Hope we’re not confusing Tom, and his original question ..
But it all depends on how much personal Data you intend to collect and store in your Operating system …
And how big your Acronis backups are … or may grow to be.
Being a Pack Rat .. I’ve evolved to a system where I store my Data separately ... in another Partition.
And also carry a fresh install of Windows in a second HD which also has a backup partition of my Data.
My Data is backed up via Copy n Paste … as I collect or create it … to another Partition or my Externals.
My E: partition is my original Fresh install .. Booted to and updated occasionally.
I may occasionally make a Backup of my working drive C: .. If I think I’m headed somewhere dangerous.
But it’s my E: Partition that I depend on …
and I make Full Acronis backups of it as I may update it or recover from it … (and finish updating it)
This way .. Every recovery is a fresh install and I keep the Full Acronis Backups of
the original creation .. and about the last three versions of it.
I rarely have to worry about replacing/recovering my Data.
My OS partitions stay really small .. without any Data in them ..
which is a big advantage when it comes to recovery, maintenance or Acronis backup storage.
It’s been well worth the cost of an extra Hard Drive … and Acronis.
