Tool to make remote-incremental backups which consist of a mirror and historical snapshots of the target data.
These snapshots are created using hard links and can be taken as often as needed as they are cheap both in time and
space. rincr can manage these snapshots, clean up unnecessary data and also restore files to earlier versions.
Note: This project was previously called kbackup. See this issue for more information.
Create incremental backups with a simple command:
# Backup local folder to remote server
rincr ~/mydata user@server:~/backups
# Backup remote folder to local directory
rincr user@server:~/mydata ~/backups
# Backup multiple sources
rincr ~/docs ~/photos user@server:~/backups
rincr creates space-efficient snapshots using hard links. Each backup is a complete copy that you can browse and restore from directly. Historical snapshots are stored in .rincr/ subdirectories at the destination.
Download the right binary for your OS and Architecture (all binaries available on Github):
Make sure it is executable and then place it anywhere in your $PATH:
chmod +x rincr
mv rincr ~/bin/rincr # Use whatever location you put your user binaries in.
Test that it works:
rincr --version
Note: This software is not yet stable; there may be backwards-incompatible changes before v1. Use at your own risk.
Create backups with automatic pruning to manage disk space:
# Backup with default retention (24h, 30d, 12m, 10y)
rincr --prune ~/mydata myserver:~/backups
# Custom retention rules
rincr --prune --hourly=12 --daily=15 --monthly=6 --yearly=5 ~/mydata myserver:~/backups
Prune existing backups without syncing new data:
rincr prune myserver:~/backups/mydata
Note: When pruning, provide the full path including the target directory name.
Restore files from any backup snapshot:
# Restore from latest backup
rincr restore --latest myserver:~/backups/mydata path/to/file ~/restored/
# Restore from specific time point
rincr restore --from=12h myserver:~/backups/mydata path/to/file ~/restored/
# Restore multiple files
rincr restore --latest myserver:~/backups/mydata file1 file2 dir/ ~/restored/
Files are searched from newest to oldest backups. Only changed files are transferred using rsync.
# Initial state - source has files
$ ls -A ~/mydata
