When doing a filesystem backup of an moderate sdbox mailstore (300GB)

Like *.log or *.backup? Or are they all "vital" for recovery?
I'm already excluding the sdbox/virtual folders as it looks like they
get created and updated as needed.
Hi, can you provide 'doveconf -n'. sdbox/virtual folders are not part of
sdbox mail format. In general, if you want to avoid data loss, you can
only omit dovecot.index.cache files, but omitting these can come with
high impact when they are regenerated. Omitting dovecot.index.log or
dovecot.index will cause loss of flags.

I have virtual folders enabled & defined.
What does "high impact" mean? A few seconds to a few minutes on
initial mailbox opening for regeneration? I can live with that as
this is for emergency backup/restore purposes.
It means there will be nothing cached, it depends on your users and what
they do. If they only open first 20 mails it will not be that bad.
Ok...so I'm *probably* ok excluding cache files then...
mmap_disable = yes
If you are not using NFS, don't disable mmap.
I'm using NFS. Mail server is running in VirtualBox guest, mounting the
host's native storage via NFS.
mailbox virtual/Flagged {
comment = All my flagged messages
special_use = \Flagged
}
You can't "alias" folders like this.
Maybe not...but it works <grin>.
namespace virtual {
list = children
location = virtual:/var/mail/%d/%n/sdbox/virtual
prefix = virtual/
separator = /
subscriptions = no
}
You should really not put the virtual indexes inside sdbox directory,
this can confuse sdbox. You should put this under
/var/mail/%d/%n/virtual instead.
I haven't had any errors show up...but if it's incorrect then I'll try
changing it.
