rsync-time-backup VS sanoid

Hi Hacker News,

I'm excited to share my recent project, where I took on the challenge of porting a popular but untested 600+ line Bash script to Python. The outcome is [`rsync-time-machine.py`](https://github.com/basnijholt/rsync-time-machine.py), a Python implementation of the [`rsync-time-backup`](https://github.com/laurent22/rsync-time-backup) script. It provides Time Machine-style backups using rsync and creates incremental backups of files and directories to the destination of your choice.

The tool is designed to work on Linux, macOS, and Windows (via WSL or Cygwin). Its advantage over Time Machine is its flexibility - it can backup from/to any filesystem and works on any platform. You can also backup to a Truecrypt drive without any issues.

Unlike the original Bash script, `rsync-time-machine.py` is fully tested. It has no external dependencies (only requires Python ≥3.7), and it is fully compatible with [`rsync-time-backup`](https://github.com/laurent22/rsync-time-backup). It offers pretty terminal output and is fully typed.

Key features include:

* Each backup is in its own folder named after the current timestamp.

Here's a script that someone made that simplifies the setup. I haven't used this script, but it looks pretty good: https://github.com/laurent22/rsync-time-backup

I do most of my backups using some version of this script to (efficiently) keep a long backup history: https://github.com/laurent22/rsync-time-backup

Here is a scripted version. Honestly, I’d rather roll my own but it’s still helpful: https://github.com/laurent22/rsync-time-backup

I’m on the other end of the spectrum. I like knowing the flags and settings I use to create the pools.

For snapshots and replication take a look at sanoid (https://github.com/jimsalterjrs/sanoid).

I use a combo of PBS and ZFS with Sanoid. The ZFS snapshots are nice because you define it all in a config file with frequent, hourly, daily, weekly, monthly snaps retained however you want. Importantly I use that on the root pool as well as my data pools. With PBS I have a custom retention config and have it backing up VMs and LXCs every couple hours. The PBS dedupe functionality makes it possible to keep full backups going back ages with minimal storage consumption, just the changed blocks. PBS is running inside a VM yes, but it’s storage is on another pool.

No, it's written by the developer of Sanoid and Syncoid. The foremost open source ZFS snapshotting tool. He contributes on this sub all the time.

Hi there! Not so much to answer your questions, but are you aware of Sanoid and syncoid? It does backup and remote Sync in the most seamless way. Perhaps this would solve some of your concerns...
