Restic with Backblaze B2 is a great combination to keep multiple machines with similar data (vms, containers, source code…) backed up securely and for cheap. Here's my setup…
I have been using restic for the past two weeks. Restic is the backup tool I wished for, but had not realized it already existed!
Here's how I'm using it:
MacOS El Capitan,
Install ( read-the-docs ):
$ brew install restic # MacOS
$ pkg install restic # FreeBSD
Sign-up for or provision remote storage ( options supported by restic ):
I am using Backblaze B2 since it allows backing up multiple machines to the same repo, while restic does the deduplicating and encryption before uploading part.
B2 is inexpensive and fast and I found it very simple to set up. Let's say you could get restic+B2 up and running possibly in less time than it takes to only read through the instructions to perform the same actions on AWS.
Configure the remote storage repo ( docs ):
$ nano ~/.restic export B2_ACCOUNT_ID="<account-id>" export B2_ACCOUNT_KEY="<account-key>" export RESTIC_PASSWORD="<encryption-password>" export RESTIC_REPOSITORY="<remote-repo>" $ chmod 600 ~/.restic
If you intend to back up source code directories, excluding cache folders might appeal to you. Let us make a shell script to automate remembering that.
If you don't have a private binaries folder, create one:
$ mkdir -p ~/.bin/
Create a bash script with the content:
$ nano ~/.bin/backup.sh #!/usr/bin/env bash source ~/.restic restic backup `pwd` \ --exclude=__pycache__ \ --exclude=.git
Make it executable:
$ chmod +x backup.sh
Add the private bin folder to
$PATH environment variable, assuming bash.
$ echo 'export PATH="~/.bin:$PATH"' >> ~/.bash_profile
Now you can execute
$ backup.sh in any directory to back it up securely.
cough protip cough. I am not entirely sure if this is a good idea, but so far so good!
$ ln -s ~/.bin/backup.sh ~/.bin/,, $ cd directory-to-backup $ ,,<ENTER>
Restoring specific files is quite straightforward too:
Imagine you want to restore a file named
$ restic find fabfile.py Found matching entries in snapshot [SNAPSHOT-ID] /example/project/fabfile.py $ restic restore [SNAPSHOT-ID] --target /tmp/phew --include /example/project/fabfile.py
It will be saved as
That's all there is for basic usage!
