Depending on the definition of offsite, you have a fundamental problem: either invest the time/effort compressing or take extra bandwidth, which is less costly? Hopefully a delta transfer makes sense in your situation and should save far more than compression would once the original copy is offsite. ________________________________ From: CentOS <centos-bounces at centos.org> on behalf of Valeri Galtsev <galtsev at kicp.uchicago.edu> Sent: Thursday, July 2, 2020 8:02 AM To: centos at centos.org <centos at centos.org> Subject: [EXTERNAL] Re: [CentOS] [OT] Bacula offsite replication CAUTION: This email originated from outside of the organization.

Then when you restore, search for specific files will be faster. And it will help your backup volumes transfers as well.
