If the backup device is heavily striped , such that the maximum write speed to the backup device greatly exceeds the speed at which it can append data to a file , then it can be appropriate to place several logical backup devices on the same stripe set 如果將備份設(shè)備高度條帶化,以便使對備份設(shè)備的最大寫入速度遠遠超過備份設(shè)備將數(shù)據(jù)追加到文件的速度,則在相同的條帶集上放置幾個邏輯備份設(shè)備會比較合適。
