Backup with Remastersys
What is Remastersys?
Remastersys is a program for making backup and even distributable iso files for your Linux system. It is used to create the iso files for Bodhi Linux and is included on every system by default.
Why use Remastersys?
If you would like to create a backup of your Bodhi Linux setup, Remastersys is definitely one way to do it. It creates an iso file that you can install on your computer or another one, should something go wrong or you simply want to move to another computer.
With that said, Remastersys can be useful for installing the same setup on multiple computers like one might do for a classroom. Set up one computer however you like, make an iso with Remastersys, and then install your custom Bodhi on the other machines.
Each install works just like the original Bodhi install, allowing you to change the username, password, and computer name.
Important Remastersys Requirement
If you are using the kernel that came with your Bodhi Linux installation, which comes with AUFS support, you should be fine. However, if you have upgraded your kernel, you should install the package unionfs-fuse.
This is important: If you do not have either AUFS support or unionfs-fuse installed, your iso will not run. You will create a backup that does not work.
Bodhi Linux’s kernel does not update automatically, which helps to prevent this problem.
Here is what you want to do to use Remastersys.
Step 1: Clean Up Your System
It’s definitely optional, but using Bleachbit or another cleaning program prior to running Remastersys will make the process faster and the backup smaller, at least to some extent.
Step 2: Close Everything
Close up any programs you have open. Browsers, documents, all of it.
Step 3: eSudo
Open eSudo, either by Running Everything or under Applications > System Tools > eSudo.
In the box marked “Command”, enter remastersys-gtk and enter your password in the second box. Hit OK.
Step 4: Settings
Once Remastersys actually pops up, you may get a little window reminding you to close up everything in case you haven’t already. Double check and hit OK.
Optionally, you can go to the Settings tab and make any adjustments necessary.
- Username – The username at loading the iso. This name can be changed when the iso is installed.
- CD Label – The name given to the disc or flash drive the iso is put onto.
- Filename – The name of the iso file itself. Changing the filename may be helpful to keep track of multiple iso files.
- Working directory – Where Remastersys will do its work and put the backup.
- Files to exclude – What you don’t want to backup. For instance, if you don’t want to backup your Pictures and Videos folders, you would put
With “username” as your actual username, of course.
- Show install icon on Backup mode desktop – If checked, allows you to install from a backup iso.
If you don’t touch any of the default settings, (which were used to create the Bodhi iso you’re using) you should be fine.
However, it should be noted that if you do not have enough space for your backup, you won’t be able to make the backup. You could change your working directory to that of an outside storage device, such as a portable hard drive.
Step 5: Backup
Go to the Actions tab. Hit Backup.
How long this process takes depends on just how much is being backed up and the speed of the computer. Do not use the computer until Remastersys has finished backing up.
Step 6: Getting the Backup
The backup is located in the working directory.
If you left it as /home/remastersys, you’ll find it there. This does not mean it is in your personal home folder, where you find your Pictures and other folders of yours. That is technically /home/username, so you just need to go up one more directory (into /home) to get to it.
You’ll find the iso file, which uses the name that was set for it in the Settings tab previously. You’ll also find the md5 file for it, allowing you to be able to check the md5sum of the iso as you transfer it to other places.
Using the Backup
The created iso file should work the same way as the Bodhi iso you originally used, except that it has everything you backed up on it.
Isn’t Remastersys Outdated?
It is occasionally suggested that, since Remastersys is no longer being maintained and updated, that Bodhi Linux should not recommend people to use it.
As the old saying goes, “If it ain’t broke, don’t fix it.” Remastersys works. Remastersys is used to create the iso files for Bodhi Linux itself. As Bodhi Linux is about user choice, you are free to choose an alternative, despite Remastersys being already included in every install.
