Backing Up Your Computer
Presentation to the EPICUG, Inc., 9/16/98
There are two kinds of hard disks -- the ones
that have failed catastrophically and the ones that are going to fail catastrophically!

Backups of some shape/form are essential if you do anything
serious on a computer. Could you afford to lose:
 | Financial records |
 | Accounting data |
 | Customer data |
 | Contacts |
 | Letters and documents |
 | Photos |
 | Email |
 | Projects |
 | Books in progress |
 | Databases |
 | Notes and ToDo lists |
 | Appointments |
 | Spreadsheets |
 | Tax info |
Some things to do to avoid even needing backup: (this doesn't mean that you don't
need to backup!)
 | Use surge surpressor or better yet, |
 | Get a battery backup system (UPS); Avoids power failures and related disk
crashes |

 | Avoid moving your system around; never move when its turned on |
 | Dont let unauthorized, unskilled, or unknown people access your system (they
could intentionally or accidentally delete things) |
 | Periodic antivirus checks |

 | Note that some data from some crashed hard disks can be recovered, usually at great
trouble/expense. |

You cant afford NOT to backup!
What to backup
 | Data only: just periodically copy the important files to floppies or removable
disks, or even a second hard disk (chances are low that BOTH hard disks will fail
together). |
 | Total system backups: all hard disk files are backed up to floppy (yuk), removable
storage, or tape. |
 | Total system backups are rarely as useful as you think often, programs have
to be reinstalled anyway when a disk is replaced. |
Backup hardware
 | Floppies; rare for system backups; usually for storing small individual files as
they are created. |
 | Removable drives: Jaz, Zip, Syquest, Bernoulli, MO, CD-R/RW |
 | Often overlooked: a large additional hard disk; having data on two drive
"spindles" is much safer than just one |
 | Tape drives: common and pretty cheap; fairly fast to backup; fairly slow to
restore. |
 | Online storage: companies that provide storage areas on their sites; better for
smaller collections of highly critical data you need stored off-site fairly frequently. |

Backup Media
 | Floppy disks (1.44M usually) |
 | Zip |
 | Jaz |
 | Syquest |
 | Tape (QIC, DLT, DAT) |
 | Online storage |

Backup Software & Utilities
 | Windows95/98 and NT include a "free" backup utility, usually can write to
floppy, hard disk, removable disk, or (some) tape drives |
 | Many third party solutions: Seagate Backup, Novaback, Cheyenne. Some software will
"compress" data to as much as double the space on your backup media |
 | You could use compression programs (like Zip, Winzip or Stuffit) to save space on
floppies or storage media. |
 | Some utilities can back up critical system files (registry, etc.). Examples are
Norton Utilities, Nuts and Bolts, etc. |

Backup Strategies
 | Backup early and often. Even if you save your work every hour, you could still lose
an hours worth of work! |
 | Daily backup at least of important work |
 | Could backup only important stuff |
 | Could do regular backups of entire areas without regard to whats changed |
 | Rotate your backup media so you have several versions of backed up files. |
 | Always store a copy of your critical backups "off-site" (so if your home
or business is destroyed you have some version of the info) |
You cant afford NOT to backup!
