Welcome to Bacsy's documentation!

What is Bacsy?
Bacsy is a backup system (hence the name).
- A device using Bacsy to backup its data will send the backups to other devices also running Bacsy.
- Easy to add a new device
- In a default configuration, if you add a new device running Bacsy to your LAN, backups will automatically be stored on that device.
- Backups will usually be stored on multiple devices.
- Fast to setup ...
- A basic configuration should be quick to achieve
- ... yet extremely adjustable
- A plethora of configuration options are available.
How does Bacsy work?
- Bacsy is made up out of two components:
- A Client
- The client generates backups and sends them to one or more servers.
- A Server
- A server accepts and stores backups for one or more clients.
Most systems will have both a client and a server running. Systems that have no need to generate backups of their own (e.g. dedicated backup servers) will have only a server running.
A client has a number of sources. Each source specifies what files should be backed up, how often they should be backed up, how important they are, etc.
When the client has a backup it needs stored, it will ask qualifying servers if they can store this backup. If the servers respond they can, the backup will be sent to them.
A Bacsy server stores backups. Each server has one or more stores. A store is a location where backups can be stored, usually some directory on some drive. Backups will often be stored to multiple stores on the same server, for redundancy purposes.
