Managing Disk Storage

Basic Disks

Disks are divided into partitions.

Primary partition: One active per disk; bootable; one drive letter.

Extended partition: Uses space not used by primary; one per disk; divided into logical drives; not bootable.

Each disk is a single partition; contains one or more volumes.

Simple volumes: FAT, FAT32, or NTFS; can be resized dynamically.

Spanned volumes: Treat 2-32 disks as single volume; data stored sequentially; not fault tolerant.

Striped volumes: Treat 2-32 disks as single volume; data is interleaved between disks; not fault tolerant; faster speed.

Can be set for all users or individual users

Set from Quota tab of Disk Properties

Quota Entries window displays quotas; monitors users

Dynamically encrypts files with public-key encryption.

Files are decrypted dynamically when accessed by valid user.

Set for folders in General tab of Properties.

Decrypt by turning off encryption option.

Normal (full backup): Backs up all of the files on the volume, regardless of when files were modified, and clears the archive bits
Incremental backup: Backs up all of the files that have been modified since the last backup and clears the archive bits
Differential backup: Backs up all of the files changed since the last full backup; does not clear the archive bits
Copy: Similar to a full backup, but does not clear the archive bits
Daily copy: Backs up all files modified on the current date; does not modify archive bits
