is there a way to export registry key but in an incremental way , many copies ?

[drugo]

Hi

i would to export some registry key with a bat file but in incremental way  (keep many reg files , with a name and a suffix for example export1.reg export2.reg and so on ) ?

I 'm thinking about a bat file ,just because i can use the windows 11 or 10 task manager and run every x hours or every day

i don't want to export the entire registry but only 1 key or 2 ,with all the subkeys and keep all them

I use a free portable backup jubut portable , cool program ,but only for files, and macrium for image

i'm looking for a script / bat , can a script/bat file do it?

I have't found a free program to export them

thanks

hi Cacoe

may i a question ?

let's say i want to backup these keys 

Quote

HKEY_CURRENT_USER\Software\Mozilla

to X:\backupregistry

is your script correct ?

I have added HKEY_CURRENT_USER\Software\Mozilla 

the backup folder is X:\backupregistry

about the number of registry key to export what does it mean how many backups?

## Export registry key

# Specify registry key
$registryKey = "HKEY_CURRENT_USER\Software\Mozilla"

# Specify the path to save .reg file
$exportPath = "X:\backupregistry\Mozilla.reg"

# Export the registry key
Invoke-Expression -Command "reg export `"$registryKey`" `"$exportPath`""

# Check if the export was successful
if (Test-Path -Path $exportPath) {
    Write-Host "Registry key exported successfully."
} else {
    Write-Host "Failed to export registry key."
}

Save as <filename>.ps1, run with PowerShell.

Hi @binaryzero  @cacoe

if i click on run with powershell it does work ,I have tried even  in power shell ISE and the error translated in English with google translator is

so i opened powershell as administrator windows 11 pro , and copied everything it does create it but only 1 registry backup

i would like to create many backups and only 1

could be make maybe with the bat/cmd  files many files (i have no limit)?

thanks

    # Define the backup file path

    }
    else {
        Write-Output "Failed to create backup for $key"
    }
}

Save as ps1. Create a csv file with the header "RegistryKey", list key paths underneath.

The number is simply the amount of keys you would like to save, so if you know you want to save 5 keys, enter 5, then you will proceed to get 5 prompts for 5 different key locations, then it will save to 5 different files to the backup location.

All entries under each key will be saved to each file.

Would it not make sense to just learn PowerShell? Literally so useful

I don't see the issue, I tested it, it's a batch file, I ran it, set it to only do 1 key, selected a random key and it saved the contents to a reg file. What is not working?

This. 

I provided two code samples, with comments; up to them now...

hi Cacoe

it does not save any reg files...

i have tried even this key with all the sub keys

for /l %%i in (1,1,%numKeys%) do (
    set /p "key%%i=HKEY_CURRENT_USER\Software\J. River"
)

maybe the problem is this

set "baseFileName=export"
set "fileExt=.reg"
set "counter=1"

i should set  ?

set "fileExt=backup.reg" 

thanks pal

Obviously not, as ".reg" is a file extension and "backup.reg" is not.

Save ^ as "BackupRegistryKeys.ps1".

Create a CSV file called "regkeys.csv", save it in X:\Backupregistry, copy and paste the below.

RegistryKey,
HKEY_CURRENT_USER\Software\Mozilla,
HKEY_CURRENT_USER\Software\J. River,

(or use Excel, save as .csv)

Open PowerShell, run the script, .\BackupRegistryKeys.ps1. Tada

When you want to add more registry keys, add them to the csv file. No need to hardcode paths in the script...

[grunger106]

Tidy little script that  -
(+Extra credit for commenting it properly👍)

Still surprises me there is no export-item functionality for the registry in PowerShell, you can do everything else - but for exports you still have to call reg.exe
 

[jupe]

Instead of adding number -01 etc index numbers, you could just use the date, if you did that you could have just a 1 liner, something like this:

reg export "HKEY_CURRENT_USER\Software\Mozilla" "X:\backupregistry\%DATE:/=-%.reg" /y

Depending on your local date format you might need to change the format of the date variable to suit, or add the time variable too if you are doing multiple exports per day.

hi

first i want to thank you so much

but i can't understand why under windows 11 pro 64bit , from the extension menu run with powershell it doesn't work

it's just handy

will the script save me many *.reg files , like backup.reg , backup1.reg , backup2.reg and so on

appreciate it a lot

Added a line to append the date and time to the end of the filename; you can change the format yourself, https://lazyadmin.nl/powershell/get-date/.

You're going to need to run this in an elevated PowerShell (run as administrator) session if you're backing up HKLM keys.

If you want to create a shortcut, create BackupRegistryKeys.cmd and put "start %SystemRoot%\system32\WindowsPowerShell\v1.0\powershell.exe -Executionpolicy Bypass -Noninteractive -File "X:\backupregistry\BackupRegistryKeys.ps1". Right click, run as administrator.
