Deduplication ratio and Backup disk

[Home_224]

Dear All,

Our new project to use HCI backup to VM to disk and replication disk to tapes, use disk to disk to tape backup strategy.  I have to calculate the sizing of how many disks for VM backup and deduplication ratio.  I get the information , the HCI VM size is in 60 TB in total. VM backup weekly full backup and incremental backup period keep in 12 months.  May I know how many disk for data backup, deduplication ratio and tapes for this situation?  I have to give it to my boss on Monday in hk time zone. May I know where can I get this online calculation ?

Thanks,

[Nicolai]

Hi @Home_224 

Take a look at the "NetBackup™ Backup Planning and Performance Tuning Guide" - section MSDP sizing considerations

Hi @Home_224 

If  you have a good relationship with your account team/SE you may be able to ask them to help you do the calculations. They have internal tools they can use.
