Re: Question about "btrfs send/receive"

Hi Marc,
     I can`t access /perso/btrfs/2014-03.html on that server. But I 
guess it has similar content as 
https://btrfs.wiki.kernel.org/index.php/Incremental_Backup ?
     If so, I am afraid incremental backup not suitable for a API 
implementation in libguestfs.
     Is the simplest form a usual condition people will use for 
subvolume backup? Is the simplest form make sense in daily life?
