有谁知道如何fsarchiver
仅备份单个 BTRFS 子卷?
将要这机制工作?
1. Mounted the snapshot in /mnt:
mount -t btrfs -o subvolid="id" /dev/sda2 /mnt
2. chroot snapshot:
mount --bind /dev /mnt/dev
mount --bind /proc /mnt/proc
mount --bind /sys /mnt/sys
mount --bind /media/fsbackup /mnt/media/fsbackup
chroot /mnt
3. Fsarchiver backup from btrfs snapshot
fsarchiver savefs -Av -s 2400 -z 2 /media/fsbackup/backup.fsa /dev/sda2 \
