Selfhosted
A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.
Rules:
-
Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.
-
No spam posting.
-
Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.
-
Don't duplicate the full text of your blog or github here. Just post the link for folks to click.
-
Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).
-
No trolling.
-
No low-effort posts. This is subjective and will largely be determined by the community member reports.

The main advantages of Kopia, are speed and destination flexibility.
The off-site storage does not need to have Kopia installed. It can be a mounted network location, an FTP server. Whatever. A generic cloud storage bucket like Backblaze B2.
That's why just a router with and external drive hooked up is able to suffice.
For all of these, you can connect multiple Kopia instances to that same destination, and each client can browse backups, restore from them, and backup their own files to the destination. It even performs file deduplication across different source device. All while that destination device or service, has no access to your encrypted files.
With borg, you need something like a Pi that can have borg installed. (You can also do this with Kopia, in which case the Kopia instance on the destination device is also able to manage the backups).
Kopia also beats borg and restic in speed. My daily backups typically complete within a minute or two. I used to use Duplicati, with which it was common for it to take up to an hour. When it started regularly taking more than an hour, I switched to Kopia.
Kopia is not the fastest for initial backup. The speed of this varies depending on destination type. It does not compress by default, but you can enable almost any type of compression you want. No, what it is fastest at is updating backups. If there is nothing to update, it does not take forever for it to figure that out. Kopia does it in seconds.
thanks! I installed it and created my first backup. I'll test it and see how it goes. It looks good. Thank you!
I can't find anything related to systemd or cron. Does it have its own scheduler? I already set policies. I'm just wondering if I forgot something to setup.
Depends. If you are running it as a service that starts with the system (
sudo sysemctl enable kopiashould work with most install methods, as kopia comes with a systemd service you only need to enable) then yes, it will use its own scheduler.If you want to use your own scheduling, you'd use anything that can execute a command on a schedule.
Thank you!
I couldn't find a systemd unit or service.
I'm not yet sure about that
How did you install kopia? What system are you on?
It needs to be running, if it is, it will follow the policy. Systemd can start it with the system, but you can also start it some other way. Or you can execute snapshots without it constantly running, via cron/script. It's up to you.
