В итоге я написал скрипт bash для этого. run-backup-maintenance.sh
Пример использования: run-backup-maintenance.sh d7w4m12y10 /cygdrive /d /backup ".* .Tar»
ПРИМЕЧАНИЕ. Все ежедневные резервные копии должны быть записаны в: /cygdrive /d /backup /daily
При запуске с параметром d7w4m12y10 этот скрипт гарантирует, что со временем:
/cygdrive/d/backup/daily will contain daily backups for the last 7 days
/cygdrive/d/backup/weekly will contain weekly backups for the last 4 weeks
/cygdrive/d/backup/monthly will contain monthly backups for the last 12 months
/cygdrive/d/backup/yearly will contain yearly backups for the last 10 years
Наслаждайтесь!
