Best backup practices and recovering lost data.
Backup and Recovery
Alan wants to know if having a recovery partition is a good idea. Leo says it is, right up to the moment the hard drive goes bad. Leo prefers to have an image on a USB key that he can blast on the hard drive when he needs it.
John has a Lenovo X5 and he put a special PIN code password into his computer. Now it won't accept the code because of the special characters he used. It also won't accept his fingerprint ID. Leo says that there should be an option to recover his account with his Microsoft ID. He should go to another computer and sign onto his Microsoft account to make sure it's working and valid. He can reset it with a new login, just in case. Then he should see if the recovery option appears.
Harvey wants to know what happened to the Windows image backup utility. Leo says it's still there, but it's oddly called Windows 7 backup. Here's a few other options:
Carlin has an iMac that's about 6 years old and it's getting slower and slower. She brought it into a technician, who said it was too old to get parts for it. Leo says that's not really accurate. It's always best to take the iMac into the Apple Store when it needs repair or upgrading, and it can be upgraded.
Andrew misses FDisk in MSDOS. He liked typing from the command line. Leo says that FDisk still exists in Windows, and when he deletes a partition with it, the data isn't lost, it just loses the structure of partition information. If he wants to erase all the data, Leo recommends Darik's Boot and Nuke (DBAN). It erases the data, overwrites the hard drive, erases it and overwrites it again. Seven times. So there's no way the data can be recovered.
Paula was trying to backup her desktop with Carbonite, and now she's finding that Dell and Microsoft OneDrive are overlaying their own versions of backup, fighting for her attention. How can she disable those? Leo says she can disable Dell Backup in the system tray. That's pretty simple. But it will probably restart when she turns the computer back on. So she'll have to remove it from the startup options. Leo says having both local and off site backup is a wise idea. She'll want three copies of everything at all times. As for OneDrive, it's very good, but she'll have to pay for it.
Tim uses Time Machine for his backup, but the backup fails intermittently. His Synology NAS is citing improper credentials as the cause. Leo says that encryption certificates need to be renewed from time to time, and if he's encrypting his data on backup, that could be the issue.
There is a post on Synology forums about this: Time Machine, Making it Work. Learn from my Suffering. There are some steps that can help.
Paul had a Dell XPS computer, then he got an iMac running Boot Camp. He hasn't been backing up since December. He changed the file structure when he moved to the new computer, and now his backups are duplicates instead of a select backup folder. Leo says he can tell his operating system where his home folder is in the partition. Once he's done that, he can delete the duplicates.
Dana wants to know if he should reformat his iMac hard drive to make it run faster. Leo says often that's the best thing to do. Since Dave has a bootable image from Super Duper, he can do it and be back up in minutes. He should just boot from the image, then copy the image to his hard drive and he'll be back up. Sometimes it just takes a little spring cleaning. Better yet — he can get an SSD and use the hard drive as his data drive. His computer will be a lot faster with that.
