Maintaining the System C-1$ 3 3 ( 1 ' , ; &0DLQWDLQLQJWKH6\VWHPProper use of preventive maintenance procedures can keep the system in top operat-ing condition and minimize the need for costly, time-consuming service procedures.This appendix contains maintenance procedures that you should perform regularly.'DWD3UHVHUYDWLRQEveryone inadvertently deletes files at one time or another. Also, hard-disk drives canfail after extended use, so it is not a question ofwhether you will eventually lose data,butwhen. To avoid such loss of data, you should regularly make backup copies of allhard-disk drive files. Frequent, regular backups are a must for anyone using ahard-disk drive.6FKHGXOLQJ%DFNXSVThe frequency with which backups should be made depends on the amount of stor-age space on a hard-disk drive and the volatility of the data contained on the drive.Heavily used systems require more frequent backups than systems in which files areseldom changed.Dell recommends that you back up the hard-disk drive at least once a week, with adaily backup of those files known to have been changed. Following these guidelinesensures the loss of no more than a day’s work in the event of a hard-disk drive failureor if you inadvertently delete one or more important files.As further insurance against data losses, you should keep duplicate copies of theweekly and monthly backups at an off-site location. Doing this ensures that you loseno more than a week’s work, even if one of the on-site backups becomes corrupted.%DFNXS'HYLFHVTape drives are fast, convenient, and reliable devices that can back up data at rates ofup to 1.5 megabytes per second (MB/sec) (sustained, without data compression) andcan often run unattended. Dell offers tape drives with storage capacities in the rangeof 20 to 70 gigabytes (GB) (when available) per tape cartridge and recommends thesedrives and their associated backup software for use as system backup devices. |
