Packerd

Packerd is a simple service that generates on-demand backup bundles and serves them remotely to authorized clients.

Get started

Compile the project with:

go build -o build/packerd

Config

Parameters can be passed via command line of be defined in a config file

Command line

$ ./packerd -h
Packerd is a backup utility for authenticated remote clients

Usage:
  packerd [flags]

Flags:
      --cert string     the certificate file (TLS only)
      --config string   the config file to use
  -h, --help            help for packerd
      --key string      the TLS encryption key file
  -p, --port int        port to bind to (default 80)
      --tls             whether to use TLS encryption (cert and key required)

The config file is mandatory. However, CLI parameters can override the port, cert, key and tls for easier testing.

Config file

Copy config.template.yaml and adapt it to work for the data you want to back up.

port: 8443
tls: true
cert: /path/to/cert.pem   # not needed it tls = false
key: /path/to/key.pem     # not needed it tls = false
paths:
- id: media
  token: "1234567890123456789012345678901234567890"
  path: /var/lib/media
- id: other
  token: "0123456789012345678901234567890123456789"
  path: /var/lib/other

By default, config.yaml is attempted on the current directory. Otherwise:

$ packerd --config my-config.yaml

Fetching the back up remotely

From a remote location, make a GET request like so:

$ NAME = "media"
$ TOKEN = "1234567890123456789012345678901234567890"
$ curl https://my-server.net:8443/backup/$NAME/$TOKEN > $NAME.tar.gz

Using a self signed certificate

$ openssl req -x509 -newkey rsa:4096 -keyout key.pem -out cert.pem -days 10000 -nodes

Then, run packerd:

$ packerd --tls --cert cert.pem --key key.pem -p 8443

And finally, tell curl to accept the self-signed certificate.

$ NAME = "media"
$ TOKEN = "1234567890123456789012345678901234567890"
$ curl --insecure https://localhost:8443/backup/$NAME/$TOKEN > $NAME.tar.gz
