The replication as it is designed means that you create an additional

instance, so when you ne
One alternative, if you are running VMs (such as VMWare or Hyper-V) is resort
to a VM backup program that will uses native change tracking (VMWare CBT and
Hyper-V RCT). This allows for a consistent and incremental backup of the VM’s.
It’s quite fast and saves lots of space. The backup is increm
Cyrus does have an integrated backup system (see
https://cyrusimap.org/imap/reference/admin/backups.html) which I'm not
sure has been mentioned in this thread. But you still have to have
enough space to keep the compressed backups on disk in order to move
them to tape or whatever archival storage
Jason,
What you mention is highly related to the replication backup we were
talking about in the previous mails. The idea is the same, they
replicate from master. Then, in a pure replica solution, the replica is
stopped, a copy of its files (in the native format) is made and it's
started agai

Well, sort of. It is a method that is actually focused around doing
backups. It happens to make use of the replication protocol because

A replica is not a replacement for a backup. You may have your specific
needs, but replica per-se mostly serves to cover for master's hardware
failures. You are no

That's the point. In the context of SME environments (Small and
Medium-sized Enterprises, i.e. from 5 to 50 employees normally, up to
250 in some countries) that we were talking about, a replication is an
overkill, IMO. But
