Hi,
I want to switch from Kubuntu 11.10 to 12.04.
In earlier time backup of my mails was easy:
tar the .kde folder and you're done.
Now we have akonadi (and nepomuk)& a mysql server running
in my opinion:
1. overkill: a simple file based sqlite would have beet simpler
2. security issue due to indexing:
Immagine I have a *temporarily* mail with some
"private" stuff like credit card number / password.
If I delete (or wipe) my email: how can I get sure
that this data is *not* surviving as ghost in some index file.
The same issue nepomuk: I do not want a system using constantly
cpu/memory/disk indexing stuff which I want to search only
from time to time.
I would prefer to search explicitly when I need to, but nepomuk/akonady
(or only akonady do not remember) need to run or Kontakt& friends do
not work anymore.
May I add a 3rd:
3. It makes backing up of emails, contacts etc a nightmare.
Ok, after my remarky (yes I am whining a little bit) I have one question:
Is it enough to back up the .kde folder *ignoring* the akonadi
mysql database?
I don't think emails are stored in .kde any more, instead they are stored in
the .local/share folder in .local_mail_directory.
Or will I have some mails lost?
As far as I understand it your physical emails are still stored in a
folder (maildir) or file (mbox) somewhere. The location might differ
depending on the age of your installation and upgrades gone through etc.
Currently the default is HOME/.local/share/local_mail and
HOME/.local/share/.local-mail.directory.
The akonadi and nepomuk stuff are "only" databases related to "just
about everything". I once deleted all akonadi stuff and boy was I happy
to have a backup to restore. All accounts, settings etc. seem to be in
akonadi "somehow" but the raw data is still in folders.
Nepomuk seems to be more about "only" searching/indexing things. I have
several times deleted the nepomuk folder when search simply stopped
working. Give it time to reindex and all is back where you left.
If you also use Windows I would say Akonadi is a bit like the registry.
Delete it and you basically have to start all over with settings,
accounts etc. Like a fresh install - but your files are still there.
Others may agree or disagree but I generally do not touch the akonadi if
I can avoid it, I just backup all I can of HOME folder and subfolders.
