networker合并备份的问题

各位,请问有没有人遇到过合并备份(Consolidate)的时候,也没有报错,最后任务的状态就变成Interrupted的情况,查看日志的话也没有看出来什么,组信息里面也没有报错。

Re: networker合并备份的问题

Admin Guide中写了:

These are some of the limitations that can cause the save set consolidation process to fail:

Save sets cannot be consolidated when either the full or Level 1 save set contains a file larger than 2 GB.

Raw disk file partitions are not eligible for consolidation.

Database systems cannot be consolidated.

Renamed and deleted directories cannot be consolidated. If incremental data contains renamed or deleted directories, the save set consolidation process will detect it and abort.

LZ是给文件系统做consolidate backup还是给数据库做?以前有做成功过吗?最好能贴点截图来看看你说的interrupted状态。日志中怎么说的呢?consolidation backup成功完成?

Re: networker合并备份的问题

是给文件系统做consolidate 好像consolidate这个没成功过 全备份和增量都是成功的 忘了截图了 就是出了interrupted的那个图标,黄色的小球 日志我上传了case是51989436 日志说也是被中断了 没有成功

可见,与上面最后一条limitation是吻合的:Renamed and deleted directories cannot be consolidated. If incremental data contains renamed or deleted directories, the save set consolidation process will detect it and abort.

应该是上次全备份以后,对FSGUN01MV这个clientD:\GROUP$D:\USERS以及mail这个client/mail_archive目录做过Renamedelete操作了,所以无法对此三个save set进行consolidate backup

建议你先重新进行一次完全备份,然后以后再进行consolidate backup的话,应该就可以了。

Re: networker合并备份的问题

谢谢 请问是对D:\GROUP$ 和D:\USERS 以及mail这个的/mail_archive目录肯定没做过rename和delete,还是说对他们的子目录做这些操作也会造成这个问题呢?

Re: networker合并备份的问题

这个倒没有测试过。不过我觉得子目录修改或删除的话应该会出这个问题的。以后如果还出现consolidate backup问题的话,建议你手动做一次full backup。

Re: networker合并备份的问题

这个我比较困难 因为这个全备份数据量很大 ,而且要复制到异地做灾备,主要是复制的带宽不够,所以设定的策略是这样,第一次做全备份,然后每天做增量,一个月做一个consolidate.

在请问一下,这个consolidate是把上次全备份到今天之前的所有增量数据做一个合并吗,会合并原来的全备份吗,合并后会多大会和全备份一样大吗?如果合并失败会有影响吗

Re: networker合并备份的问题

Q:这个consolidate是把上次全备份到今天之前的所有增量数据做一个合并吗?

A:consolidate是把上次全备份到今天之前的所有增量数据做一个备份,其实就是增量之和。

Q:会合并原来的全备份吗?

A:把这个增量之和再与原来的全备份合并,变成一个新的备份。

Q:合并后会多大会和全备份一样大吗?

A:有可能

Q:如果合并失败会有影响吗?

A:没有影响,毕竟你原来备份的数据都已经备份好了。只不过对恢复的性能有改善,因为恢复的时候,只需要一次性恢复这个consolidated备份就可以了。

纠正一下:

A:consolidate是把上次全备份到今天之前的所有增量数据做一个备份,其实就是增量之和。

consolidate其实是先做一次level 1备份,然后将该level 1备份与上一次完全备份合并。和增量备份没有关系。

Q:会合并原来的全备份吗?

A:把这个增量之和再与原来的全备份合并,变成一个新的备份。

会合并,但不是将上次的完全备份和之后的所有增量备份做合并,而是先做一次level 1备份,然后将该level 1备份与上一次完全备份合并。level 1备份和增量备份没有关系。

Q:合并后会多大会和全备份一样大吗?

A:有可能

差不多。

Q:如果合并失败会有影响吗?

A:没有影响,毕竟你原来备份的数据都已经备份好了。只不过对恢复的性能有改善,因为恢复的时候,只需要一次性恢复这个consolidated备份就可以了。

相比较一个完全备份和多个增量备份而言,恢复要快。
