Backing up a network-attached storage system means considering both what gets protected and how recovery works. Compare backup direction with file and folder restore, and check whether database and virtual machine backups are included. Immutable backups and retention limits provide more details to weigh when planning protection. Free-plan availability and paid-from pricing help frame costs. IDrive, Duplicacy, and Acronis Cyber Disaster Recovery Cloud are among the options shown, alongside Duplicati and ElephantDrive. Consider the data types you need to protect and the recovery options you may need, then weigh those needs against the listed capabilities and limits.
