While this strain is mostly confined to off hours (for US and Mexico members), it often continues for some servers past 10 or 11 am America/New_York time, thus contributing to the disk i/o strain during our peak time. 31 31 32 The problem is that we run ''both'' an onsite rdiff-backup with 10 days of increments saved followed immediately by an rsync off-site backup.
