I'd get a larger drive, and use Acronis or Paragon partition managers to dupe the drive onto the larger partition.
Tell me about it... I started with 250GB Hard drives in my XP system, when I Upgraded to Win 7 I had to get 320 GB drives, then 500 GB drives, and finally 1 TB drives. Right now I have 2 500 giggers, they are totally packed... Last month I bought another 1TB drive, it is totally full now. I just don't know where the space goes, I absulutely require everything I have saved, cos I build and repair computers, I have to keep an exhaustive library of
Drivers, OS's. I even run a program that allows me to read my Mac partitions as if they are attached right to my PC.
If you are not sure about what you need... And if your backup is bursting at the seams, then do this:
1) Check your system - Make sure it is in absolute perfect order, no little glitches. If that is the case then:
2) Delete your entire Backup drive. Sounds drastic, but if you are in no danger, you should be OK.
3) Once you clear ouot all that space, just make one Brand New Backup, and then tell your Backup program to make a Backup ONLY When you tell it to.
Cos it counds like you have some kind of Automatic Backup going, I'd dhut it off, do it manually, cos if you keep going, your backup partition will soon get totyally filled.
Ideally, you want to keep all of your drives about 1/4 full for best computer performance. Now myself, I keep them 80% full, causes me a lot of problems cos I'm a packrat, cant affor 6 2 TB drives to move all my storage onto, so I gotta keep all my archives on sevreral partitions.
If your system is working well and you have at least half of your system drive free - Then delete your backup drive.
But only if there is nothing on that drive that is not on your System drives... If you are saving a lot of Documents and ISO images and pictures, you may want to keep only those on a separate drive, other than your System backup drive.
