BakBone在索引系統(tǒng)方面的優(yōu)點– 每個文件信息在索引文件中保存空間很小僅為 64bytes– 能夠快速地找到相關信息– 無需繞帶通過索引信息直接抓取式恢復? Legato的索引系統(tǒng)– 每個文件信息在索引文件中保存空間很大有 220bytes– 找到信息非常的慢– 回繞磁帶后才能進行恢復數(shù)據(jù)? Veritas的索引系統(tǒng)– 每個文件信息在索引文件中保存空間很大有 220bytes– 找到信息非常的慢? IBM TSM的索引系統(tǒng)– TSM的索引大小大約是 BakBone索引大小的十倍– 如果文件數(shù)量很大， TSM的備份與恢復速度將會極慢Company Confidential
