delete snapshots - keep snapmirror

JSHACHER11 — Thu, 05 Jun 2025 05:49:01 GMT

hi guys,

I am trying to delete all snapshots older than 2 days and that don't have @snapmir@ in them

I was trying this but 'whatif' tells me that the snapmirror snapshots will still be deleted

Get-NaVol | Get-NaSnapshot | where-object {($_.Created -lt (Get-Date).AddDays(-2)) -and ($_.name -ne "@snapmir@*")} | remove-nasnapshot -whatif

here's an example of a snapmirror snapshot I want to keep:

@snapmir@{8DEC61ED-452A-4B21-8EDE-18503B0A2E37}

what am I doing wrong?

thank you

Joel

Hi Joel,

I think you might want to use -notlike instead of -ne so the wildcard is evaluated.

I just did a quick test:

PS C:\> '@snapmir@{8DEC61ED-452A-4B21-8EDE-18503B0A2E37}' -ne "@snapmir@*"

True

PS C:\> '@snapmir@{8DEC61ED-452A-4B21-8EDE-18503B0A2E37}' -notlike "@snapmir@*"

False

I hope that helps!

Steven,

'whatif' showed no issue but when I actually try to delete I am getting this:

VERBOSE: Deleting snapshot exchsnap__ex_08-30-2013_19.05.47__daily from volume exch2_1.

any ideas?

cheers

Does anything from Thread Link : 12737 help? It's possible a restart of the PowerShell session or host might resolve it.

Steven, is there something you don't know?
