tar command
Does anybody know something about tar?
Very interesting, I deleted a broken Maverick-Natty-Upgrade-Install by # rm -r *, then I copied a backup archive and restored Maverick from the backup by tar xzf *, restoring Maverick takes between 3 and 4 minutes only. How is this possible? The restored Maverick seems to be ok, at least Email etc. is ok, the size, 6.76 GiB is correct. An amazing voodoo trick. I didn't know that it's that fast. -- Ubuntu-Studio-users mailing list Ubuntu-Studio-users@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-studio-users |
tar command
tar has been around for as long as *ux.
So it's had plenty of time to mature. As with many of the vintage *ux cammand line utilities it can be cryptic and not necessarily intuitive to use.

tar command
This worked because the MBR, partition table, and file systems were
intact. What you were doing was a simple file copy (tar can preserve file permissions) so that the only real obstacle was disk I/O. If you have a more serious failure, a simple tar will not be enough.
