Not necessarily. First, Microsoft doesn't support network-based PSTs. It
can lead to data loss and corruption of the PST. Second, if you leave
Outlook open, the PST cannot be reliably backed up. A good backup can be
made only when Outlook is closed. The best way is to use the PFBACKUP tool
from Microsofty and then move that backup copy to the network folder.

Which is the correct way.
