fbackup备份系统的0-9个级别分别是什么意思
fbackup备份系统的0-9个级别分别是什么意思？望高手解答下。 A backup level is a level you define that identifies the different degrees of incremental backups. Each backup level has a date associated with it that indicates when the last backup at that level was created. You can have up to ten backup levels (0 through 9). For example, level 0 is a full backup; level 1 backs up files that changed since the last level 0 backup; level 2 backs up files that changed since the last level 1 backup, and so on. 查manpage
