Snapshot question

When a snapsnot is taken before the machine gets the updates, and if the updates are successful and you would like to proced with the snapshot'd version, do you have to apply the snapshot or just let the machine run as per normal from the snapshot?

Thanks

Never let a VM in a snapshot mode if you can commit the snapshot.

Performance are not as good as normal mode and it's dangerous to let the snapshot growing and growing...

Hope this helps

So if you were going to update a system and wanted to take a snapshot and found that the upgrade was fine, you remove the snapshot and then apply the update again? knowing it worked with the snapshot? or do you commit the snapshot somehow?

Thanks

Hi, if you go into the snapshot manager and click delete then you are merging the changes in the snapshot delta file to the base file system (.vmdk file). If you think about it as a place-holder, the Goto function rolls you back to when the snapshot was taken loosing all changes that were made and delete is you saying "It's ok, I dont need the place holder any more because it's all working".

As previously stated, if you dont need the snapshot, delete it.

Thanks,

Neil

You have to apply the snapshot - if you were to continue running the vm with the snapshot the snapshot log would continue to grow eventually affecting vm performance when it gets to about 1-2 GB -

Yes exactly.

Never let grow a snapshot if you can commit it !

You can have issue during its commit when it becomes too large...
