How to Creating ISO Files on Linux

Learning how to creating ISO files on linux doesn't have to be complicated. This updated guide presents a clear workflow, practical checks, and troubleshooting advice you can use while completing the process.

1. Create ISO file on Linux via Archive Manager.

On Ubuntu or Gnome, use Archive Manager to create ISO files easily.

Step 1: Open File Manager, select files and folders to backup. Right click, select "Compress".

Step 2: Select .iso, then click "Create" to compress files and folders into ISO.

2. Via command line utility

Dd is a useful command that you can use to create ISO files on Linux. All you need to do is specify the source and destination, and the command will do the work of creating the ISO file.

Use the basic command below:

Dd if=source of=destination

For instance, if you want to mount a CD-ROM drive to '/dev/hdc ', and you want to backup the files and folders in the drive to the file my-cd-backup.iso, you can use the command below:

Dd if=/dev/hdc of=/home/username/my-cd-backup.iso.

The source doesn't have to be the CD-ROM drive. It can be a partition on the same hard drive, an external drive, or a file path, although it doesn't work on folders.

You can also use the mkisofs command to create an ISO file. The advantage of mkisofs is that it gives users many options to customize how they want to create an ISO file.

Use the basic command below:

Mkisofs -o destination-filename source.

For instance, use the following command to back up the Home directory:

Mkisofs -o myHomeBackup.iso /home/username.

You can tell mkisofs to enable the Rockridge extension by setting the -R option:

Mkisofs -R -o myHomeBackup.iso /home/username.

Joliet extensions are enabled with the -J flag:

Mkisofs -J -o myHomeBackup.iso /home/username.

You can also set the partition (-V option) for the ISO file. The partition name will be used as the CD drive letter if you burn the ISO file to a CD.

Mkisofs -V "Home Folder Backup" -o myHomeBackup.iso /home/username.

You can also exclude some files from being added to the ISO file using the ' -m ' option. It supports asterisks (*) so you can use the command as below to exclude all hidden files (file names with a '. ' in front) from being added to the ISO file:

Mkisofs -m ".*" -o destination source.

Check all mkisofs options with the command below:

Mkisofs --help

Although not the best backup option, ISO files will be useful to you in some cases. Above this guide has just guided you how to create ISO files on Linux. Hope the above article will be useful to you. Wish you success.
