# Denni obnova zrcadla Medicus DB z nejnovejsi gbak zalohy do Firebird kontejneru
|
|
# + GFS retence zaloh.
|
|
#
|
|
# Zalohy se v adresari HROMADI a nejnovejsi se muze prave PRENASET pres rsync. Proto:
|
|
# - vybira nejnovejsi MEDICUS_*.zip podle nazvu (RRMMDD_HHMM -> lexikalne = chronologicky)
|
|
# - pamatuje si posledni uspesne restorovanou (last_restored.txt) -> neni-li nic novejsiho, konci
|
|
# - ceka, az velikost prestane rust (probiha-li rsync), a overi integritu (unzip -t),
|
|
# teprve pak restoruje -> nikdy nezpracuje nekompletni prenos
|
|
# - marker se zapise az PO uspesnem restoru
|
|
# - na konci spusti GFS retenci zaloh (prune_backups.sh)
