How to put users’ homes on shared folders Server! version: 4.0.5+

Some of our Server! users prefer to store their users’ home folders (actually VFSs as of version 4.0) on a different machine via shared folders. For example, instead of having your user’s home point to C:\SFTPData\MyUser you want to have it point to \\\SFTPData\MyUser.

This is a perfectly reasonable and fairly common request. As of version 4.0, Server! provides a variety of methods to accomplish this goal.

The first step is always the same: creating a VFS that points to the network-shared folder, like this:


Once the VFS is created, you can proceed and create a User profile that uses the newly created VFS as its “home”. And this is where you have many options.

For example, if your entire infrastructure runs on Windows (including the machine that shares the folder) and all your systems are ActiveDirectory-aware, then you can specify the user type as “Active Directory” and impersonate the home VFS as “this user”: Continue reading

How to protect your backups from ransomware (Cryptolocker, WannaCry, and the like…) Server! version: 4.0.0+

Ransomware is a type of malware that restricts access to the infected computer system, and demands that the user pay a ransom to the malware operators to remove the restriction. Probably the most famous ransomware is Cryptolocker, and it’s definitely something you don’t want to deal with.

Regardless of the strenuous efforts put in place by Antivirus developers, the rate of infection is appalling. And what is worse is that such ransomware can also access all the shared folders on your NAS/SAN, so if you backup to a network drive your backups will be compromised too. The ransomware objectives include, in fact, preventing you from being able to restore your old (healthy) data from a backup.

Managing such situation with permissions and ACL (access-control lists) is a nightmare, and it’s hard to reach a true WORM (write once read many) situation which is the only truly secure way to prevent the ransomware from modifying the backups you’ve already stored. And if you have healthy backups the ransomware is “de facto” already defeated.

So what can you do to store your backups somewhere else in a truly WORM way? Continue reading Server! v4: the Virtual File System (VFS) Server! version: 4.0.0+

One of the biggest additions to the upcoming version 4.0 of Server! is the VFS (Virtual File System) support. But what is it exactly? And what advantages does it bring to our users?

Let’s start by setting the bar with v3. Our version 3.x, in fact – as nearly every competitor – allows you to place users’ “homes” (root directories) on a disk. It can be a local or a network disk, but it’s basically disk-based. The following picture explains the concept in a visual way: Continue reading
