Rsnapshot: Open-Source Utility for Incremental Linux Backup
An open-source utility for Linux that provides incremental backup functionality using rsync, making it easy to maintain a local backup of a remote system by only transferring the changes since the last backup.
What is Rsnapshot?
Rsnapshot is an open-source backup utility for Linux operating systems that provides incremental backup functionality using rsync. It is designed to make it easy to maintain a backup of a remote system by only transferring the changes that have occurred since the last backup.
Some key features of Rsnapshot include:
- Incremental backups using rsync - only changed files are transferred after the initial backup, making the process very efficient.
- The ability to keep multiple backups - daily, weekly, and monthly backups can be maintained.
- Hardlink based - uses hardlinks whenever possible to save space.
- Rotation of backups - old backups are automatically removed based on configurable settings.
- Backup to local, remove, or mounted filesystems.
- Configuration using a single config file.
Rsnapshot is a popular choice for Linux admins to backup remote servers, databases, client machines, and other systems. The incremental nature allows backing up frequently without using a lot of bandwidth or disk space after the initial seed backup. Retaining multiple increments (daily, weekly, etc.) provides redundancy and facilitates restore from different points in time.
