Explain what timers are in the init systemd system and what role they play?

Timers in systemd are special units that allow you to run services on a schedule or at specific intervals. They replace traditional cron jobs and are integrated into the init system.

Role of timers:

• Automatic start of services at a set time or at regular intervals.
• Management of periodic tasks with flexible configuration.
• Improved control and logging of launched tasks.

Example: you can set up a timer that runs a backup every day at 2 AM.
