Which backup directory to backup?

[moniker]

In /opt/zimbra/backup I have:

drwxr-xr-x 3 root root 4096 Jan 22 20:54 4.5.0_GA
-rw-r----- 1 zimbra zimbra 2149 Feb 11 00:00 acct_name_id.dat
-rw-r----- 1 zimbra zimbra 2203 Feb 11 00:00 acct_session.dat
drwxr-xr-x 27 zimbra zimbra 4096 Feb 15 10:23 ldap
drwxr-x--- 27 zimbra zimbra 4096 Feb 15 01:00 sessions
drwxr-x--- 2 zimbra zimbra 4096 Feb 15 01:00 tmp

Under /opt/zimbra/backup/4.5.0_GA/4.0.5_GA-5.2 I have:

-rw-r----- 1 zimbra zimbra 2236 Jan 21 00:00 acct_name_id.dat
-rw-r----- 1 zimbra zimbra 2203 Jan 21 00:00 acct_session.dat
drwxr-xr-x 19 zimbra zimbra 4096 Jan 22 01:00 ldap
drwxr-x--- 5 zimbra zimbra 4096 Jan 21 01:00 redologs
drwxr-x--- 19 zimbra zimbra 4096 Jan 22 01:00 sessions
drwxr-x--- 2 zimbra zimbra 4096 Jan 22 01:00 sessions_tmp
drwxr-x--- 40 zimbra zimbra 4096 Jan 8 01:00 shared_blobs

Why are things duplicated in those directores? Do I have to backup the files in /opt/zimbra/backup or /opt/zimbra/backup/4.5.0_GA/4.0.5_GA-5.2?

Everything under the 4.5.0_GA directory can be deleted, they are backups that became invalid during an upgrade. Everything else should be backed up.

Thanks a bunch!
