how to backup a text file every hour in windows 7

[batemanj]

Hello,

I have windows 7 Pro on my laptop and I need to automate backup of a text file every hour with unique backup file name with date stamp.

For ex. My file name = scratch.txt and the backup file name should be scratch-201807210100 (at the time of 1:00 hours) and scratch-201807210200 (at the time of 02:00 hrs) and so on...

Please advise me on how to do this? I'm admin of this laptop.

Thanks!

Create the batch file and then open up Windows Task Scheduler to create a scheduled task that repeats every hour.

Thanks I should have been more clearer.

I know a batch script and keeping it in task scheduler would do but I dont know anything about batch scripting. Appreciate if someone could provide it.

Code: Select all

@echo off
FOR /F "tokens=2 delims==.-" %%G IN ('wmic os get localdatetime /value') DO SET "dt=%%G"
set "dt=%dt:~0,12%"
copy "scratch.txt" "scratch-%dt%.txt"

Many thanks Squashman

It worked like charm with time stamp of minutes as well.

Best regards,

It's working if i run the batch file from command prompt but not working from task scheduler because of lack absolute paths of the scratch file.

I tried to change it to copy

Code: Select all

"d:\scratch.txt" "d:\scratch-%dt%.txt"

but this not working. Could you please modify it to set absolute paths?

Thanks!

Your example is an absolute path.
