    Question Full and Incremental Backups occuring at same time...

    Recently our Intel Xserve; OS X Server 10.4.10; 4.5.10 ZCS NE has begun performing incremental and full backups at the same time on scheduled incremental backup days. I thought I would post some information here and see if anyone has seen this and if there was anything I could do about it.

    This appears to only occur on scheduled incremental backup days, the crontab appears correct...

    # Backups
    #
    # BACKUP BEGIN
    0 1 * * 6 /opt/zimbra/bin/zmbackup -f -a all
    0 1 * * 0-5 /opt/zimbra/bin/zmbackup -i -a all
    0 0 * * * /opt/zimbra/bin/zmbackup -del 1m
    # BACKUP END
    The full backup that occurs appears to not actually occur... here are the emails that are sent to me.

    Server: ****.com

    Redo log sequence range: -1 .. ?
    Number of accounts: 0
    First off the full shouldn't run at all, but when it does on the scheduled incremental day it does nothing. It creates the backup on the drive but it's all empty. Is this just spurious information or is it something I should be worrying about?

    Thanks,
    Michael

    It appears to be a known bug:

    hmm, that bug has been resolved and is in the version we have installed.

    However, it looks like it might be related.

    It could be that Zimbra thinks there is a newly created account (each day) and keeps creating a full backup?

    I hate to burn a support incident on something like this but I guess you do what you have to. I'll decide once I return from vacation.

    While upgrading from 4.5.9 to 4.5.10 (Mac x86) this week, I noticed the same thing: full and incremental backups for just about every day. I was busy with other problems so I set this one aside. So the issue for us was in 4.5.9 and 4.5.10 hasn't been installed long enough to see if it is still there.

    I have the same problem on our server 4.5.10 NE running on Mac 10.4.11 Intel Xserve Server.

    Its the same problem as reported by mledford.

    I upgraded to 4.5.10 the first week of December 12/07, it worked fine for almost a month, this problem started the first week of this month 1/08

    I did look at Bug 20785

    This was posted in the bug

    This issue was resolved by moving /backups/* and the redo logs and restarting Zimbra.
    If I understand correctly I need to move the contents of the backups directory.
    Could someone elaborate more on what I need to move or remove in the redo logs directory.

    Thank You
    Oscar
