It produces it just when required so that there will not be unneeded restore points.

Can the System Volume Information folder be deleted?

No. This Folder is not just the System Restore snapshots store folder. Because it consists of info and metadata utilized by Backup, Volume Shadow Copy, and Browse indexer, this folder should not be deleted, especially if it’s a system drive or the drives which are included in Windows Search index.

On USB flash drives and SD cards, you might delete the folder if you don’t plan to include its locations in the Explore index. However, this is recommended leaving the folder as it is even on external drives, as it takes not much disk space. As the folder is hidden and protected (attributes: System + Hidden), it won’t be much of an inconvenience.
