The required version of restic backup client to use with `rest-server` is [v0.7.1](https://github.com/restic/restic/releases/tag/v0.7.1) or higher.
## Installation
## Build
### From source
For building the `rest-server` binary run `CGO_ENABLED=0 go build -o rest-server ./cmd/rest-server`
#### Build
## Docker
```make```
### Build image
or
Put the `rest-server` binary in the current directory, then run:
```go run build.go```
docker build -t restic/rest-server:latest .
If all goes well, you'll find the binary in the current directory.
Alternatively, you can compile and install it in your $GOBIN with a standard `go install ./cmd/rest-server`. But, beware, you won't have version info built into binary when compiled that way!
### Pull image
#### Install
```make install```
Installs the binary as `/usr/local/bin/rest-server`.
Alternatively, you can install it manually anywhere you want. It's a single binary, there are no dependencies.
### Docker
#### Build image
```make docker_build```
#### Pull image
```docker pull restic/rest-server```
docker pull restic/rest-server
## Usage
To learn how to use restic backup client with REST backend, please consult [restic manual](http://restic.readthedocs.io/en/latest/030_preparing_a_new_repo.html#rest-server).

By default the server persists backup data in `/tmp/restic`. To start the server with a custom persistence directory and with authentication disabled:
```
rest-server --path /user/home/backup --no-auth
```
rest-server --path /user/home/backup --no-auth
To authenticate users (for access to the rest-server), the server supports using a `.htpasswd` file to specify users. You can create such a file at the root of the persistence directory by executing the following command (note that you need the `htpasswd` program from Apache's http-tools). In order to append new user to the file, just omit the `-c` argument. Only bcrypt and SHA encryption methods are supported, so use -B (very secure) or -s (insecure by today's standards) when adding/changing passwords.
```
htpasswd -B -c .htpasswd username
```
htpasswd -B -c .htpasswd username
If you want to disable authentication, you must add the `--no-auth` flag. If this flag is not specified and the `.htpasswd` cannot be opened, rest-server will refuse to start.
NOTE: In older versions of rest-server (up to 0.9.7), this flag does not exist and the server disables authentication if `.htpasswd` is missing or cannot be opened.
By default the server uses HTTP protocol. This is not very secure since with Basic Authentication, username and passwords will travel in cleartext in every request. In order to enable TLS support just add the `--tls` argument and add a private and public key at the root of your persistence directory. You may also specify private and public keys by `--tls-cert` and `--tls-key`.

You may also specify private and public keys by `--tls-cert` and `--tls-key`.
Signed certificate is required by the restic backend, but if you just want to test the feature you can generate unsigned keys with the following commands:
```
openssl genrsa -out private_key 2048
openssl req -new -x509 -key private_key -out public_key -days 365
```
openssl genrsa -out private_key 2048
openssl req -new -x509 -key private_key -out public_key -days 365
The `--append-only` mode allows creation of new backups but prevents deletion and modification of existing backups. This can be useful when backing up systems that have a potential of being hacked.
