backup & restore a partition using cpio from compressed .gz file

[ccc]

hi

I've saved a big /usr partition using cpio instead of .cpio into compressed .gz file:

# cd / ; find ./usr -depth -print -xdev | cpio -ovfB | gzip -c > /mnt/backup_usr.gz &

Normaly I can recover from a .cpio file using:

# cpio –ivdmlu < /backup_usr.cpio &

My question is, how it works to recover from a compressed .gz file?

Something like this perhaps?

zcat backup_user.gz | cpio -ivdmlu

And using > is wrong/useless, as I have already mentioned in an older thread.

sorry, for a mistake you're right!

other way:

# cd /;gunzip </mnt/backup_usr.gz | cpio -ivdmlu

Using a recent version of FreeBSD, just use tar(1):

tar xvpf /mnt/backup_usr.gz -C /
