b) whether backups will be manual or scheduled
c) backup retention, backup storage, and backup rotation scheme to include who is online at scheduled backup time

Using Loopback Command

Loopback filesystem support allows a user to mount an ordinary file as if it were a device, such as /dev/hda1. This is useful for mounting a CD-ROM filesystem to populate and test before burning it to CDROM.

Use the dd command to create file large enough to contain the filesystem:

dd if=/dev/zero of=filesystem.img bs=1M count=20

Associate the new file with the loopback device:

losetup /dev/loop0 filesystem.img

Create a filesystem within the file:

mkfs -t ext2 /dev/loop0

Mount the filesystem:

mount /dev/loop0 mount point
