sparsebundle-loopback

A FUSE wrapper to present MacOS-style sparsebundle bands as a single file under Linux

Use case:

When using a netatalk server under Linux as a Time Machine device, MacOS will store the device as a sparsebundle. The sparsebundle is implemented as several plists and a directory full of band files.

This FUSE wrapper parses the plists and reconstructs a unified file from the bands and presents it as a single file under the specified mount point.

I currently use it in the following manner to access Time Machine backups from Linux directly. AFP while using the sparsebundle bands is extremely slow over links with limited bandwidth, making using Time Machine directly difficult when traveling.

sparse.py itself depends on libplist: http://cgit.sukimashita.com/libplist.git 

./sparse.py /path/to/<name>.sparsebundle /mnt
losetup /dev/loop# /mnt/<name>.sparsebundle
kpartx -a /dev/loop#
mount -r -t hfsplus /dev/mapper/loop#p2 /mnt2
./tmfs.py /mnt2 /mnt3

/mnt3 will now contain the Time Machine backup file system, with directories named with the dates the backup was taken, each containing the backup from that date.

I anticipate future versions will wrap all of the above steps into one for easier use.
