try on your machine
The command "tlmgr backup --all" is used in TeX Live, which is a comprehensive distribution of the TeX typesetting system.
The command performs a backup of all installed packages and files managed by tlmgr, the TeX Live package manager.
Here's a breakdown of what each component of the command does:
- "tlmgr" refers to the TeX Live package manager. It is a command-line tool used to manage packages in TeX Live.
- "backup" is a subcommand of tlmgr used to perform backups of the TeX Live installation.
- "--all" is an option that instructs tlmgr to backup all installed packages and files.
When you run this command, tlmgr will create a backup file that contains a snapshot of the current state of your TeX Live installation. This backup can come in handy if you need to restore your TeX Live setup to a previous state, or if you want to transfer your TeX Live installation to another system.
