My BackupPC folder is about 190GB (backs up my home from the other drive,

a 256GB SSD. A little bigger would be awesome but not in the budget.

I would argue for putting your backups on an external drive for three reasons. First, they're cheap and being your backup, performance is not such a big issue. I use a Western Digital 2TB My Passport for this (with a Mac, but that is irrelevant); it is cheap, big (lots of backup history) and importantly: bus powered USB. So it is just the drive and a short USB cable.

Second, using an external drive avoids making painful decisions about how big your internal drives are: they need to be big enough for your data, not for your unbounded backup history.

Third, an external drive can be _removed_. Here we live in fear of the day that the disaster that takes out the real data also corrupts the backup data. Having the drive physically offline in a drawer avoids this risk. It does require you to have the discipline to remember to plug it in and do a backup regularly.

Even if you do run internal backups (eg daily or whatever to a much smaller internal partition), do some external ones too.

Finally, I also recommend an SSD for your system drive. For /var, not so important, but the OS it is fantastic.
