Kontact wouldn't store a copy there.
However, older versions had that as the default locations, so it could have 
been the correct location for you depending on for how many years you have 
been using Kontact.

Right, in your case, remote calendars, there wouldn't be anything in there.

Ok. This would have been the default location for newer versions. Seems you 
have been using neither, possibly a manually configured address book?

Ah, excellent!

It should also be in such config files, however the name of the address book 
might not have been stored that way which is why grepping for it wouldnt 
necessarily find it.

Do you have a list of those akonadi_*_resource_*rc files?

Another thing you could try is to restore the full setup.
Fot this you would need to stop the Akonadi data exchance service with

akonadictl stop

Then overwrite its current files with the one from the backup, i.e.
files from ~/home-backup/.local/share/akonadi to .local/share/akonadi
from ~/home-backup/.config/akonadi to .config/akonadi
the akonadi_* config files to .kde/share/config

and then restart the service
akonadictl start

Cheers,
Kevin
