conf_cache_save.sh runs first on array stop — snapshots partner confs from RAM cache to /boot/config/varaverk/conf_bak/ before anything else shuts down. conf_cache_restore.sh runs after conf_sync.sh on array start — if partner was unreachable and RAM cache is incomplete, loads the backup into RAM then removes it. Normal reboots: backup written, fresh pull succeeds, backup deleted unused. Edge case (partner down at boot): backup fills the gap so fallback.sh has the partner vars it needs to operate correctly.

# PURPOSE
|
|
# ─────────────────────────────────────────────────────────────────────────────
|
|
# Snapshots the partner conf RAM cache to /boot/config/varaverk/conf_bak/ on
|
|
# array stop. Survives reboot. Used by conf_cache_restore.sh at next array start
|
|
# to reload partner vars into RAM when the partner is unreachable at boot time.
|
|
#
|
|
# Runs as the first step in ARRAY_STOP_SCRIPTS — while the RAM cache is fresh
|
|
# and before anything else changes. If partner is reachable at next start,
|
|
# conf_sync.sh gets a fresh copy and the backup is never used. If partner is
|
|
# down, the backup fills the gap so fallback.sh has the vars it needs.
|
|
#
|
|
# Only partner confs are saved — own conf is always on disk.
|
|
# Location is outside the git repo and outside the main plugin folder.
|
|
