Synology

How-To

Add a CloudStation ShareSync folder

On the server:

• Go to Main Menu (top left), select Drive Admin Console, go to Team Folder, then select the folder to enable.

On the Client:

• Go to the CloudStation Sync client, and configure the new share.

Install borgbackup server

Reference:

• https://roll.urown.net/NAS/borg-backup-server.html

• Add https://packages.synocommunity.com/ as Package Source.
• Install Borg from the community package list.
• Create a new user borg, and add it to group administrator (to enable ssh access).

sudo su -
cd ~borg
mkdir -p .ssh
touch .ssh/authorized_keys
chown -R borg:users .ssh
chmod 0700 .ssh
chmod 0600 .ssh/*

• Create a password-less ssh key for that user

ssh-keygen -t ed25519 -f id_ed25519_borgbackup

• Login into synology as admin, then create the restricted .ssh/authorized_keys

command="/usr/local/bin/borg serve --restrict-to-path /volume1/BorgBackup/" ssh-ed25519 AAAAC3...
