DeDupliaction Folder Memory Warning - 1.5GB per TB of Storage
Can someone give me an insight into the underlying reasons for the warning that Backup Exec 2010 R3 gives when a deduplication backup to disk folder is created on a large volume?
I'm absolutley bought into the fact that deduplication is horrendously CPU and Memory intensive and so recognise this is a somewhat silly question, but I kind of have a couple of peripheral questions:
If this warning is ignored how to problems manaifest themselves? Do jobs fail or just take ages to complete?
If a server has 12GB and a 20TB lun for deupe (which will cause this warning to appear) are errors\failures still possible if the size of data being backed up is only about 5TB - therefore significantly less in size than the threshold depicted in the warning message?
What if the client plans to increase the server memory in line with the data growth but wants the array to be initially sized at 20TB whilst data backups are low?
I guess a single Backup Exec server can only have a single dedupe folder? so configuring the storage is configured in 2 x Luns of 10TB with a dedupe folder on each wouldn't be an option - right?
