Sorry if this topic has been addressed previously. I did a search and found several threads about backing up in general but nothing specific to software.
The purpose of the thread is to help me understand my current software or solicit recommendations for a different program.
As a bit of background, I currently have a 3TB external hard drive that stays connected to my desktop computer. The desktop has two drives, a 500MB SSD(C:\) and a 1TB conventional HD(J:\). All of my photos reside on the conventional HD. Currently they fill about 450GB or just under half of the drive space. I've been using the Seagate software that came with the external drive and have it set up to backup only the photo files weekly. I also store about 350GB of specific files directly to the external drive with no copies on the desktop. So in other words about 800GB of content without any duplication.
Now here's the problem. I keep running out of space on the external HD. When I look at what's on the drive, the weekly backup files range anywhere from a couple of GB up to the full size of the folder that holds my photos. My understanding was that the backup software should only make copies of files/folders that have been changed since the most recent backup date. But that's not what appears to be happening. I haven't been able to nail down why it sometimes copies the entire master folder and sometimes only a few files.
Does anyone else use the Seagate software successfully?
What other programs do folks use?
This is more of an annoyance than a critical issue for me. In addition to the connected backup drive I simply use windows once a month or so to copy to yet another external HD. I have two of them and alternate between them. The intent of using the backup software was that it would go way back in history so if I somehow accidentally deleted some files and didn't discover my mistake for a while, the backups would still be there.
