git-annex can be configured to require more than one copy of a file exists,
|
|
as a simple backup for your data. This is controlled by the "annex.numcopies"
|
|
setting, which defaults to 1 copy. Let's change that to require 2 copies,
|
|
and send a copy of every file to a USB drive.
|
|
|
|
# echo "* annex.numcopies=2" >> .gitattributes
|
|
# git annex copy . --to usbdrive
|
|
|
|
Now when we try to `git annex drop` a file, it will verify that it
|
|
knows of 2 other repositories that have a copy before removing its
|
|
content from the current repository.
|
|
|
|
You can also vary the number of copies needed, depending on the file name.
|
|
So, if you want 3 copies of all your flac files, but only 1 copy of oggs:
|
|
|
|
# echo "*.ogg annex.numcopies=1" >> .gitattributes
|
|
# echo "*.flac annex.numcopies=3" >> .gitattributes
|
|
|
|
Or, you might want to make a directory for important stuff, and configure
|
|
it so anything put in there is backed up more thoroughly:
|
|
|
|
# mkdir important_stuff
|
|
# echo "* annex.numcopies=3" > important_stuff/.gitattributes
|
|
|
|
