David works with about ten other people in a small company, and they all share files using DropBox. They're getting conflicts, however with certain database files that they have stored on DropBox. Leo says if he has two programs accessing the same file at once, they will have problems. David wants to set up a VPN, and he was able to configure Hamachi. Leo says this won't fix the fundamental problem, though — it has to support record locking. David says that Microsoft Access supports locking, but it doesn't work with DropBox because people are accessing the file on their local systems.
network attached storage
Bruce has a network attached storage (NAS) drive and he's getting an error message. He's worried he's lost the data. Leo says that if the network RAID was set to RAID 0 or "scary RAID" then there's a chance that's the case. But if it was set as "redundant" then if one drive has gone bad, replacing it will fix it. The error message Bruce is getting indicates the entire Western Digital NAS has been corrupted and the only thing he can do is reboot the NAS and see if it self-corrects. Bruce also said that the error occurred with all the drives taken out of the machine.
Brian wants to know how safe online encryption is. Leo says that as long as he has the only encryption key, he's safe. But if he doesn't even trust that, then Leo suggests using his own Network Attached Storage. Leo uses Synology, and he syncs it to all his computers using the web.
Keith has two NAS drives attached to his network and none of his Windows-based computers can see the shared data folders, but his Android devices can. Leo says that since Keith's Chromebook and Android devices are based on Linux, it can probably see it without any emulation or extra drivers. The NAS could have a non-standard file sharing protocol that won't allow Windows to see it because it can't understand it.
Eric is looking to get a new NAS and wants to know whether he should get a Drobo or Synology? He wants everything on RAID that can be swappable. Leo says that Drobo is USB and is essentially a very large, fast USB external drive system. But for network attached storage, Leo prefers Synology. It's a computer with massive storage on his network.So it really comes down to what he'll want to use it for.
Edwee wants to create a server using Raspberry Pi. Leo says that the Raspberry Pi is very cheap at $35, but it can do a lot of great things. It uses Raspian OS, which is like Linux. There are some network attached storage operating systems that the Raspberry Pi can run, including NextCloud and OwnCloud.
Dave bought a five drive Synology NAS. He was having trouble with parity checking and so he had to go turn off services in order to get through it all. He should also use the Synology Connection System, which is a lot easier.
Angelo bought a Toshiba Laptop with Office 365 and One Drive backup in 2013. When he started to back it up to the cloud, he bought a second computer and now he's lost a lot of data because files were removed when syncing to the secondary computer. So it's deleting files off his original computer. Microsoft doesn't know what to do about it. Leo says that's a good reason to have more than one backup. One Drive is not a backup. It's a file sync system that matches two folders, or two hard drives to make them equal. That means syncing deletes as well as copying files.
Bob wants to buy a Synology NAS and discovered that it doesn't come with hard drives. Leo says that's correct. That way he can put in the right hard drive for his needs. If he's going to stream a lot of video, he'll want a faster hard drive. It isn't a cheap NAS.
Dave wants to know if his old RAID hard drives can be read by his computer. Leo says it depends. If mirrored, maybe. They're identical. But maybe not. He shouldn't make any assumptions. Dave should copy the data off it and then he can take each of them and put them in their own enclosed drives, or use a new array like Synology. Synology also does a disk check periodically to keep it healthy. When he puts them in, they'll check the hard drives as they are building the raid.
