Incremental versus full filesystem backups

Hi,

Any thoughts on incremental as opposed to full file system backups of the Filestore where reports are stored.

We have a full backup of our FRS but anothere systme currnetly only has incremenatl backup of FRS. (i.e. what changed between one day and the next)

A third-party backup tool.

Any thoughts reagrding full versus incremental filesystem backup.

Suspect full safer (we have our cms alos backed up).

Thoughts?

Thanks

Philip
