ZFS question

[joe mcguckin]

I have two system running ZFS. One system (Bldg 1), with 100TB is an archive. Our folks in that building add files to that server weekly.
In another building (Bldg 2), we have the other server and folks in that building add files to that server on a daily basis.

Periodically, I’l like to copy all the ’new’ files from Bldg 2 to Bldg 1. Initially, we’d do a ZFS send and start with both servers in identical states. But they
start diverging from there. Since Bldg 1 will have files added to it independently of Bldg 2, I think that means incremental zfs send won’t work.

Can anyone think of a clever method using zfs send to copy the files added to Bldg 2 since the last copy, to Bldg 1 without overwriting the Bldg 1 files. 

Thanks,

Joe
