Emc Legato networker MMINFO usefull TIPS

Here some of use full combinations of mminfo

Generally mminfo resides in /usr/sbin in unix, c:\programfiles\legato\nsr\bin in windows .

To query a client backup info for past 120 Hours:
/usr/sbin/mminfo -avot -c axx.domain.com -t "-120 hours"

some times we can use grep effectively with networker command :
for example above command we can use in alternative way:


/usr/sbin/mminfo -avot -t "-120 hours" | grep -i axx.domain.com

To Query a client backup info with ssid , size of saveset, tape info
mminfo -q "client= axx.domain.com" -r "ssid,name,totalsize,savetime,volume" -t '60 hours ago'

HP Data Protector CRS Cell Request Service How it works

Hi

Who is the owner of backup ?

CRS (Cell Request Service ) is the owner for all backups in HP data protector. because CRS is the intiator for all backup specifications (Except Some of BAR applications )
Why we add DBA system user in backup admin group ?
Bacause this account acts as CRS for this accounts.

What happens if CRS account is changed and it is not update in Data protector user list ?
No backu will initiated :(
