Virtualmin backups have many features, and here are the current destination options:
- Local folder
- FTP
- SSH
- Webmin
- Amazon S3
- Rackpace
- Download link
We will add native support for Syncthing in Virtualmin, which will permit things that none of the current options can do.
| Criteria | local folder | FTP | SSH | Webmin | Amazon S3 | Rackpace | Download link | Syncthing (partially developed already) |
| Full data control (does not require external service) | yes | yes | yes | yes | no | no | yes | yes |
| Automatic / Unattended | yes | yes | yes | yes | yes | yes | no | yes |
| Off-server | no | yes | yes | yes | yes | yes | yes | yes |
| Devices can be behind the firewall, and without a fixed IP address | n/a | no | no | no | n/a | n/a | yes, manually | yes, to your laptop or an Android |
| P2P / multiple (each node can sync with the others, which is different than setting up multiple destinations) | no | no | no | no | depends on provider | depends on provider | no | yes |
| Only send new or modified files | n/a | no | no (unless rsync) | ? | ? | ? | n/a | yes |
| Cold storage / asynchronous (machine can be turned on/off anytime, and it just gets data when machine is online) | n/a | no | no | ? | n/a | n/a | n/a | yes |
| Data is encrypted in transport | n/ a | If FTPS | yes | yes? | yes? | yes? | yes, with Virtualmin HTTPS | yes |
| Throttling: Can set Incoming and Outgoing Rate Limit (KiB/s) | n/ a | ? | ? | ? | ? | ? | no | yes |
To be added to the chart
- Syncthing (if configured that way) can also receive data. So it can be a way to send back a backup or other data.
- Protection against crypto-locker attack, as explained here
- Syncthing can sync data with an untrusted node by encrypting the data. So one of the nodes can be a rented server with a lof of disk space.
Status as of 2023-03-07
- Within the WikiSuite installer, a Syncthing installer is provided.
- Once Syncthing is installed for a Virtual Server, you need to set up automated backups to a directory and use that directory for Syncthing
This all works but we want to make it easier
- Spin out a Syncthing for Virtualmin app that is totally independant from WikiSuite. So you can install on any Virtualmin instance
- When the app is installed, add Syncthing as an option directly along SSH, FTP, Amazon S3, etc.
