We're using Veeam Availability Suite V10 and planing an upgrade to v11 this summer.
In our 2 main DC, we've got 2 veeam servers each backing up our whole VMWare private infrastructure (still ESX 6.7).
Each servers run the same jobs spread evenly across the night (incremental + one active full each weekend).
On every morning, we run on each server a backup copy job (secondary target/SOBR) which cross-copies to an external equallogic located on the other DC (safety).
As is, the backup window last about 8 hours (6/8PM - 2/4AM) and the backup copy about the same (7AM - 3/4PM)
We plan to add a further protection, beside long term storage with newly bought tape servers and libraries (dell ML3/LTO7) but don't want to run another backup to disk which would impact our production during business hours so a few questions :
-is it possible to run a "backup to tape" job based on our backup copies ( VM -> backup -> backup copy cross DC -> backup to tape ) ?
-can the tape servers be "standalone", as long as they've access to the backup copy (ie. read only equallogic volume access) ? Our must the tape servers be the same as the VBR servers ?
thanks for your advices

best regards,
Gilles
