Powershellist - My backup script

Not really SCCM related, but still useful.  :)

This Powershell script is what I wrote awhile back to backup the entire C: drive to a specified network share.  It prompts to perform a disk check (reboot required) before backing up to ensure there are no bad sectors.  It creates folders based on make, model, and hostname of the computer and outputs the general backup information (hostname, backup date, network location, make, model) to a CSV file on the network share.

$diskch = read-host "Disk check has not been run yet.  Do you want to run a Disk Check now? [y/n] "
IF($diskch -eq "y") {
$text = 'y'
$text | Out-File 'C:\windows\temp\disk_check.tag'
Write-Host "NOTE: Please run this script again to continue backup after the Disk Check."
$text | chkdsk C: /r
Write-Host "Rebooting to run Disk check..."
shutdown /r /t 5
cmd /c pause | out-null
exit
} else {
write-host "Disk check aborted."
}
} else {
Write-Host "Disk check has been performed."
