I'm missing something here. Are you replacing the previous copy and paste backup?
Sure! I have no need to keep making more and more copies. If I need to go further back in time, I can pull out an older full backup from the backup NAS sever where I have image files going back many months (years, actually).
While that works, it does take up more room, especially if you have large amounts of data and/or want more versioning than that is likely to provide.
I only have images of my C: drive. I have Macrium Reflect set to automagically keep only the previous eight weeks. I also keep the first image of every month (I manually copy those over to another folder).
A folder/file syncing program, when set to Mirror (not the same as RAID 1) will give you essentially a clone of your data drive or partition. It compares the source and destination drives, partitions, and/or folders (depending how you set it up), then copies to or deletes from the destination as needed to make it the same as the source. You can also set it to send deleted files to a versioning drive or folder. The process is simpler, takes less time, and takes up far less space.
I agree Windows defragger (since XP) is good enough. A third party firewall is far easier for me to manage, especially for outgoing, than Windows (at least for Win 7)
What's there to manage? If you are the only user of your computer and you know what programs are installed, there's nothing to manage. For this reason, the integrated Windows Firewall works great. And because it is integrated, it goes up way early in the boot process - especially critical especially when installing Windows anew. And I am even a strong proponent of Windows Defender in W8 and W10 (MSE in W7) as a suitable anti-malware solution. That said, I also use MBAM but I believe regardless your anti-malware solution of choice, you should always have a secondary scanner just to make sure nothing sneaked by the primary.
You don't need an Abrams Tank to be safe while driving about. You just need a properly maintained basic car that is kept current, and you must drive defensively - same as must do in the tank.
Actually, it's more like comparing an F150 to a Ford Focus rather than a tank. We all have lapses in our judgment so it's nice to have an "extra pair of eyes" watching out.
I'm more concerned about monitoring and regulating outbound transmissions, such as programs unnecessarily calling home. I use ZoneAlarm's free firewall. It is much easier to mange than win 7's firewall. Once Zone Alarm has been "trained" (it takes a month or two), I see very few popups.
I switched to MSE in 2009 when W7 came out, then Windows Defender with W8 and now W10 on all my systems. And except for a few PUPs, MBAM has never found anything WD (or me) ever let past. That said, I am not "click happy" on unsolicited downloads, attachments, links and popups either. But then that does not matter which security program you use either. And for the records, the PUPs MBAM found were wanted anyway.
I've had problems with MSE so I have been using AVAST free (although it's becoming a bit bloated; I'm considering trying Panda Cloud). I also use Super AntiSpyware free and MBAM Premium (I have four lifetime licenses)
What I'm lambasting is the practice of using an internal drive for an only backup or as the only onsite backup and an external offsite backup.
I agree 100%. But that applies to external drives kept next to your computer too. A fire, flood, or thief it likely to grab that as well.
And that is why you keep them out of sight of the computer—they are less likely to be seen or even recognized as being part of the computer system. Also, it's one reason why you should have offsite backups.
