1. Make a local file named as “backup_disk.img” and initialize an “ext4” filesystem in the file whose capacity is about 50MB with 512 Byte block size. The filesystem in the “backup_disk.img” file is mounted on the local directory “backup_disk”.

- List the required commands

- Evaluate your operation by using “ls –hl backup_disk.img”, “df –T backup_disk”, and “ls –hl backup_disk”

2. Make a local file named as “backup_disk_2.img” under the directory “backup_disk” where the filesystem of “backup_disk.img” is mounted. And Initialize an “ext3” filesystem in the “backup_disk_2.img” file whose capacity is about 1MB with 1024 Byte block size. This filesystem is mounted on the local directory “backup_disk_2.

- List the required commands

-Evaluate your operation by using “ls –hl backup_disk/backup_disk_2.img”, “df –T backup_disk_2”, and “ls –hl

backup_disk_2”

3. Let’s assume that a file “a” locates under “backup_disk”, a file “b” locates under “backup_disk_2” and a file “c” locates in the local directory. Evaluate whether the following operations correctly works or not. (Assumption: the local directory is the parent directory of “backup_disk” and “backup_disk_2”. The following commands are executed on the local directory.)

1) ln c c_h

2) ln –s c_s

3) ln backup_disk/a a_h

4) ln –s backup_disk/a a_s

5) ln backup_disk/a backup_disk/a_h

6) ln –s backup_disk/a backup_disk/a_s

7) ln backup_disk_2/b backup_disk/b_h

8) ln backup_disk_2/b backup_disk_2/b_h

9) ln –s backup_disk_2/b backup_disk/b_s
