How to Backup SharePoint Site Collection automatically using PowerShell. !
Site Collections backup can be initiated using the Central Admin Site but in order to have something automated with periodic bases along with notifications need a scripted flow to cover all the requirements.
SharePoint offers a way to perform backups at site collection level using “Backup-SPSite” command. This procedure is designed to take an exact copy of a SharePoint Site and in that case no data will be lost, changed and transformed., the backup file generated more or less as a SQL dump (per-site-bases) of SharePoint content database. It maintains the GUID of every object, except the GUID of the root site. when backup is restored, SharePoint generates a new GUID for the site collection.
