Remove Snapshot by name

JGPSHNTAP — Thu, 05 Jun 2025 06:31:13 GMT

In our environment we sometimes get stale SME snapshots that start with {.

So here is a little powershell script that will loop through all the filers and remove it.

[Code]

### Mail "constants"

$sendMailAs = "x"

$recipients = "X"

$subjectLine = "GUID LOG"

$mailMessage = "GUID Report The Attached Snapshots have been removed from the filers."

$smtpServer = "X"

$priority = "high"

### File Constants

$date = (get-date).toString('dd-MMM-yyyy_h-mm-ss')

$ext = ".log"

$outfile = "Exchange_GUID__" + $date + $ext

$delim = "`t"

Import-Module DataONTAP

$hostfile = "exchange.txt"

gc $hostFile |% {

$nacontroller = Connect-NaController $_

Get-NaVol | Get-NaSnapshot -SnapName "{*" | select TargetName,Name,Created,Total,CumulativeTotal | ft @{Expression={$nacontroller};Label="Filer name";Width=20},@{Expression={$_.TargetName};Label="Volume";Width=40},@{Expression={$_.Name};Label="Name";Width=40},@{Expression={$_.Created.ToShortDateString()};Label="Created";Width=12},@{Expression={ConvertTo-FormattedNumber $_.Total DataSize "0.0"};Label="Total";Width=10},@{Expression={ConvertTo-FormattedNumber $_.CumulativeTotal DataSize "0.0"};Label="Cumulative";Width=10} | Out-File -filepath $outfile -append

get-navol | get-nasnapshot -snapname "{*" | where-object {$_.busy -like "*false*"} | remove-nasnapshot -confirm:$false

}

## Send Email

Send-MailMessage -To $recipients -From $sendMailAs -Attachments $outfile -Subject $subjectLine -Body $mailMessage -Priority $priority -SmtpServer $smtpServer

[/code]

Now, i'm not sure its the best way to do this, but it works. I wanted to ensure we weren't trying to delete busy snaps so I through in $_.busy -like "*false*". I tried -eq "false" but it wouldn't return anything which was confusing to me .

Now remember i'm very new to powershell so any criticism is welcome. I didn't know a good way to log in one line and then delete in another so, I had to run the cmdlet again. Any suggestions for imporvement are welcome.
