# CUTOVER final backup — valhalla R510 (run as ginnoir, right before zpool export).
|
|
#
|
|
# Takes the FINAL consistent backup of everything not already on the pool, lands it on
|
|
# /storage1 (which travels with the disks), then leaves all services STOPPED.
|
|
# Does NOT restart services and does NOT export the pool (that's a separate confirmed step).
|
|
#
|
|
# Order matters: dump DBs while their containers are still up, THEN stop everything, THEN
|
|
# tar /config (consistent), THEN stop Plex + delta-rsync it.
