Using Mac OS X 10.7 (Build 11A511), attempts to backup volume content with Time Machine have failed.
With a simple non-encrypted image I tried three approaches:
- the traditional workaround, which reportedly works on Snow Leopard
- (1) and (2) combined.
This leaves the question:
How can Time Machine backup .sparsebundle volume content?
- content of the volume, not the bands of the image.
Differences between Snow Leopard and Lion
Within this file, the
FXRecentFolders key contains an array of data.
Opening the required volume in Finder, then closing the window causes volume-related data to be written as a sub-key:
file-datasub-keys in Snow Leopard
file-bookmarksub-keys in Lion.
Time Machine preferences
removeexclusion verb of tmutil (manual page not yet published by Apple):
- seems to add — to the
com.apple.TimeMachine.plist— key data that differs from the data found in
- does not add a corresponding key string to the
For a volume named myVolume
defaults read com.apple.finder FXRecentFolders | grep --before-context=1 myVolume
diskutil information /Volumes/myVolume | grep UUID
A similar question, asked in 2010
- that 2010 question focuses on FileVault 1 encrypted home directories in Snow Leopard
- this 2011 question, not focused on FileVault, is more broadly about content of volumes attached from sparse bundle disk images in Lion.
