I tried to restore a mailbox on my 7.2NE and it would not work, I got this in the mailbox.log:
Code:
Error occurred: no such backup for account:
I checked the backup directory and it is empty:
Code:
[admin@zimbra backup]$ du -s *
4	accounts.xml
1956	sessions
966640	tmp
I tried to back up an account from cli:

Code:
[admin@zimbra backup]$ zmbackup -f -a a.user@domain.com
full-20120725.125254.165
which happens too quick to be true, and alas,
Code:
[admin@zimbra backup]zmbackupquery

After reading the fora I ended up deleting accounts.xml which only had one account listed, but that did not do the trick. The file is regenerated after every backup:
Code:
[admin@zimbra backup]$ cat accounts.xml
<?xml version="1.0" encoding="utf-8"?>

<backupMetadata xmlns="urn:zimbraBackupMeta" version="7.1">
  <allAccounts>
  </allAccounts>
</backupMetadata>
No accounts are listed there. I guess I need to rgenerate this file somehow. That version=7.1 is suspicious too, as

Code:
[admin@zimbra backup]$ zmcontrol -v
Release 7.2.0_GA_2669.RHEL5_20120410001958 CentOS5 NETWORK edition.
I really can't sleep without having my server backed up. Pleeeease someone advise.
