I have problem with backup ramfs/tmpfs to solid/regular disk.
I prefer backup those ramfs/tmpfs using "dd" command instead of "cp" command, so I don't need care about a lot of files, contain of files/dirs and permissions.
as I know backup using dd need two params: origin disk/file and destination disk/file. disk usually identified by something in /dev.
for ramfs/tmpfs I dont know how to dealing with, since I cannot found those type of disk/file under /dev nor dmesg.
root@debian:/etc# cat /etc/fstab
none /mnt/tmpfs tmpfs size=1G 0 0
root@debian:/etc# mount -a
root@debian:/etc# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda1 953M 702M 203M 78% /
tmpfs 1.5G 0 1.5G 0% /lib/init/rw
udev 1.5G 96K 1.5G 1% /dev
tmpfs 1.5G 0 1.5G 0% /dev/shm
none 1.0G 0 1.0G 0% /mnt/tmpfs
do somebody ever had this similar cases?
really appreciated for your kind of answers.
