[comp.unix.xenix] hard disk as archive

ron@mlfarm.UUCP (Ronald Florence) (08/06/89)

I would appreciate advice on using a second hard disk as a backup
device.  (This is not a "mirroring" setup.)  The first hard disk is
divided into two file systems: root and /dev/u.  The second hard disk
is a single system: /dev/archive.  Can and/or should I use the restore
and backup commands?  Cpio?  Or should I use the copy command to
create a copy of the root and /dev/u filesystems on /dev/archive?

Thanks in advance for any suggestions or comments.

The backup command works on individual file systems so if you were
to use it your second disk must be in two parts also, one for each
of the fs's on the first disk.  Also, restoring a single file from
a backup done this way is  is "moderately" difficult.  Given that
the second disk is a single system and that cpio will work in the
"hierarchical" directory structure, my choice would be cpio.

I would not tend to use the XENIX copy command since it would
require a file system structure as its destination, which would
need to be mounted onto the existing structure, which could lead
to loops if your are not careful.

Hope this is helpful  :-)
