This article mainly introduces how to use batch backup directory in windows. It is very detailed and has certain reference value. If you are interested, you must finish reading it.

The following is a bat batch script that needs to back up files, backing up the files under yesterday's C:\ Users\ Administrator\ Desktop\\ 111\ 2020\ 03\ 05 directory

If you need to write a batch file, first consider the need to get yesterday's date, and create a date directory to store the backup, and check the number of files to back up and the size of the file.

The number of files backed up is compared before and after. The code is as follows:

Rem: "author is czb"

Rem: "create scripts time 2020-03-05"

@ echo off

Set date_time=%date:~0,4%%date:~5,2%%date:~8,2%_0%time:~1,1%%time:~3,2%%time:~6,2%

Set suiji=%random%

Echo initing.

Rem: "get yesterday's time"

@ echo off

Set YE=%date:~0,4%

Set MO=%date:~5,2%

Set DA=%date:~8,2%

Set DG=1

Set/a vY1=%YE% 400

Set/a vY2=%YE% 4

Set/a vY3=%YE% 100

If vY1%==0 (set var=true) else (if% vY2%==0 (if% vY3%==0 (set var=false) else (set var=true)) else (set var=false))

Set LY=%YE%

Set LM=%MO%

If MO:~0,1%==0 (set MO=%MO:~1,1%)

If DA:~0,1%==0 (set DA=%DA:~1,1%)

If DA% GTR DG% (set/a LD=%DA%-%DG%) else (

If% MO%==1 (set/a LY=%YE%-1) & (set/a LM=12) & (set/a LD=31+%DA%-%DG%) else (

Set/a LM=%MO%-1

If MO%==3 (if var%==false (set/a LD=28+%DA%-%DG%) else (set/a LD=29+%DA%-%DG%))

For% an in (2 4 6 8 9 11) do (if "% MO%" = = "% a" (set/a LD=31+%DA%-%DG%))

For% b in (5 7 10 12) do (if "% MO%" = = "% b" (set/a LD=30+%DA%-%DG%)
