# Sync Algorithm V3
|
||
|
|
|
||
|
|
Drafted on 20240117.
|
||
|
|
|
||
|
|
An absolutely better sync algorithm. Better for tracking deletions and better for subbranching.
|
||
|
|
|
||
|
|
## Huge Thanks

Basically a combination of algorithm v2 + [synclone](https://github.com/Jwink3101/syncrclone) + [rsinc](https://github.com/ConorWilliams/rsinc) + (some of rclone [bisync](https://rclone.org/bisync/)). All of the later three are released under MIT License so no worries about the licenses.

|
## Features
|
||
|
|
|
||
|
|
Must have
|
||
|
|
|
||
|
|
1. true deletion detection
|
||
|
|
2. deletion protection (blocking) with a setting
|
||
|
|
3. transaction from the old algorithm
|
||
|
|
4. user warning show up, **new algorithm needs all clients to be updated!** (deliberately corrput the metadata file??)
|
||
|
|
5. filters
|
||
|
|
6. conflict warning
|
||
|
|
7. partial sync
|
||
|
|
|
||
|
|
Nice to have
|
||
|
|
|
||
|
|
1. true time and hash
|
||
|
|
2. conflict rename
|
||
|
|
|
||
|
|
## Description
|
||
|
|
|
||
|
|
We have _five_ input sources: local all files, remote all files, _local previous succeeded sync history_, local deletions, remote deletions.
|
||
|
|
|
||
|
|
Init run, consuming local deletions and remote deletions :
|
||
|
|
|
||
|
|
TBD
|
||
|
|
|
||
|
|
Later runs, use the first, second, third sources **only**.
|
||
|
|
|
||
|
|
TBD
