![]() Now you should be able to browse through the files at /mnt/iMac_backup without a problem! Note: if you want to browse the files on the Synology user interface, you’ll probably want to mount it on a location that is already available in the file manager.We recently bought a MacBook Air (M2) for my wife with a more generous internal SSD (1T). ![]() So the last step is to re-mount the partition using tmfs which will make the hardlinks work. You can try to browse through the mounted backup, however you’ll notice that files are likely not accessible because these are stored as hardlinks and these are not supported on hfsprogs by default. Which to me returned /dev/loop1, if it returned something else for you make sure you use the correct loop in the below step. Use the Start position and size as reported by parted for the following: Sector size (logical/physical): 512B/512B Which returns the following output for my backup:ĭisk /mnt/sparsebundle/sparsebundle.dmg: 3221225472000B Parted /mnt/sparsebundle/sparsebundle.dmg unit B print We run parted to find out the start position and size of the HFS data partition. However, the disk image likely holds two partitions (the first being the EFI System Partition), and we only want to mount the partition with the backup data. dmg diskimage (/mnt/sparsebundle/sparsebundle.dmg) that we can mount. You will find the sparsebundle available as a. sparsebundlefs iMac.sparsebundle /mnt/sparsebundle This will allow you to mount the sparsebundle disk image (where iMac.sparsebundle is the name of my backup sparsebundle created by Time Machine on my Synology). The build should result in a binary executable called sparsebundlefs. We will need to add the wheezy main repository for it to be installed.Įdit the file /etc/apt/sources.list to include the following line:Īpt-get install curl build-essential libfuse-dev libfuse2 parted pkg-config tmfsĭownload the latest sparsebundlefs source:Įnter the directory that was created and compile the source code: sparsebundlefs requires fuse-utils which is not included in Debian Jessie as a package, but is included in Debian Wheezy. Next you will need to install the necessary dependencies in the chroot environment (use sudo for all commands to elevate your rights if you are not logged in as root). The first requirement is the Debian Chroot environment see my previous post for instructions on the configuration of this. ![]() This could be useful for others that want to access their Time Machine backup information directly from the Synology NAS side. Next I thought it would be faster to mount the sparsebundle on the Synology and have a instance of Unison go through the files locally while communicating with another instance of Unison on the destination computer.īelow is a write up of how the time machine sparsebundle can be mounted in the Debian Chroot environment of the Synology, using sparsebundlefs and tmfs. Initially I mounted the sparsebundle backup image on the destination computer, unsurprisingly running Unison on this was extremely slow as Unison needed to read the 2TB over a Wifi connection. ![]() And so I was planning to use Unison with a forced direction to get all the latest files from a 2TB backup. Because it was a separate computer I was not able to use the Apple interface easily plus I wasn’t sure what the incremental changes were. In fact, I wanted to only get (unknown) incremental changes from the backup. I have a large Time Machine backup on my Synology NAS and wanted to restore files from it to a computer other than the source of the backup.
