Automatic backups in Windows

The following powershell script copies all .docx files from $global:SRC to $global:DEST with a timestamp.

Save this file to something like "StartClone.ps1". Then launch it with "[right click] > Run with PowerShell." Minimize the resulting window.

### Configuration - CUSTOMIZE THESE
$global:SRC = "C:\Users\fil\test"
$global:DEST = "C:\Users\fil\backup"
$global:LOGFILE = "C:\Users\fil\log.txt"


### SET FOLDER TO WATCH + FILES TO WATCH + SUBFOLDERS YES/NO
$watcher = New-Object System.IO.FileSystemWatcher
$watcher.Path = $global:SRC
$watcher.Filter = "*.docx"
$watcher.IncludeSubdirectories = $true
$watcher.EnableRaisingEvents = $true  

$rv=Test-Path "$global:DEST"
if ($rv -eq $False) {
    New-Item -ItemType "directory" -Path "$global:DEST"
}

function global:logging ($text) {
    $logline = "$(Get-Date -uformat "%Y/%m/%d %H:%M:%S") - $text"
    Add-content $global:LOGFILE -value $logline
}

### DEFINE ACTIONS AFTER AN EVENT IS DETECTED
$action = { 
    $path = $Event.SourceEventArgs.FullPath
    $changeType = $Event.SourceEventArgs.ChangeType
    global:logging "$changeType $path"    
    $file = Split-Path $path -leaf
    $now = "$(Get-Date -uformat "%Y-%m-%d %H.%M.%S")"
    $dest = "$global:DEST\$now $file"
    # global:logging "file=$file now=$now dest=$dest"
    copy-item "$path" "$dest"
}    
### DECIDE WHICH EVENTS SHOULD BE WATCHED 
echo "Hello world $global:LOGFILE"
Register-ObjectEvent $watcher "Created" -Action $action
Register-ObjectEvent $watcher "Changed" -Action $action
# Register-ObjectEvent $watcher "Deleted" -Action $action
# Register-ObjectEvent $watcher "Renamed" -Action $action
global:logging Started
while ($true) {sleep 60}
