1. U3A 1 How To Backup CD/DVD, Memory Stick, Memory Card, 2nd hard drive, auto

2. U3A 2 Backup: Make a copy of Data, Software, or even an entire Disk, on another medium, possibly in a remote location or on an Internet Server

3. U3A 3 Commercial Practice: “RAID” systems----put everything on more than one disk, all the time. Daily (nightly) System Image to remote site---copy the WHOLE computer system, software and data, exactly as-is. Regular “Incremental Backups” throughout the day---keep “updating” the backup.

7. 7 IF you feel it to be necessary, you can use some of this software to make Disk Images, or more selective Backups, and schedule them to run automatically.

8. U3A 8 Where to? (and how big is it?)

9. U3A 9 Internet Servers----very slow upload. CD/DVD----not much capacity. Memory Stick/Card----very expensive per Gb. Additional/External Hard Disk----£50 for 1000Gb?

14. U3A 14 A simple backup program using “XCOPY”.

15. U3A 15

16. U3A 16 Using the “xcopy” command for an “incremental backup”. xcopy "c:\Documents and Settings\user\My Documents\*" "archive\user\*" /D/I/C/E/Y >> backup.log The first run copies everything. Subsequent runs will only copy files that have changed, or been added, since last time. NB: it wont delete files that have been removed since the last run. It makes a “log file” of what it has done.

17. U3A 17 /D Copies only those files whose source time is newer than the destination time. /I If destination does not exist and copying more than one file, assumes that destination must be a directory. /C Continues copying even if errors occur. /E Copies directories and subdirectories, including empty ones. /Y Suppresses prompting to confirm that you want to overwrite an existing destination file.

18. U3A 18 Backup.bat

19. U3A 19 Backup.bat copies the “current user’s” “My Documents” folder and sub-folders onto the drive you run backup.bat from. Next time it is run, it will only “update” the backup, not re-copy everything. Backup.bat makes a folder “Archive” and then a sub-folder named for the “current user”, so a different user’s backup will go into a different sub-folder. You must make sure that everything you want to keep is in “My Documents” and that the backup drive is big enough to hold the copy.

20. U3A 20 if not exist archive\nul md archive if exist archive\backup_log.log del archive\backup_log.log if exist "%USERPROFILE%\my documents\*" xcopy "%USERPROFILE%\my documents\*" "archive\%USERNAME%\*" /D/I/C/E/Y >> archive\backup_log.log if exist "%USERPROFILE%\documents\*" xcopy "%USERPROFILE%\documents\*" "archive\%USERNAME%\*" /D/I/C/E/Y >> archive\backup_log.log
