The right way to again up Linux directories over a community with restic
Jack Wallen walks you thru the method of putting in and utilizing the restic backup instrument over a community, for simple information backup and restore.
There are such a lot of choices when you have to again up your information. That is very true when utilizing the Linux platform. You may go together with a full-blown GUI software or a easy command line instrument (or something in between). One such command line instrument (that has quite a lot of potential) is restic . Restic is a quick, safe back-up software that may deal with native or community again ups with pace and ease. With this instrument, you possibly can create bash scripts or cron jobs to fit your Linux backup wants.
I wish to stroll you thru the set up of restic, the creation of a distant repository, and backing up information over your community. I will display on the Ubuntu Server 18.04 platform.

What you want
To efficiently make this work, you want the next:
A Ubuntu Server 18.04 occasion. One other Linux server (or desktop) that homes the information to be backed up. SSH key authentication configured between the 2 machines (See: The right way to arrange ssh key authentication). A person with sudo privileges.
With these bits in hand, let’s get to work.
Putting in restic
As a result of restic might be present in the usual Ubuntu repositories, set up might be taken care of with a single command:
sudo apt-get set up restic -y
As soon as the set up completes, you are able to proceed.
Making a repository
The following step is to create a repository. First, we’d like a vacation spot listing on our distant server. Log into that server and create the brand new listing with the command:
sudo mkdir /srv/restic-repo
Make sure that to change the permissions for that listing as wanted. Say, for instance, the person jack will deal with the backups. For that, you wish to change the possession with the command:
sudo chown jack.jack /srv/restic-repo
You is perhaps higher off creating a bunch that may use the backups, add all the required customers to that group, and alter the group possession of the listing with the command:
sudo chgrp -R /srv/restic-repo GROUP
The place GROUP is the identify of the group you created.
Subsequent we have to initialize the repository. From the consumer machine, difficulty the command:
restic -r sftp:USER@SERVER_IP:/srv/restic-repo init
The place USER is the distant username and SERVER_IP is the IP deal with of the distant server. You’ll be prompted for the SSH key password, after which prompted to create (and confirm) a password for the repository. As soon as that command completes, you are able to again up.
For example now we have the listing ~/information on the consumer machine, and we wish to again it as much as the distant repository we simply created. The command to do that is:
restic backup information -r sftp:USER@SERVER_IP:/srv/restic-repo
The place USER is the distant person and SERVER_IP is the IP deal with of the distant server.
Restic will ship the backup to the distant server and report again the outcomes (Determine A).
Determine A: The outcomes of our distant backup.
Restoring from a backup
Now that you just backed as much as the distant repository, how do you restore that information again to your native machine? Straightforward. On the native consumer, difficulty the command:
restic restore newest –target ~/data-restore -r sftp:USER@SERVER_IP:/srv/restic-repo
The place USER is the distant person and SERVER_IP is the distant server IP deal with.
The above command will restore the information from the distant repository in a newly created ~/data-restore listing (restic will create this for you).
Congratulations, you backed up and restored your information listing to a distant restic repository. It is best to now have all the knowledge you have to use restic in helpful and artistic methods.
