Best backup practices and recovering lost data.
Backup and Recovery
Steve's data center got attacked by ransomware. Fortunately, they had two locations and was able to shut one down, clean it, and then reinstall with only 3 hours of downtime. Leo says that's fantastic. But a hot backup can let the ransomware spread to your backup. So the key is to keep the second network only connected every three hours. That will give time to take down the infected network before the next sync connection time.
Micah is getting an error message every night after backing up with iDrive (a sponsor of The Tech Guy radio show) that says that five files have failed. What gives? Leo says to look in the View Logs option by ctrl-clicking on the icon. It could be a permissions issue for that file, or a file you don't want to be backed up anyway. So look to see what files are failing in the View Logs. Odds are, it's a permissions issue.
Kyle has a home theater PC loaded with media and backups on ten different hard drives that he swaps out. Leo calls that a JBOD (just a bunch of discs). But Kyle is having an issue with the drives getting errors while erasing and starting a new backup. Leo says that the flaw could also be in the backups themselves. It also changed to MBR (master boot record) and cut the drive storage in half. He also can't reformat it with GUID using Windows 10. Is there a special utility he can use? Leo says there is an MBR to GUID command in Windows.
Michael says the time has come to let go of his Apple Airport and update to a new router. Leo says new mesh technologies do a better job and Apple hasn't kept the Airport design up to date. But Michael uses Time Machine to back up his Mac. Do any of the mesh systems offer USB support? Leo suggests going with Network Attached Storage or NAS and backup that way. That will work with any router. Leo prefers Synology, and you'll also need to buy the hard drives to put into them. A good two drive model would work great, and it supports Time Machine. It also backs up to the cloud.
John wants to know if he needs iDrive anymore when he also has Microsoft One Drive. Leo says that the problem with One Drive is that it only syncs whatever you put in the dedicated folder. iDrive, by contrast, backs up everything and has versioning, or multiple versions of the same file. DropBox is starting to do that as well. iDrive also has a snapshot feature, which will take a snapshot of your drive that you can restore to should your drive get compromised.
Gustavo has a 20-year-old Powerbook Mac that he hasn't turned on in years. He plugged in an external hard drive, and somehow the Powerbook now views the hard drive as empty. Can he recover it? Leo suspects that the age of the drive caused the drive to fail. Or the cable may have failed. Or even the external box itself. Leo recommends taking it out and connecting it to a more modern computer.
Scott is having issues with his Synology NAS. He can't access it remotely. Leo says it sounds like a settings issue and he recommends going into the router settings and see if the router can see it. Then reserve the DNS number that's listed for that Synology. If it doesn't, there could be a problem with your router or with a power surge that fried your board. But that's unlikely.
Jerry is a photographer and wants to know more about backing up his photos. Leo says it's best to adopt a 3-2-1 backup strategy. Three backups, two different formats, one off-site or in the cloud. Check out DPBestflow.org for details.
Michael changed his laptop to a 2TB hard drive, but as he tries to move his data over to the old drive, it can't be read. Leo says the best way is to get a $35 USB dongle that turns your old hard drive into a USB external drive. But Michael says that he gets a message requiring it to format. Leo says the drive may have corrupted and died. He recommends trying to use Recuva to recover the lost data, but it may be a mixed bag as to what it can recover and what it can't.
