Dirvish has exclude lists; it is safer to specify which drives to backup or not backup in the config file, rather than add complicated extra code to figure out which drive(s) or partition(s) to exclude. I make daily incrementals to one machine, weekly incrementals to another, and make an occasional backup drive copy for a safety deposit box at my bank. Except not lately, during COVID I avoid the bank, and all other airspaces that may contain shouting maskless morons. Note for anyone using VERY LARGE hard drives for dirvish in this way: format the drive with a shit-ton of extra inodes, or you will use those up long before you run out of data sectors. Perhaps there are file system types that can reconfigure data space into extra inodes, and also reconfigure around emerging patches of failed disk; this would be handy to fill a large backup drive chock full. Second note: Solid state drives seem attractive for backups, but they haven't been around long enough for all the very-long-term failure modes to be discovered. Using both magnetic and solid-state backup media may be safest for the wealthy and ultra-paranoid. Third note: I liked dirvish so much that I hosted it for more than a decade. Last year, I completed arrangements for a new SABDFL in New Zealand. Backup your backup software in a different hemisphere, in a nation that takes pandemics seriously.
