Looking for some feedback and answers please.
I've seen a few other older good posts about the Airgap as well but have an additional question.
As mentioned in this post (https://community.spiceworks.com/topic/ ... hem?page=3
) we like to setup a similar solution:
"Pull rather than push backup is also a way of airgapping disk based backups. If the backup appliance copies the files from the client rather than the client copying the files to it, then the backup appliance need not expose any writable shares to the LAN. "
We have a VEEAM backup server setup and an additional local "Airgap" server with lots of storage which will simply copy the latest VEEAM backup files to itself with unique local user authentication between the 2 servers. The local server will not be accessible from our main network, only from KVM console.. We like to run a scheduled copy script on the local server to only copy the most recent .VBM & .VBK files over each night. However with the reverse incremental the large VBK file will change each day.
It would be nice if we can do a block level backup somehow to only do the changes instead of the full large VBK file each time but end up with the updated .VBK.
This is not replacing our existing offsite backups, this would be in addition to add the last "1" of the 3-2-1-1 backup rule you guys are probably familiar with.
Any thoughts or suggestions would be appreciated.
