Hi,
I have a scenario where I have a setup of one Management server and one Primary recording server with its Live Database being 4 TB and an archive storage of 90 TB SAN (calculated for 21 days). Now I have to select a fail-over recording server for the primary recording server in hot standby mode and my plan was to select one with the same configuration. (4 TB Live DB inside the server & 90 TB SAN storage for archive).
From the XProtect user guide & Milestone discussion forums, I understand that there will be no such thing as archiving possible when a failover server has taken over and that the failover will only keep the recordings either until they are merged back or until the failover recording server runs out of disk space. By the word ‘disk space’ in the previous line, I infer it is the Live Database which is 4 TB in this case. Now, when this failover server’s Live DB space is filled up and the primary recording server is still not brought back, the failover recording server will start deleting the earlier recordings FIFO basis (without archiving to the 2nd 90TB SAN) to store the new recordings. So, I’ll have loss of video data even though I have a second 90TB SAN, as the failover recording server will not do any archiving.
Question 1: Now, to avoid this loss of data, can I choose the failover recording server with 94TB storage space in it, which will serve as Live Database for it and let it keep the recordings until the primary is active again? Or is it not possible to define the failover recording server with a larger Live Database than its Primary Recording server?
If answer to Question 1 is ‘Yes’, then:
Question 2: Let’s say the failover recording has been active for up to 10 days and on the 11th day, primary recording server has been brought back, now during the merging process, will the larger Live Database failover server (that contains 10 days of recording) be seamlessly merged back in to the primary recording server’s database (which is relatively less) and then on to the archive?
My aim is to overcome the ‘no archive’ limitation in the failover recording server. Above two questions are for XProtect Expertas well as XProtect Corporate systems.
Thanks in advance.
