Problem:

Following error appears when a full backup is executed :

/opt/zimbra/bin/zmbackup -f - all 
Error occurred: invalid request: Missing account list. 

Following error is observed in /opt/zimbra/log/mailbox.log file :

Error occurred: invalid request: Missing account list

Solution

This issue is seen when the /opt/zimbra/backup/accounts.xml file is missing or corrupt, it makes the new backup unable to read the previous backup entry. Move the old sessions directory and corrupt accounts.xml file to resolve this issue using the given steps :

su - zimbra 
cd /opt/zimbra/backup 
mv sessions sessions.OLD 
mv accounts.xml accounts.xml.OLD

Verify the solution by taking a full backup again -

/opt/zimbra/bin/zmbackup -f -a all

Suggestion

zmbackup is replaced by NG backup from ZCS 8.8.x onwards. The current LTS version is ZCS 8.8.15.
