Hi there!
I'm new on btrfs, and I like it :)
But i have a question. I have a existing backup on an external HDD. This
was ext4 before i converted it to btrfs.
And i installed my debian new on btrfs with some subvolumes. (f.e. home,
var, multimedia/Video multimedia/Audio...)
On my backup there are no subvolumes.
Now i wrote a script to take local snapshots on my laptops HDD an mirror
this snapshots with btrfs send/receive to the external HDD.
An i don't know, how to do, to make the inital snapshot on the external
HDD. I want to use the existing data there, so I don't have to transmit
the whole bunch of data to the external drive, which exists there
already...
What happens, if i make the same structure on the external drive with
creating subvolumes and »cp --reflink«, give this subvolumes the correct
names, and fire a »btrfs send«?
Or is the best (ONLY???) way, to make an initial snapshot on the
external drive and delete the old backup there?
greetings
jakob
