In our unit, there are some old employees who are not very good at using computers. They often put important files on the desktop, and plus the computer often has problems, all important data are completely lost~ Although we have reminded them many times not to put them on the desktop, they just don't pay attention, which is very headache~

So I wrote a batch file and put it in the startup item, so that the desktop files are automatically backed up every time the computer starts

xcopy "E:\Documents and Settings\wind" /e d:\backup

After execution, there will be an option <yes/no/all?> asking whether to rewrite (overwrite) the previous data. It was originally a matter of just pressing "a", but those old-fashioned people even said it was troublesome and didn't know how~

The problem I need to solve is how to not display <yes/no/all?> and directly execute it~


I am a novice, just started to contact DOS, please give me some advice, great gods~

echo a| xcopy "E:\Documents and Settings\wind"/e d:\backup

Does the `xcopy` command have a parameter to force overwriting without prompting? Just add the parameter `/y`.

Hehe~ So there is this function~ Thanks

I wrote a simple batch script to back up the desktop and My Documents files when the computer starts, as follows:

@echo off
xcopy "E:\Documents and Settings\wind\Desktop" /e /q d:\backupd\Desktop /y
xcopy "E:\Documents and Settings\wind\My Documents" /e /q d:\backupd\Documents /y

This batch script can execute normally, but after using it for a while, the problems are found:
1. It automatically backs up every time the computer starts. Sometimes it restarts several times a day, and there are many files, which takes time. How can I set it to back up once a day?
2. Files that have been deleted are still present in the backup files. As other new files are added, the backup data becomes larger and larger over time, and it is cumbersome to delete manually. Can it be set to keep the backup files consistent with the original documents? (That is, files deleted in the original documents can also be automatically deleted in the backup files)

This question shouldn't be too difficult, right? :( Please give me some pointers.

May I ask if it is possible to set it so that the backup files are consistent with the original documents? (That is, if the original document has been deleted, the backup file can also be automatically deleted)

I want to generate an xcopy date to complete the synchronous deletion using the date.

Using the backup program that comes with XP (Start -> Accessories -> System Tools -> Backup), if everything is solved with batch processing, why use XP?

@echo off

"C:\Program Files\WinRAR\RAR" u -ep1 -r -m0 d:\backupd\桌面.rar "E:\Documents and Settings\wind\桌面\*"

"C:\Program Files\WinRAR\RAR" u -ep1 -r -m0 d:\backupd\文档.rar "E:\Documents and Settings\wind\My Documents\*"

Use RAR to compress and back up!

The following updates and backs up the files that have changed.

@echo off

"C:\Program Files\WinRAR\RAR" u -ep1 -r -m0 d:\backupd\桌面.rar "E:\Documents and Settings\wind\桌面\*"

"C:\Program Files\WinRAR\RAR" u -ep1 -r -m0 d:\backupd\文档.rar "E:\Documents and Settings\wind\My Documents\*"

Compression ratio adjustment
-m0 Store Do not compress files when adding to the compressed file.
-m1 Fastest Use the fastest method (low compression)
-m2 Faster Use the quick compression method
-m3 Standard Use the standard (default) compression method
-m4 Better Use a better compression method (better compression but slow)
-m5 Best Use the maximum compression method (best compression but slowest)

Excuse me, the person on the second floor, how to generate an xcopy log? Can you make three files, such as a, b, c. On the first day, back up to a. On the second day, also back up to a, and the first day's automatically transfer to b. On the third day,... That is, one backup keeps three days.

The meaning of the building owner on the 5th floor, I don't understand. Can you explain it? I'm still a newbie~

Re forrestzheng01:

A more effective and quick way is to relocate the user's desktop directory to the specified data disk. This can be achieved using optimization tools such as Super Rabbit, or by modifying the relevant key values in the registry through a registry script or batch processing.
