In our environment we have two NetApp storages (let say st1-a, st1-b, st2-a, st2-b)
I have multiple schedules with different retention for volumes through SMVI. One is for daily and separate for weekly backups.
One schedule consists of datastores (vols) from only one controller (for example: st1-a: have 4 d1,d2,d3,d4, st1-b: have d5,d6,d7,d8).
backups : backup_daily_st1-a,
According to SMVI GUI all backups were successful and I can do a restore ( I can see datastores with correct time stamps in "restore" tab SMVI GUI).
Now, when I try to check snapshot copies in OnCommand System Manager for particular vol (which belongs to st1-a and according to schedule only once should be backed up),
I can see snapshots like:
backup_daily_st1-a_20120820222001_xxx_st1-a:d1 <---- this one I can understand
The question is why there are 3 daily backups? I would expect only one.
Why controller B from st1 was involved as well as another storage (st2-a)?
Was this vol backed up three times?
Thanks for any input!
