In the past, it seemed sensible to create a separate F: partition to hold my data away from the operating system on the C: partition. The advantage was that malware is less likely to cross into the data partition. Also it becomes possible to backup and restore each partition separately. A good solution to a malware incident might be simply to restore a previous version of the operating system without touching the data partition.
I have redirected the following folders to the F: drive: desktop, documents, downloads, music, pictures, videos.
This has worked reasonably well except that some software installer programs refuse to work from the F: partition and need to be run from the C: partition.
Times have changed over the last few years and I am wondering if this is still worth the trouble. Perhaps it would be easier to keep successive backups of the entire hard drive and, when necessary, restore everything at one time.
I would welcome any thoughts on this.
