backup, encrypt and then restore

in flag

I would like to encrypt my hard drive, but I have a lot of packages installed and configured already, so I was wandering whether it is possible to save a backup state and then restore it to the system.

My current take is this:

  1. tar everything on my system with a command such as in here:
sudo tar czf /backup.tar.gz \
--exclude=/backup.tar.gz \
--exclude=/dev \
--exclude=/mnt \
--exclude=/proc \
--exclude=/sys \
--exclude=/tmp \
--exclude=/lost+found /
  1. Then load from USB-drive, format and install new system, while encrypting my partitions.
  2. Then untar everything back to the new system.

My questions are: will that work? are there any more convenient ways to encrypt a hard drive while preserving packages and configuration? Are there some caveats I should know about? Can you share your experience?

Thanks in advance.

You can image and restore it later, that has been done since the dawn of computers with hard drives. Installing from scratch and then try to retrofit a full drive image from a previous installation makes no sense. Settings are all inside /home so it makes sense to back it up by any reliable mean. Manually installed packages can and should be reinstalled. It's easy to output a list of user installed packages (and additional repositories if needed) to a file and then, in the freshly installed system, use one or just a few command to reinstall everything (settings then can be retrieved from /home

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
