Timeshift
Timeshift is a Linux system restore tool and recovery utility designed to revert an operating system to a previous known-good state. It functions as both a BTRFS snapshot manager, utilizing atomic subvolumes for rapid recovery, and an rsync-based backup tool that creates incremental snapshots of system files and settings using hard links.
The utility supports system state reversion from within a running environment or via an offline boot medium. It includes the ability to rebuild the bootloader during restore processes and can perform cross-distribution restoration to reinstall a previous system state even after a different operating system has been installed on the root partition.
The project covers automated system backups through a timetable-based scheduling engine and manages the retention of daily, weekly, and monthly versions. Additional capabilities include the use of exclusion filters to omit volatile data from snapshots and the execution of custom automation scripts following a system restore.
Features
- Operating System Restores - Returns a Linux operating system to a previous known-good state after failed updates or configuration errors.
- Automated Backup Systems - Schedules regular incremental backups of system files and settings to maintain a history of recoverable versions.
- System State Reversions - Restores the operating system to a previous snapshot either from within the running environment or via an offline medium.
- File System Incremental Backups - Creates incremental snapshots using rsync and hard links to minimize disk space usage.
- Snapshot and Subvolume Management - Uses BTRFS atomic copy-on-write subvolumes for near-instantaneous system state capture and restoration.
- System Recovery Utilities - Restores bootloaders and system states from within a running environment or via a live boot medium.
- Backup & Disaster Recovery - Restores a bootable operating system and bootloader from a live USB when the primary system cannot start.
- System Restoration - Bootstraps a minimal environment to mount target partitions and restore system files without a running host OS.
- System Data Backup Schedules - Provides a timetable-based system for creating automatic snapshots and managing retention periods.
- Cron Scheduling - Triggers automated snapshot sequences using system timers to maintain a rotating history of backups.
- Bootloader Recoveries - Rebuilds the GRUB bootloader during the restore process to ensure the system remains bootable.
- Configuration Version Snapshots - Saves snapshots of the root filesystem before risky changes to enable quick reversion of system configurations.
- Cross-Distribution Restores - Enables the reinstallation of a previous system state and bootloader even after a different OS has been installed.
