systemd Timers vs Cron: Modern Linux Scheduling

Compare systemd timers and cron: syntax, logging, dependencies, and when to use each for task scheduling.

Why systemd Timers?

• Better logging (journalctl)
• Dependency management
• Runs missed jobs on boot (Persistent=true)
• Resource limits (CPUQuota, MemoryMax)

systemd Timer Example

# /etc/systemd/system/backup.timer\n[Timer]\nOnCalendar=daily\nPersistent=true\n\n[Install]\nWantedBy=timers.target
