  • How do I exclude uncritical data from my backup?

    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.

  • How much storage space do I need to backup my files?

    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. 

  • Which operating systems are supported?

    • Windows
    • Mac OS X
    • Linux
    • BSDs
  • How do I create an ed25519 SSH public/private key pair?

    To create ed25519 SSH public/private key pair, you need OpenSSH 6.5 or newer.

    ssh-keygen -t ed25519 -C "name.surname@example.com"

    Die Ausgabe von ssh-keygen sieht in etwa wie folgt aus:

    Generating public/private ed25519 key pair.
    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.
    The key fingerprint is:
    SHA256:DpS2gFLsSAfCuoBjgf7UEsQY3lKrDbEpnOn+rIlg+6k name.surname@example.com
    The key's randomart image is:

  • How many backups (iterations) do I have?

  • What is the difference between GB (Gigabyte) and GiB (Gibibyte)?

    The first one mentioned uses decimal (SI) and the second one binary (IEC) unit prefixes. The actual sizes are shown in the table beneath.

  • Is all of my data transfered each time?

    No, only the data changed will be transmitted: edited existing documents and well as new documents and settings.

  • How long does a backup process take?

    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).

  • How frequently should I run the backup process?

    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.

  • How are my backups structured?

    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:

    daily.0

    last night

    daily.1

    the night before last

    daily.2

    the night 3 days ago

    daily.3

    the night 4 days ago

    daily.4

    the night 5 days ago

    daily.5

    the night 6 days ago

    daily.6

    last week (7 days ago)

    weekly.0

    the night 2 weeks ago

    weekly.1

    the night 3 weeks ago

    weekly.2

    the night 4 weeks ago

    weekly.3

    the night 5 weeks ago

    monthly.0

    the night 2 months ago

    monthly.1

    the night 3 months ago

    monthly.2

    the night 4 months ago
