Hi,
maybe someone can enlighten me. I am doing btrfs send & receive with full
snapshots and incremental updates.
It basically looks like this:
vol-0 and vol-1 are full subvolume image sends.
inc-1 and inc-2 are incremental images with:
# btrfs send -f inc-1 -p vol vol'
# btrfs send -f inc-2 -p v

I can only speak from experience, a snapshot can take up to a minute
to create later on, so minutely snapshots are out of the question
then... I have snapshots every hour and I have no problems with that
at all :)

Hi,
I'm somewhat confused with who is right on what when it comes to
showing disk usage and space free.
I have a file system that I'm using for testing with a full linux

snapshots and I've also done a lot of changes to the system
On that note, is btrfs doing automatic background scrubs of its own or
do I have to use crontab to schedule scrubs?

That's because the test shouldn't be in your root in the first place.
The common way of thinking now is to create a btrfs volume with a
structure for holding subvolumes inside of which your system root is a
member. You then mount the system root via -o subvol= and will only
see it and nothing else.
If you care about the data, create a backup if you haven't already
done so. Then you can try btrfsck, maybe you are in luck!

Is there any way to get it mounted? Or to extract single files?
