To create ed25519 SSH public/private key pair, you need OpenSSH 6.5 or newer.
ssh-keygen -t ed25519 -C "firstname.lastname@example.org"
Die Ausgabe von ssh-keygen sieht in etwa wie folgt aus:

Enter file in which to save the key (/home/steppingstone/.ssh/id_ed25519):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/steppingstone/.ssh/id_ed25519.
Your public key has been saved in /home/steppingstone/.ssh/id_ed25519.pub.

In order to use less storage for your backup, you can exclude uncritical data from your backup.
Open your stoney backup client and click "backup". Deselect the folders which you want to exclude from your backup and click "save" to confirm these settings.
You have access at any time to 7 daily, 4 weekly and 3 monthly backups. So documents and other data which are older than a month and were changed since then are available in three versions. Therefore you need approximately three times as much storage as your data on your hard disk currently uses.
For a backup size over X Gibibyte, your can calculate with factor 2.1. For example 30 Gibibyte Data need 63 Gibibyte backup space.
Of course not! Moreover, your data is encrypted while being transmitted over the Internet.
You have constant access to 7 daily, 4 weekly and 3 monthly backups.
No, only the data changed will be transmitted: edited existing documents and well as new documents and settings.
This depends on the amount of data you have, the number of changes from the previous day, and your upload bandwidth (dependent on your internet access).
Since your backups are made once per day, you should automatically trigger the process at least once within each 24 hours. If required, for example when you are away from the office with a notebook and have made many changes to your data, then several manual backups on the same day are recommended.
stoney backup offers you access to 7 day, 4 week and 3 month backups. You write your data into the "incoming" list while the backups are in the "snapshots" list and are subdivided as follows:
the night before last
the night 3 days ago
the night 4 days ago
the night 5 days ago
the night 6 days ago
last week (7 days ago)
the night 2 weeks ago
the night 3 weeks ago
the night 4 weeks ago
the night 5 weeks ago
the night 2 months ago
the night 3 months ago
the night 4 months ago
Yes, you only have read access to your backup files. So neither you, nor somebody else can inadvertently change or delete the data.
