help with backup

garbanzo · #1 Post by **garbanzo** » Mon Aug 18, 2008 4:33 am

i find myself needing to backup the contents of a particular folder when i start my system. preferably with winrar. i would also like to be be able to automatically delete any backups more than 10 days old.

anyone know an app that can achieve this? or a batch file or script?

thanks!

You have to add deleting old ones yourself.

EDIT: minor bugfix

Since you have WinRAR and you only want to backup a single folder you don't need all that - you only need one line. WinRAR's help details all of the command line switches.

Here's an example

Code: Select all

"C:\Program Files\WinRAR\winrar.exe" a -r "C:\Path\to\backup_storage\%DATE:~-4%-%DATE:~4,2%-%DATE:~7,2%.rar" "C:\Path\to\folder_to_backup"

This will give you an archive of your folder (the -r switch recurses subdirectories) titled with the date, like 2008-08-18.rar. I got the date format bit from http://cybernetnews.com/2008/01/03/cybe ... e-backups/

I don't know how to do the cleanup.

But this date trick depends on locale.
That's why I use the separate batch - it requires less tweaking and considering that I didn't write it - didn't take much time either.

wow, thank you m^(2), but that is greek to me. i have absolutely no idea how to change that to fit my needs.

i managed to get ashghost's suggestion working, which is a start, but it's the cleanup part that i really need.

perhaps this will help (this does not have to be portable, by the way):

what to archive:
C:\Documents and Settings\All Users\Application Data\GPSoftware\Directory Opus

where to put it:
C:\Documents and Settings\All Users\Application Data\GPSoftware\Backup

edit - i posted this on another forum too, and i've had four people give me batch files, but nothing has worked.

is there an app that will do this??

ashghost · #6 Post by **ashghost** » Mon Aug 18, 2008 9:50 am

I think I found your answer: FORFILES

http://www.ss64.com/nt/forfiles.html

So you would use the following:

FORFILES -p "C:\Documents and Settings\All Users\Application Data\GPSoftware\Backup" /d -09 /m *.rar /c "cmd /c del @file"

I tried it out and it works like a charm for me in CMD.exe

thanks ashghost. i got the same suggestion on the other forum, but we have not been able to get it to work right i'll try your method in the morning, i got things to do now unfortunately...

garbanzo · #8 Post by **garbanzo** » Mon Aug 18, 2008 10:57 am

well here's one i got from another forum and it finally works!

Code: Select all

@ECHO OFF
cd "C:\Documents and Settings\All Users\Application Data\GPSoftware\"

set path="%programfiles%\WinRAR\";%path%
rar a -agYYYYMMDD "Backup\backup.rar" "Directory Opus"

forfiles -pBackup\ -s -m*.rar -d-10 -c"CMD /C del /q @FILE"

thanks for the replies everyone
