# lets say you are backing up to external media like a usb hardisk drive. once in a while, you should restore the backup to an alternate location and verify and validate the restorability and fidelity of the backup.
# Following a mass file restore from backup to alternate location, perform comparison with original to confirm the backup is good and restorable

#On test restore host:
# zpool create -f tank /dev/sdb
# zpool list
mount /dev/sdc1 /mnt/bup/  #where sdc1 is the device for the external usb hdd you just plugged in
ls /mnt/bup
ls /mnt/bup/originhostname/
ls -lFh /mnt/bup/originhostname/originhostname.garage.zfs

## Thought: what belongs in here versus .profile as an alias/function? 
## Probably anything that you aren't going to call often enough to warrant spending neurons on memroizing even the alias/func name.
## in which case most of what follows should actually go elsewhere.

#Kind of an automatic listing of the services created by the running docker containers
#Like Apache Fancy AutoIndex, but for docker services that have mapped all the way out to host port.
#todo: 
# - expand well known services handling / alternative urls
# - loop to automatically refresh
# - error handling
# - pseudo clever service probing to see if we can figure out more about what is actually served up. 
#     If actually http, then maybe even traverse HTML for title tags and meta decription tags?
# - automatic publishing copy to /var/www/html if it exists?

Though it is ever shifting sands, there seems to be a sort of semi-coalescing within the Azure/Power/Fabric space. It is useful for me to pretend so, at least. Here are a handful of Tips and Techniques that I have found indispensible. Sometimes I'm kind of surprised they aren't built-in. Mostly this was accumulated from a PowerAutomate-into-* point of view, but probably will expand over time.
