B2 tiene el mismo fallo que la papelera de MEGA con otro nombre: al borrar/espejar no elimina, oculta la version vieja y la sigue facturando. Las versiones ocultas llegaron al ~88% del tramo gratis de 10GB el 2026-07-25 (8.78 GiB facturados vs 1.75 GiB visibles). - --b2-hard-delete en el sync de crown-jewels y en el delete de reddit-intel - mega-quota-exporter ahora tambien exporta b2_visible/billed/hidden_bytes Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

# Exporter de la cuota de los dos offsites: MEGA y B2.
|
|
#
|
|
# Contexto: el 2026-07-25 la papelera de MEGA (que cuenta cuota) llenó los 20GB
|
|
# de la cuenta y tumbó rclone-mega-backup y reddit-intel-backup con "Request
|
|
# over quota". El aviso llegó del síntoma (jobs fallidos), no de la causa, que
|
|
# llevaba meses engordando en silencio. Esto expone la cuota a Prometheus para
|
|
# poder alertar con días de margen.
|
|
#
|
|
# mega_trash_bytes = usado - visible: es la métrica que habría cazado aquello.
|
|
# Con --mega-hard-delete en las rotaciones debería quedarse cerca de 0; si
|
|
# vuelve a crecer, es que algún borrado se está yendo a la papelera otra vez.
|
|
#
|
|
# B2 tiene el MISMO fallo con otro nombre: al borrar/espejar no elimina, OCULTA
|
|
# la versión vieja y la sigue facturando. El mismo día las versiones ocultas de
|
|
# B2 estaban al ~88% del tramo gratis de 10GB. b2_hidden_bytes = todas las
|
|
# versiones - visible: con --b2-hard-delete en los scripts debería quedar en ~0.
