Frequent saving to disk, using your software is the first step. Also, do not reboot your computer while working on a file. Always exit to DOS at the end of the day. You will see the main menu.
Remember that computers are just mechanical devices. It is only a question of when they will eventually ear out. Therefore we are using a system of backing up so that we remember the old saying:
Don't have all your eggs in one basket.
Don't have all your files on one disk.
Use an Off Site Backup Service like ours
| Category | Process | Problem | WEB BASED | Tape | 
| PERFORMANCE | Backup | Backup windows is growing | FAST - Advanced delta processing technology means you send only your changed data, saving your precious bandwidth and shrinking your backup window | SLOW - Must read and write all data to create a full backup | 
| 
 | Restore | Takes too long | FAST  Incremental backups are patched for you. All you have to do is pick the file or files you wish to restore, select a date, and the software does the rest. | SLOW  Admin. must identify media, retrieve internally or from offsite vendor, gain access to a tape device to restore from, then search media for applicable data to start the transfer | 
| 
 | 
 | Too complicated | DISASTER READY  Begin restoring as soon as you realize there is a disaster. If need be, a Mobile vault with all your backup data can be shipped to any location in as little as 90 minutes | ITS A DISASTER  Long lists of media must be created and sent to offsite vendor, where tapes are picked and shipped | 
| 
 | 
 | Requires too much hardware | PROTECTION There is no hardware on-site to deal with. | PROBLEM  Tapes could be corrupted, tape drives could stop working. Hardware is expensive. | 
| RELIABILITY | Verification | Takes too long | FAST  On-the-fly, multi-level data integrity checking eliminates re-read | SLOW  Must re-read all data and compare against data written to tape | 
| 
 | 
 | Its not complete | TWO-WAY  On-the-fly, multi-level data integrity checking performed during backup and restore | ONE-WAY  Integrity checking done only for data written to tape as second phase of backup process | 
| 
 | 
 | Is my data ok? | TESTABLE  Tests on backup data can be performed quickly and easily at any time | UNTESTED  Testing validity of tapes is time consuming and costly. Frequently, its just not done | 
| 
 | 
 | Flawed design | VALIDATED  On-the-fly multi-level data integrity checking ensures your backup are valid | INVALID  Since data often changes between the backup and compare process, numerous errors turn up that are often ignored | 
| 
 | Failures | Not resilient enough | RESUMES  Transport issues with a vault during backups and restores automatically reconnect on user configurable time intervals. the backup resumes | HALTS  Recording issue with tape can often cause backup or restore to be incomplete. Depending on the problem, the tape may get corrupted. | 
| ACCESSIBILITY | Backup | Bottleneck | MULTI-TASKING  Many concurrent jobs can be executing at once | CONTENTION -Must have one tape drive for every job you wish to run | 
| 
 | Restore | Tape formats change | FLEXIBLITY  There is no chance of media obsolesce when using disk to disk backups | OBSOLECENSE  Media formats change to accommodate expanding storage requirements. Most formats are not backward compatible | 
| 
 | Manage | Operate Anywhere | WORLDWIDE  Backups can operate over any IP network, preferably a connection that is broadband or greater. | LAN ONLY  Because tape backups write large volumes of data they have to be local, which makes WAN backups resource consuming and complicated to set up | 
| SECURITY | Authentication | Anybody can read the tapes | STRONG  Incorporates a three-part account, system identification and password scheme for each backup server | NONE  Typically, no authentication required to read a tape except a possibly a label password | 
| 
 | Encryption | Access to the desktop means access to your data | NOT TRUE  You can set passwords that use government standard encryption algorithms just to open the program | TRUE  If you have access to the PC running the backup software, you have access to all corporate data. | 
| Storage Space | Cost per Month | Cost per Year | 
| 1 Gigabyte | $10 | $108 | 
| 2 Gigabytes | $19 | $214 | 
| 3 Gigabytes | $28 | $322 | 
| 4 Gigabytes | $37 | $429 | 
| 5 Gigabytes | $46 | $535 |
