20G，有点大啊，几个G的我到是见过

Answer 3

是你的policy, schedule多，而且保留时间长吧？

影响catalog大小的因素包括这几方面：

• 要备份的文件数
• 完全备份和增量式备份的频率
• 用户备份和存档的数量
• 备份的保留期限
• 文件全路径的平均长度
• 文件信息（如所有者权限）
• 在任何给定时刻错误日志信息的平均数量
• 是否已启用数据库压缩选项。
• 没有做过catalog 备份的；

    请教斑竹，影响catalog备份的时间的原因 ，除了上述的都有可能外 还有什么？  现在NBU656的catalog的备份时间大概有四五天了：
   下面是两个一直处于active的catalog backup的信息:
一、
2012-1-16 16:08:43 - Info bpdbm(pid=4356) staging relational database files for catalog backup      
2012-1-16 16:08:43 - Info bpdbm(pid=4356) staging NBDB backup to D:\veritas\NetBackupDB\staging        
2012-1-16 16:08:48 - Info bpdbm(pid=4356) done staging NBDB backup to D:\veritas\NetBackupDB\staging      

二、
2012-1-16 16:08:43 - requesting resource nbu_master_nh.NBU_CATALOG.MAXJOBS
2012-1-16 16:08:43 - granted resource nbu_master_nh.NBU_CATALOG.MAXJOBS
2012-1-16 16:08:43 - estimated 211965 Kbytes needed
2012-1-16 16:08:43 - begin Parent Job
2012-1-16 16:08:43 - begin Catalog Backup, Start Notify Script
2012-1-16 16:08:43 - started process RUNCMD (1620)
2012-1-16 16:08:43 - ended process 0 (1620)
Status 0
2012-1-16 16:08:43 - end Catalog Backup, Start Notify Script; elapsed time: 00:00:00
2012-1-16 16:08:43 - begin Catalog Backup, DBM Query
肯定有什么异常了。观察了下正常的catalog backup.数据量只有150M，应该不是数据量太大造成的。

    这个是运用NBCC得到的信息：
nbcc-info

1.2  Building hostname services information

Results from configured host services checks

Evaluate the space available and the potential space requirements
