A few string comments
#: data/app.metainfo.xml.in:24
"Create backups locally and remote"
Perhaps this should be "remotely".
#: src/borg/error.rs:126
"Aborted because too long not connected to power."
I'm not sure what this means.
#: src/ui/dialog_setup.ui:324
"Locations with explicit borg-backup support can provide better Performance.[...]"
What's the capital 'P' for here?
