**An attempt to describe / outline the backup regime - where Syncthing is part of it:**

* JD_B\ (*technical reason - since this is backup* *target* *, it is split into separate "Shared folder" in Synology NAS - b for backup*)

## BACKUP - intent / design / what should it cover:

  - Trying to protect against / reason for backup / the most likely bad things to happen:

- USBCopy (Synology) \*described further down - (automagically copy files to external USB drive when connected or powered on)  
\* rsync (Synology) \*described further down

- **Scenario 3** :

- **Cloud Sync** (Synology NAS)

- **USB Copy** (Synology NAS) \> can set trigger conditions and tasks - example; run task if external drive is connected or powered on

- **rsync**
  - I use built in rsync clients on Synology NAS servers, Hyper Backup with latest, older clients with the older
  - 

**NAS servers**  
\* [DS124](https://www.synology.com/en-global/products/DS124) \< main server, always on/powered - runs Syncthing  
\* [DS209](https://global.download.synology.com/download/Document/Hardware/DataSheet/DiskStation/9-year/DS209/enu/Synology_DS209_Data_Sheet_enu.pdf) \< for rsync backups, runs RAID1 w 2 drives, always on, powered  
\* DS107+ \< for less frequent rsync backups, poweroff most of the time, wakes on schedule
