e2fsck is used to check the ext2/ext3/ext4 family of file systems. For ext3 and ext4 filesystems that use a journal, if the system has been shut down uncleanly without any errors, normally, after replaying the committed transactions in the journal, the file system should be marked as clean.

It protects your data and syncs your data from your devices so you have a copy. NAS devices often have redundancy and allows for a second copy of your data to be made in case a hard disk fails – something that does not happen with single drive external hard drives. A disaster-proof NAS is even better.
NAS devices aren't necessarily cheap. A NAS that deals with a lot of multimedia files will cost you at least $500, and that does not include the size of the hard drives, which can cost anywhere from $50-$200.
The Benefits of NAS DevicesPart of the point of having a NAS device that's always on is that you can access it from wherever you have an internet connection.
The home network does not need internet to work internally. No access from the internet will be possible. This includes phones not connected to the internal WiFi. NAS means Network Attached Storage, which means, that the device is, in it's essence, a small computer with a connected hard drive.
