Time Machine File System is a read-only virtual filesystem which helps you to read your Apple's time machine backup.

This filesystem does not targets performances, it has been written for a friend who has lost his macbook and wants to recover its data on Linux.

It's actually not perfect, feel free to report bugs or suggestions at [https://github.com/abique/tmfs/issues][https://github.com/abique/tmfs/issues].

Enjoy!

How to use it?
--------------

First you have to mount your HFS partition, by doing something like:

`mount /dev/sdXX /mnt/hfs-root`

Then as root run:

`tmfs /mnt/hfs-root /mnt/tm-root -ouid=$(id -u),gid=$(id -g),allow_other`

Then as a normal user, go to the directory /mnt/tm-root/ and enjoy your data! :-)

Dependancies
------------

 - c++
 - cmake >= 2.8
 - boost >= 1.42.0 (earlier versions may also work, but are untested)
 - fuse

How to build and install it?
----------------------------

Manually, run these commands:

```
mkdir build
cd build
cmake -DCMAKE_INSTALL_PREFIX=/usr/local ..
make
DESTDIR=install-test make install
```

Then if the installation looks ok to you in install-test/ do make install as root with `sudo make install`.

Internals
---------

Time Machine structure:

Snapshot root: `${hfs_root}/Backups.backupdb/${comp_name}/${date}/${disk_name}/`

Hardlink count equals to dir_id: `${hfs_root}/Backups.backupdb/${comp_name}/${date}/${disk_name}/.../Folder`

Real folder with data: `${hfs_root}/.HFS+ Private Directory Data/dir_${dir_id}/`

Our representation:

`/${comp_name}/${date}/${disk_name}/${Real root}`
