rclone serve restic

Serve the remote for restic's REST API.

Synopsis

Run a basic web server to serve a remote over restic's REST backend
API over HTTP. This allows restic to use rclone as a data storage
mechanism for cloud providers that restic does not support directly.

Restic is a command-line program for doing
backups.

The server will log errors. Use -v to see access logs.

--bwlimit will be respected for file transfers.
Use --stats to control the stats printing.

Setting up rclone for use by restic

First set up a remote for your chosen cloud provider.

Once you have set up the remote, check it is working with, for example
"rclone lsd remote:". You may have called the remote something other
than "remote:" - just substitute whatever you called it in the
following instructions.

Now start the rclone restic server

rclone serve restic -v remote:backup

Where you can replace "backup" in the above by whatever path in the
remote you wish to use.

By default this will serve on "localhost:8080" you can change this
with use of the --addr flag.

You might wish to start this server on boot.

Adding --cache-objects=false will cause rclone to stop caching objects
returned from the List call. Caching is normally desirable as it speeds
up downloading objects, saves transactions and uses very little memory.

Setting up restic to use rclone

Now you can follow the restic
instructions
on setting up restic.

Note that you will need restic 0.8.2 or later to interoperate with
rclone.

For the example above you will want to use "http://localhost:8080/" as
the URL for the REST server.

For example:

$ export RESTIC_REPOSITORY=rest:http://localhost:8080/
$ export RESTIC_PASSWORD=yourpassword
$ restic init
created restic backend 8b1a4b56ae at rest:http://localhost:8080/

Please note that knowledge of your password is required to access
the repository. Losing your password means that your data is
irrecoverably lost.
$ restic backup /path/to/files/to/backup
scan [/path/to/files/to/backup]
scanned 189 directories, 312 files in 0:00
[0:00] 100.00%  38.128 MiB / 38.128 MiB  501 / 501 items  0 errors  ETA 0:00
duration: 0:00
snapshot 45c8fdd8 saved

Multiple repositories

Note that you can use the endpoint to host multiple repositories. Do
this by adding a directory name or path after the URL. Note that
these must end with /. Eg

$ export RESTIC_REPOSITORY=rest:http://localhost:8080/user1repo/
# backup user1 stuff
$ export RESTIC_REPOSITORY=rest:http://localhost:8080/user2repo/
# backup user2 stuff

Private repositories

The--private-repos flag can be used to limit users to repositories starting
with a path of /<username>/.

Server options

Use --addr to specify which IP address and port the server should
listen on, eg --addr 1.2.3.4:8000 or --addr :8080 to listen to all
IPs. By default it only listens on localhost. You can use port
:0 to let the OS choose an available port.

If you set --addr to listen on a public or LAN accessible IP address
then using Authentication is advised - see the next section for info.

You can use a unix socket by setting the url to unix:///path/to/socket
or just by using an absolute path name. Note that unix sockets bypass the
authentication - this is expected to be done with file system permissions.

--addr may be repeated to listen on multiple IPs/ports/sockets.

--server-read-timeout and --server-write-timeout can be used to
control the timeouts on the server. Note that this is the total time
for a transfer.

--max-header-bytes controls the maximum number of bytes the server will
accept in the HTTP header.

--baseurl controls the URL prefix that rclone serves from. By default
rclone will serve from the root. If you used --baseurl "/rclone" then
rclone would serve from a URL starting with "/rclone/". This is
useful if you wish to proxy rclone serve. Rclone automatically
inserts leading and trailing "/" on --baseurl, so --baseurl "rclone",
--baseurl "/rclone" and --baseurl "/rclone/" are all treated
identically.

TLS (SSL)

By default this will serve over http. If you want you can serve over
https. You will need to supply the --cert and --key flags.
If you wish to do client side certificate validation then you will need to
supply --client-ca also.

--cert should be a either a PEM encoded certificate or a concatenation
of that with the CA certificate. --key should be the PEM encoded
private key and --client-ca should be the PEM encoded client
certificate authority certificate.

--min-tls-version is minimum TLS version that is acceptable. Valid
values are "tls1.0", "tls1.1", "tls1.2" and "tls1.3" (default
"tls1.0").

Authentication

By default this will serve files without needing a login.

You can either use an htpasswd file which can take lots of users, or
set a single username and password with the --user and --pass flags.

If no static users are configured by either of the above methods, and client
certificates are required by the --client-ca flag passed to the server, the
client certificate common name will be considered as the username.

Use --htpasswd /path/to/htpasswd to provide an htpasswd file. This is
in standard apache format and supports MD5, SHA1 and BCrypt for basic
authentication. Bcrypt is recommended.

To create an htpasswd file:

touch htpasswd
htpasswd -B htpasswd user
htpasswd -B htpasswd anotherUser

The password file can be updated while rclone is running.

Use --realm to set the authentication realm.

Use --salt to change the password hashing salt from the default.
