Maybe I should explain the difference between archiving and compressing (I had to learn this myself as well) …Īn Archive is basically the bundling of a collection of files, which could be just one file as well – there is no compression involved.Ĭompression on the other hand, is the technique to store data in a smaller size than the original data, but does not involve building an archive – it just grabs one single file (chunk of data) and tries to store it in a smaller file.įormats like 7Zip, Zip and Rar combine the creation of an Archive, and after that the Compression of that archive.įormats like BZip2, GZip, LZip, and XZ, are good compression methods, but do not create an archive. tar.xz” (or: “.txz”) is gaining popularity. tar.gz” (or “.tgz”) compression methods are being used on the resulting IMG file to reduce the needed storage space for the backup. Typically, the IMG file format is very well compressible.Ĭommonly the “.

The build in shrink/expand option only works for Linux Ext partitions on a Primary Partitions, and only when your disk uses MBR (Master Boot Record). Note : ApplePi-Baker can optionally shrink (or expand) Linux Ext partitions. You cannot make a backup of your macOS system disk. Note : For backup and restore, ApplePi-Baker only supports non– system disks. This also means that if your disk is 32Gb, even though you may be using only 1 byte, your backup file will still be 32Gb! IMG” file extension.Īs I mentioned IMG file format is a raw copy of every single byte of the source disk, and nothing fancy is being done with it. You can skip this chapter if you’re not all that interested in these details and go straight to “ Installing ApplePi-Baker“.ĪpplePi-Baker is a small macOS utility that allows you to backup or restore disks.Īt its core, it uses the same format as produced by “ dd“, a raw byte-by-byte copy of the disk – typically with the “. This chapter gives you a background on certain aspects of ApplePi-Baker, which may or may not be an interesting read.

Always use TAR when using BZip2, GZip, Lzip or XZ.

Archiving and Compression with ApplePi-Baker.

UPDATE: ApplePi-Baker now also support shrinking and expanding of Linux partitions! – special thanks to Jeff and Mark for testing! I’m not even mentioning the drama when it comes to supporting the different compression formats, signing applications, and 64-bit requirements.Īlmost 2 years later, I proudly present ApplePi-Baker v2. This came with quite a few challenges, especially since Apple increased security for macOS, not allowing me to do certain things straight from my program (see also SMJobBless: Elevated Privileges in Lazarus Pascal).

Besides that, having to enter your “ sudo” password each time was a pain as well, and came with the occasional problems for a small group of users, so that had to go as well.Ībout 2 years ago I decided to rebuild ApplePi-Baker from scratch, no longer using any of the command-line tools. Over time, the use of command-line tools came with some problems thanks Apple for changing command-line tool output with every new version of macOS.

This way, ApplePi-Baker became my personal frontend for command-line tools like “ dd“, “ diskutil“, “ mount” etc. Late 2013, I created ApplePi-Baker for my own use – I just got tired of looking up the proper command-line statements. Users do not just use ApplePi-Baker for this purpose anymore – I have seen users use it for backup and restore of pretty much anything not Raspberry Pi related.

ApplePi-Baker has become well known amongst Raspberry Pi users, with a Mac running macOS, to backup and restore SD-cards.
