practically test the "from borg" importer

[ThomasWaldmann]

I have just added some code to import backups from a borg 1.x repo into a new borg 1.x repo.

borg-import borg -h  # read this!

Importing an archive does:

• for each archive in the source repo
• extract archive to the extraction directory (subdirectory of cwd)
• create a new archive from the extracted data
• delete all files from the extraction directory

This is useful when there is some reason to rebuild the repo:

• use a new AES key (e.g. if your old key might be compromised)
• you can also transfer archives from multiple source repos into a single destination repo
• (add more reasons here)

There is a automated test that succeeds doing this, but more practical tests are definitely needed. Be careful!

It keeps asking for the passphrase of the 2 repositories. If you have the same passphrase on both repositories, setting BORG_PASSPHRASE works fine, though.

It's pretty slow but there's probably not much that can be done about that.

Otherwise it seems to work fine.

is the issue still open if you provide me with more details i can work on fixing it

@abahor Thanks for working on this.

Just read the top post and start from a source repo that has multiple non-empty archives.
