Richard has several platforms with different OSs, and he's having issues with maintaining contacts. He gets a lot of duplicates. Leo says that synchronization is a hard, universal problem. It guards against deleting anything, just in case. So you end up with duplicates. Leo uses Google Contacts. But even that doesn't solve the duplicates issue. But the sync is quite good. One solution that Leo recommends, that's iPhone only, is Sunshine. It can dedupe, as well as sync.
Paul is looking for a program that can manage his duplicate photos, getting rid of them. Leo says that you want software that can get into the metadata and contents of the image to determine if it's an actual duplicate or not. Easy Duplicate Finder for Windows. For the Mac, Leo uses Gemini 2. AllDupe is a favorite of the Chatroom.
Charlie bought a device from Facebook ads that backs up his pictures, but he ended up with a ton of duplicates. Is there a better option out there? Leo says that some of these de-dupers are too aggressive and deletes all copies. So before you run a de-duper, make a backup copy of your photos one more time. That way, if it does end up deleting all copies, you'll have a backup on the Mac, there's Gemini 2, which is a de-duper that eliminates multiple copies of the same photo. But there are plenty of Windows versions as well.
Ed has a 13" MacBook Pro and after moving his music over using iTunes, he now has duplicate files and they won't play anything. Leo says what you want to do is import the music and not make a copy of it. That will tell iTunes where to go to access the music. So now, Ed will need to get a dedupe app to remove the duplications. Or you can search for everything that includes "copy 1" and "copy 2" and delete them. Then reimport them without "making a copy" enabled. That will reindex iTunes, pointing to where the files live on your external drive.
Alan got a new PC and he's trying to copy all his images over to it with an external hard drive. How can he back up his images to the cloud without getting duplicates? And how can he delete extra copies of his images? Leo says that there are some good "deduplication" apps that will work. But he'll run the risk of eliminating an image that is close to another but slightly different.
Scott is expecting his hard drive to fail soon, so he's been backing up his data. He has over 12,000 photos, and he knows that some of them are duplicates. Leo says that de-duplication is tricky because he has to preserve the originals while getting rid of the extras. If he's not careful, he could get rid of an original due to a false positive. So Scott will want an app that not only looks at the file name and size but actually deep dives into the data inside it.
G. Scott wants to organize his computer backups. He's got duplicates everywhere and multiple files and versions. Leo says he used to worry about organization, but he decided it doesn't matter. He can just let go of it. He'll have multiple copies and that's a good thing. What he really wants is a definitive copy (known as the ground truth) that is off site, and the rest will be extras.
