MSDP 2 MSDP duplication
I am participating in a project where I have to free up a MSDP storage server (running on NBA 5350). Backup images which are stored on this MSDP are duplicated (optimized duplication) to other NBA, within the same NBU domain, this time 5240. Both appliances are running 5.3.0.1 SP1 MR2, and have the same patch installed: NBAPP_EEB_ET4145974-5.3.0.1-6.x86_64. After initially seeding this target appliance 5240 with few days of backups, I cut over the backups directed to 5350 and repointed these to 5240 - played around with the SLPs. The problem that was faced is that source MSDP on 5350 was occupied ca. 120 TB. Now after a week after backups are cut off and not having all backup images being duplicated to target 5240 MSDP, that target pool is occupied in 174 TB. We are running out of disk space on target MSDP, no one knows why we see such an increase in the disk occupancy. IMHO target MSDP should not occupy more than - let's say - 130 TB. Do you have any idea as to why we see such discrepancy from our anticipation and real world?
