24.2 Disk Backup

20220704

A good practise might be to use an encrypted cloud store like MEGA to backup important data. MEGA provides a free account with 20GB of storage and a 6 hour download limit of 5GB if their servers get busy. Increase that to 400GB of storage and 1TB transfer per month for EUR5 per month.

Install the megasync app by adding the Mega repository as the file /etc/apt/sources.list.d/megasync.list:

deb [signed-by=/usr/share/keyrings/meganz-archive-keyring.gpg] https://mega.nz/linux/repo/xUbuntu_22.04/ ./

Download the key:

wget --inet4-only -O- https://mega.nz/linux/repo/xUbuntu_22.04/Release.key | gpg --dearmor | sudo tee /usr/share/keyrings/megasync-archive-keyring.gpg

You can then start megasync.

MEGA note that all data stored on their servers is encrypted, and not even they can access your data on their servers. The public megasync client is open source and hosted on github https://github.com/meganz/MEGAsync/. It is assumed this is the version that is installed from the MEGA repository.

For the free account MEGA has a download limiter which during busy times limits downloads to 5GB per 6 hours. This is IP address based so if your server changes IP address or your are using a VPN with changing IP addresses then you can exceed the limit. During light usage of the MEGA servers you may also get higher limits.
