[SOLVED] Yet Another Backup Script for Community Version

Postby xenonsky » Sun Feb 10, 2013 12:08 pm

[quote user="TheChief79"]Last time i had to backup and restore my Zimbra 8.0.2. For the ldap database i used the tool mdb_copy which is included in zimbra.
So maybe this is a good way:
1. rsync zimbra to backup directory and exclude ldap db (maybe --exclude=/opt/zimbra/data/ldap/mdb/db/data.mdb)

2. Stop zimbra and copy the ldap database with mdb_copy (usage: mdb_copy srcpath dstpath). This will not copy the whole sparse file, it will copy the real size file.

3. Maybe rsync again

4. Start zimbra
mdb_copy worked great for me.
To restore on a new server:
1. I installed Zimbra (same verison) with ./install.sh -s

2. Moved the new Installation with mv /opt/zimbra /opt/zimbra_new

3. Copied the backup into /opt/zimbra

4. Started Zimbra

5. Ran the installer again with ./install.sh
Works![/QUOTE]


What should be correct syntax for running mdb_copy?
I put this line into my script:

/opt/zimbra/openldap/bin/mdb_copy /opt/zimbra/data/ldap/mdb/db /opt/zimbra/ldap-backup/`date +%s`
but I keep getting the following error when running the backup script:

mdb_env_copy failed, error 2 No such file or directory

[quote user="xenonsky"]Thanks for the tips, I've just added the path to /etc/crontab and rebooted, then manually try to run a full backup and still got the same error:
Doing a hotsync of /opt/zimbra/ to /tmp/fakebackup/

rsync: writefd_unbuffered failed to write 4 bytes to socket [sender]: Broken pipe (32)

rsync: write failed on "/tmp/fakebackup/data/ldap/mdb/db/data.mdb": No space left on device (28)

rsync error: error in file IO (code 11) at receiver.c(301) [receiver=3.0.6]

rsync: connection unexpectedly closed (981 bytes received so far) [sender]

rsync error: error in rsync protocol data stream (code 12) at io.c(600) [sender=3.0.6]

rsync threw a hotsync error. this is not unusual, continuing...
any modification required for the original zmbak_v.0.8.sh script?
Thanks![/QUOTE]

It works for me running as root and as zimbra user: /opt/zimbra/openldap/bin/mdb_copy /opt/zimbra/data/ldap/mdb/db /tmp
ls -l /tmp

-rw-r--r-- 1 root root 1171456 Feb 14 10:19 data.mdb

finally changing from: /opt/zimbra/openldap/bin/mdb_copy /opt/zimbra/data/ldap/mdb/db /opt/zimbra/ldap-backup/`date +%s`
to: /opt/zimbra/openldap/bin/mdb_copy /opt/zimbra/data/ldap/mdb/db /opt/zimbra/ldap-backup
and now everything works.


When restore the data.mdb just mdb_copy the other way should work then? without having the file size bloated to 85GB again, right?

Yes, just copy back the file. On restore i didnt use mdb_copy (made just normal copy), but it also should work.
When you start your new restored zimbra, the file will grow again over 80gig. mdb_copy is just useful to make a backup without the big ldap sparse file, but with real size file.

Attached is the modified script I'm using.
Changed RSYNC option from this:

RSYNC_OPTS="-aHK --delete --exclude=*.pid"
to this:

RSYNC_OPTS="-aHK --delete --exclude=data/ldap/mdb/db/data.mdb --exclude=*.pid"
Between 1st RSYNC and 2nd Quick RSYNC I added the following two lines to remove any existing previous copy of mdb files from /opt/zimbra/ldap-backup (may have to create this folder manually and change permission like "chmod 777" on ldap-backup folder) , then do the mdb_copy, and let 2nd quick RSYNC back it up.
rm /opt/zimbra/ldap-backup/*.mdb
/opt/zimbra/openldap/bin/mdb_copy /opt/zimbra/data/ldap/mdb/db /opt/zimbra/ldap-backup
Hope this works for everyone.

It looks like the link is not valid. Anywhere else I can get the mta dummy to install manually.

I think mta-dummy is gone from newer Ubuntu. Try this:

Alternately, you could install sendmail or xmail, or postfix (which comes with its own sendmail for compatibility), but you'll need to be sure to disable any of their startup services. Lastly, you can point the default sendmail to use the one that comes with Zimbra, How to "fix" system's sendmail to use that of zimbra - Zimbra :: Wiki.http://www.zimbra.com/forums/administrators/15275-solved-yet-another-backup-script-community-version-48.html#post215050">http://www.zimbra.com/forums/administrators/15275-solved-yet-another-backup-script-community-version-48.html#post215050"]
