Snapshots and Volume Maintenance

Do we need to un-mount volumes to take a snapshot?

Is it necessary to un-mount volumes before taking a snapshot? How are snapshots related to volume maintenance?

Answer:

No, volumes do not need to be un-mounted to take a snapshot. Snapshots are point-in-time copies of volumes that do not require the volume to be unmounted or interrupted in any way.

So, what exactly are snapshots and how do they work? Snapshots are essentially point-in-time copies of volumes. They allow for the creation of backups or copies of volumes without the need to interrupt access to the volume or dismount it. This means that you can take a snapshot of a volume while it is still actively being used, making it a convenient tool for data protection and recovery.

Think of snapshots as freezing a moment in time for your data. Just like taking a picture allows you to preserve a specific moment, taking a snapshot enables you to capture the state of your volume at a particular point in time. This can be useful for creating restore points or backups that you can revert to if needed.
