Remove all folders within another folder except the lastest 1, 2 or 3.
I am using this command to remove all files and folders older than 24 hours;
Code:
find /databackup/dbs/* -maxdepth 0 -type d -mtime +0 -exec rm -rf {} \;

However, if/when backups to this folder fail and are not updated, it will completely destroy any backups we have in that folder.

What can I add to that line so it leaves the latest two folders (for example)
that were created.
So if backups don't run for a week I'm not stuck with an empty backup folder.

can someone help?

TIA

new

NEW(1)                                                               [nmh-1.5]                                                              NEW(1)

NAME

       new - report on folders with new messages

       fnext - set current folder to next folder with new messages

       fprev - set current folder to previous folder with new messages

       unseen - scan new messages in all folders with new messages

SYNOPSIS

       new [sequences] [-mode mode] [-folders foldersfile] [-version] [-help]

       fnext is equivalent to new -mode fnext

       fprev is equivalent to new -mode fprev

       unseen is equivalent to new -mode unseen

DESCRIPTION

       New  in  its  default  mode  produces  a  one-line-per-folder  listing of all folders containing messages in the listed sequences or in the
       sequences listed in the profile entry "Unseen-Sequence".  Each line contains the folder, the number of messages in the  desired  sequences,
       and the message lists from the .mh_sequences file.  For example:

            foo     11.* 40-50
            bar    380.  760-772 824-828
             total    391.

       The `*' on foo indicates that it is the current folder.  The last line shows the total number of messages in the desired sequences.

       New crawls the folder hierarchy recursively to find all folders, and prints them in lexicographic order.  Override this behavior by provid-
       ing foldersfile containing the pre-sorted list of folders new should check, one per line.

       In fnext and fprev modes, new instead changes to the next or previous matching folder, respectively.

       In unseen mode, new executes scan sequences for each matching folder.

FILES

       $HOME/.mh_profile          The user profile

PROFILE COMPONENTS

       Path:                To determine the user's nmh directory
       Current-Folder:      To find the default current folder
       Unseen-Sequence:     The name of the unseen message sequence
