Hello,
I'm trying to configure backupd in rolling mode as a final setup.
Running a first backup on few users
sync_client -A -n bck -z -v -v
after a while the process die with:
cyrus/sync_client[9540]: MESSAGE received NO response:
IMAP_PROTOCOL_ERROR Protocol error
cyrus/sync_client[9540]: do_folders(): update failed:
example.com!user.utente^archivista 'Bad protocol'
cyrus/sync_client[9540]: IOERROR: do_user_main: Bad protocol for
utente.archivista@xxxxxxxxxxx to [no channel] (tst-msg03-bck.example.com)
Error from do_user(utente.archivista@xxxxxxxxxxx): bailing out!
cyrus/sync_client[9540]: Error in
do_user(utente.archivista@xxxxxxxxxxx): bailing out!
The backupd host doesn't complain:
2020-06-18T11:50:30.528584+02:00 tst-msg03-bck backupd[1308172]:
creating sql_db
/var/spool/cyr_backup/u/utente.archivista@example.com_cxlsmX.index
2020-06-18T11:56:44.971042+02:00 tst-msg03-bck backupd[1308172]: login:
tst-msg03.example.com [10.102.42.168] cyr_backup LOGIN User logged in
So I repeated the same command, but with less verbosity:
sync_client -A -n bck -z -v
and it worked well, without errors. Uhm...
Maybe, before to run the first initial backup (sync_client -A), do I
have to stop the sync_client already working in rolling mode?
http://www.cyrusimap.org/imap/reference/admin/backups.html says "Update
cyrus.conf(5) to add a sync_client(8) invocation to the SERVICES section
specifying (at least) the -r and -n channel options.". Really maybe you
intend START. In SERVICE I need to specify a listen too, this is not
very clear to me.
Around of backupd I would ask two other questions:
1) The backupd host always claims this:
backupd[1309970]: DBERROR: reading /var/lib/imap/db/skipstamp, assuming
the worst: No such file or directory
Could you tell me how to fix that DBERROR too?
2) Is there a way to delete a user from backupd host?
Thank you very much
Cheers
Marco
