NAS maker Synology recently released the DSM 7.0.1 RC. This new version of the in-house software fixes several issues and brings improvements as well. What is particularly surprising is that this is the version of the DSM in the Release Candidate. It may still contain bugs, which Synology seems to assume because they decided to make it available to everyone. Was there an urgent need to release this version? What is this hiding? Is this a new strategy for Synology? Explanations…

Synology DSM 7.0.1-42214 (RC)

On Tuesday, August 31, Synology decided to provide the first update for DSM 7.0. The surprise comes from the fact that this is a copy filter release. This is not the final version yet and it may still contain some bugs (or even disappear overnight for no reason). Manufacturer NAS sometimes offers incomplete versions (Beta, Release Candidate…), but this is the first time it has made an RC version available to everyone, on its “stable” channel. This inevitably raises some questions… Is this the new DiskStation Manager release policy? The answer may be simpler. In fact, DSM 7.0.1 is the first version compatible with NAS for FS, SA, XS / XS + and DVA . series. The latter was not able to take advantage of DSM 7 and still exists under DSM 6.2.

new: 1 petabyte, Deduplicate and sync…

In addition to this surprise, there are several important new features in this new version:

• support for SA3200D System Configurations Migration When users migrate hard drives;
• support for inversion cache between controllers to improve data consistency on the SA3200D;
• add option” Sync uploaded folders remotely “in order to Sync shared folders ;
• support creation Storage up to 1 petabyte in Btrfs format (beta size) on XS / XS +, SA (except SA3200D) and FS series models;
• addition Duplicate data on Btrfs folders in certain models;
• support for User notification When metadata storage is insufficient.

Admittedly, that’s great news, even if it’s mainly about high-end models. We would especially appreciate the possibility of creating Storage up to 1 petabyte (petabytes) and of course access (finally) Deduplication online ! On the other hand, it is entitled only to “company” funds: FS6400, FS3600, FS3400, SA3600, SA3400, RS4021xs+, RS3621xs+, and RS3621RPxs. Note that the volume must be in Btrfs (100% SSD) and have at least 16GB of RAM.

Corrections: VPN reconnection, display, vulnerabilities…

The new version of DSM 7.0.1 also brings several fixes:

• Can’t DSM Automatically reconnect to VPN after the break
