Install freydis locally

$ gem install --user-install freydis

Usage

$ freydis -h

Examples

0x01 - Initialisation

First, you need a config file and a disk encrypted.

$ freydis --disk sdc --encrypt --save

The config file will be created at ~/.config/freydis/freydis.yaml.

---
:disk: /dev/disk/by-id/usb-SABRENT_SABRENT_DB9876543214E-0:0
:paths: []

• disk: save the full path by-id for sdc here.
• paths -> An Array which contain a list of absolute paths for backup.

0x02 - First backup

Freydis will use rsync, all paths must be separated by a comma:

$ freydis --backup --paths-add /home,/etc --save

0x03 - Restore

With --disk and --paths-add saved in the config file, you only need to write:

$ freydis --restore

Freydis will restore all files in /.

0x04 - Secrets

Freydis can store secrets (GPG Key and pass directory for now) and restore them if need:

$ freydis --gpg-recipient szorfein@protonmail.com --secrets-backup
$ freydis --gpg-recipient szorfein@protonmail.com --secrets-restore

The option --secrets-restore use gpg --import if the key is no found on your system.

Tips

If you lost the config file, freydis has made a copy on your device when you're done your first --backup:

$ freydis --open --disk sdc
$ cp -a /mnt/freydis/home/user/.config/freydis ~/.config/

And you can use freydis normally.
