hello<br />
<br />
I have a Synology DS431j device running on DSM 4.3-3810 version. This device is part of an AD and acts primarily as a file server. Beside, it offers FTP and EMAIL services. The DSM 4.3-3810 version is rather old and the device asks for upgrade to the newest 5.0 version. My question is if anyone has performed this upgrade running these services (fileserver, ftp and email) and after upgrade was all ok. I fear that these services might get faulty after the upgrade. <br />
As a remark, I have another DS431j that servers only as backup station, for this device I have made the upgrade and all went ok.<br />
<br />
Thank you and regards,<br />
Cosmin

Computer data storage, often called storage or memory, is a technology consisting of computer components and recording media used to retain digital data. In addition to local storage devices like CD and DVD readers, hard drives and flash drives, solid state drives can hold enormous amounts of data in a very small device. Cloud services and other new forms of remote storage also add to the capacity of devices and their ability to access more data without building additional data storage into a device.

Storage

Servers are computing devices that are similar to desktop computers in that they have the same basic components, but are significantly different in size, configuration and purpose. Servers are usually accessed over a network, and many run unattended, without a computer monitor, input device, audio hardware or USB interfaces. Many servers do not have a graphical user interface (GUI), and are configured and managed remotely. Servers typically include hardware redundancy such as dual power supplies, RAID disk systems, and ECC memory, along with extensive pre-boot memory testing and verification. Critical components might be hot swappable, and to guard against overheating, servers might have more powerful fans or use water cooling.

The term "Backup" means the methods and processes involved to copy computer data (system data as well as application data) to media other than the ones where the data originally live (disk, tape, optical, cloud). "Restore" in turn means the methods and processes involved in data recovery, i. e., bringing back copied computer data to their original location. Backup/Restore primarily serves as a means of protection against data loss, be it due to disaster, corruption or sabotage. It can also be used for recovering data from an earlier point in time and even for cloning machines or applications. There is a wide variety of backup/restore software available, from expensive commercial products to free or open source tools.
