Netgear EDA 500 User Manual

If Windows users access your storage
system, enable this protocol.

Used mainly by Microsoft Windows computers
and sometimes by Mac OS X computers, this
protocol is enabled by default. It is sometimes
referred to as the CIFS (Common Internet File
Service) file-sharing protocol. SMB uses TCP/IP.

SMB(Server Message
Block)

If Linux or Unix users access your stor-
age system, enable this protocol.

Linux and Unix computers use NFS. Mac OS X
users can access NFS shared folders through
console shell access. Your ReadyNAS system
supports NFS v3 over UDP and TCP and NFS
v4 over TCP.

NFS(Network File Ser-
vice)

If only Mac OS X users access your
storage system, enable this protocol.
However, in a mixed Windows and Mac
environment, NETGEAR recommends
using SMB only.

Mac OS X computers use AFP. Your ReadyNAS
system supports AFP 3.3.

AFP(Apple File Protocol)

If users access your storage system
using FTP, enable this protocol.

Many public file upload and download sites use
FTP. The ReadyNAS supports anonymous or
user access for FTP clients. You can elect to set
up port forwarding to nonstandard ports for pas-
sive FTP, allowing clients to initiate a connection
to the ReadyNAS.

FTP(File Transfer Proto-
col) and FTPS(FTP with
SSL encryption)

If users access your storage system
from a device that supports Rsync, en-
able this protocol.

Fast file-transfer protocol that uses a delta-
transfer algorithm to send only the differences
between the source file and the existing file.

Rsync

If users access your storage system
from a device with a web browser, includ-
ing a smartphone or tablet computer,
enable this protocol.

Used on the World Wide Web.

HTTP(Hypertext Trans-
fer Protocol) and
HTTPS(HTTP with SSL
encryption)

Bit rot is a term sometimes used to describe the gradual changes in disks causing a slow loss of reliability.
ReadyNAS OS can use the redundancy in RAID-protected disks to check for bit rot and rewrite corrected
data.

RAID levels other than RAID 0 provide data redundancy used to detect, and in some cases correct, disk
read errors. Sometimes a read error is a one-time error, but other times, the data on the disk is no longer
reliable because of changes to the disk with age (disk bit rot). With bit rot protection turned on, when an
error is detected, the data is rewritten, which restores the reliability of the data, in effect restarting the
clock on the bit rot.

Bit rot protection is available for any folder stored on your ReadyNAS server and is on by default.
