My current setup for local backup & replication are pretty simple; I have two local 2012 R2 Hyper-V servers with two separate direct attached storage (one for each), the first server is production, the second server is a failover/replica. Every night (24h) I have a replication job between the two servers (with 2 incremental checkpoints) and right after the daily replication job is completed, I have a backup job for the same VM/data, where the replica server/storage is also set as backup repository, where I keep a 30 days incremental backup for data retention, in the case of accidental data deletion by my users.
Yesterday, I have ordered a third server that I want to setup in a remote DR site (offsite) and where I also want to set a replication job and a backup job for data retention, exactly the same that local, but on a offsite location. This new server will simply use a large built-in storage instead of any external storage, but this doesn't really matter... the remote DR site will communicate with my local network using a hardware (physical) site-to-site VPN upstream to the DR server.
The initial (full) replication job with the new server, SO AS ,the initial (full) backup job will be performed locally before physically moving the new server to the DR site. Despite that our total data size is pretty huge (around 30 TB before compression/optimization), our daily change rate is VERY limited, only around 10 GB to 20 GB per daily cycle (after data reduction). For this reason, the internet connection between the local network and the DR site will be pretty limited; a 100/100 Mbps fiber connection. But if we need to go live on the DR site for some reason, our hosting provider can perform an immediate upgrade to a 1000/1000 Mbps connection of even more.
I have read a lot of documentation from Veeam KB, however I am not quite sure how to integrate this new backup & replication offsite destination into my local daily routine;
- Is it better to use a "backup copy" job from local backup job to the DR site or to create a separate job for backup from local to DR site?
- Is there any "replication job copy" that I can use for my DR site or replication is only available as a second separate job?
- I also read about "Replica Seeding" option for low bandwidth WAN connection, but I am not sure to understand how it work and if it will be gainful for me for my DR site?
Thank you very much for your recommandations!
