required to mount it again. Only way I found to lock the drive again was to shut down the system. Is there any other solution?
Thanks,

Timemachine and mounted .dmg images?
