Storage Fundamentals• How much storage capacity do I need?• In two years, you will probably three

times the storage space that you need now

• The use of multimedia greatly increases your need for storage capacity


Back Up Your Files• Save

– your “working”documents, spreadsheets, and database files

– use a backup program to save your e-mail messages if you are in business or if you need to refer to them in the future

– your downloaded updates and releases/versions


Save Your Files

• Save– your favorites (“bookmarks”) in

your browser– your address book– any customizations that you have

performed


Save How Often?• For businesses - daily on servers• For individuals

– often (every few minutes) during file generation

– biweekly or weekly total backup using a backup program


Diskette Storage• Organize, organize,

organize– If it is important enough to

store, it is probably important enough to duplicate in another medium for future use.

– Use labels, and mark them for identification: filename, program used, creator, date

Hard Disks

• What do I need to know for emergencies?


Hard Drive Emergencies• When installing a hard disk or a new

system– write down the current configuration and

save along with other important documents such as sales slips, installation instructions

– the configuration information should include cylinders, tracks, sectors, and whether an additional software disk manager has been used


SCSI

• SCSI (pronounced “scuzzy”)– there are many different standards– recommend going to the manufacturer’s site

and obtaining the hard drive and adapter’s standard

– note the type of SCSI– note the SCSI cable required, including number

of pins used


EIDE• Only one master and one slave hard drive per

IDE port• Ensure the correct jumper setting is enabled

before booting the system with the new hard drive

• Depending on the BIOS, adjustments within the CMOS may be necessary– on startup, use the appropriate key for access. It

could be the delete, ESC, F1 key, or others


Additional Types of Backup• ZIP or other large-capacity

recordable media• CD-R or CD-RW• A second hard drive, internal or

external– file backup is accomplish by drag-and-

dropping to the second disk


Backup

• Internet backup– many people are using free or fee-

based Internet services for backing up systems and files

– allows access to files even when you are not at your computer

– security and privacy need to be ensured
