all good. thanks for exchanging our experience :)

kopia wasn’t running durin the week. I didn’t look into the server configuration since it introduces user handling and that seemed to be overkill for the task but running as daemon would lead to a funcitoning system of course.

this is my kopia.service file in case some else finds it and is interested in it

[Unit]

Description=kopia backup

[Service]

User=root ExecStart=$HOME/bin/backup_kopia

[Install]

WantedBy=multi-user.target

where $HOME/bin/backup_kopia contains

#!/bin/bash

/usr/bin/kopia repository connect filesystem --path $KOPIA_REPO --password $KOPIA_PASSWORD

/usr/bin/kopia snapshot create $HOME/folder_to_backup

and my kopia.timer

[Unit]

Description=Run kopia backup

[Timer]

OnCalendar=hourly

Persistent=true

[Install]

WantedBy=timers.target

It’s a fedora server.

according to kopia’s repo, there is no official systemd service https://github.com/kopia/kopia/issues/2685 and there is none on my system.

in the past week, it did not backup anything. Hence, there is no scheduler built into kopia automagically as described/ hinted in the docs.

I just wrote a systemd service and timer and I’ll see if it works. I’m not the best in using systemd. I dislike it, I like cron for it’s simplicity.

Even if it works then, I wouldn’t recommend it to anyone because info about the scheduler is rare and the docs do not even cover the topic.

I couldn’t find a systemd unit or service.

Kopia will then automatically begin taking the snapshot following the settings you set for the policy. link

I’m not yet sure about that

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.

is that your only expansion option on the system you have?

For now, yes, that’s the only option. I’ll look into internal drives the next time.

thanks for the info about RAID 1 and BTRFS in raid1c2

I’ll look into kopia as well since I only knew about borg.

I am using mergerfs for years, it’s really neat.

thanks for sharing all of that!
