I looked around for something to create and manage daily snapshots and didn't find anything, so I wrote this. Thought I'd share in case others might use it.
cd 'C:\Program Files (x86)\VMware\Infrastructure\vSphere PowerCLI\Scripts'
.\Initialize-PowerCLIEnvironment.ps1
Connect-VIServer localhost | Out-Null
$date = Get-Date
$datef = Get-Date -format s
if ( $date.Day -eq 1 ) {
$name = "Monthly $datef"
} elseif ( $date.DayOfWeek -eq "Sunday" ) { $name = "Weekly $datef"
} else { $name = "Daily $datef"
}
Get-Folder "Production Servers" | Get-VM | New-Snapshot -Name $name -Quiesce
Get-Folder "Production Servers" | Get-VM | Get-Snapshot | Where-Object { `
( $_.Name -like 'Daily*' -and $_.Created -le $date.AddDays(-7) ) ` -or ( $_.Name -like 'Weekly*' -and $_.Created -le $date.AddMonths(-1) ) ` -or ( $_.Name -like 'Monthly*' -and $_.Created -le $date.AddYears(-1) ) `
