thanks Jim,
It works almots fine ;
find /backupMWS1 /backupMWS2 -mtime -1 -name 'ems.cmp.*' -exec ls -tc {} \;
produces:
/backupMWS1/ems.cmp.Feb01_07
/backupMWS1/ems.cmp.Feb01_11
/backupMWS1/ems.cmp.Feb01_15
/backupMWS1/ems.cmp.Feb01_19
/backupMWS1/ems.cmp.Jan31_19
/backupMWS2/ems.cmp.Feb01_09
/backupMWS2/ems.cmp.Feb01_13
/backupMWS2/ems.cmp.Feb01_17
/backupMWS2/ems.cmp.Feb01_21
/backupMWS2/ems.cmp.Jan31_21
As you can see (format name is MMMDD_HH) the files are primary sorted by folder name and then by date, if I add a |tail -1 I'm not sure to get the latest.
@Methyl :
We are using solaris 9 and ksh, about the file format i dont know, I assume it is the standart format. Backups are performed by embeded sql dumps operation in shells scripts.
dumps of main server are done every 2 hours on 2 differents disks and I must insert a crontab entry at 6AM to get the latest dumpfile and load it on a test server. This is a cheap replication procedure for developpers.

amdump
AMDUMP(8) System Manager's Manual AMDUMP(8)
NAME
amdump - back up all disks in an Amanda configuration
SYNOPSIS
amdump config [ host [ disk ]* ]*
DESCRIPTION
Amdump switches to the appropriate Amanda configuration directory, e.g. /etc/amanda/config, then attempts to back up every disk specified
by the amanda.conf file. Amdump is normally run by cron.
You can specify many host/disk expression, only disks that match an expression will be dumped. All disk are dumped if no expression are
given.
If file /etc/amanda/config/hold exists, amdump will wait until it is removed before starting the backups. This allows scheduled backups to
be delayed when circumstances warrant, for example, if the tape device is being used for some other purpose. While waiting, amdump checks
for the hold file every minute.
See the amanda(8) man page for more details about Amanda.
EXAMPLE
Here is a typical crontab entry. It runs amdump every weeknight at 1 a.m. as user bin:
0 1 * * 1-5 bin /usr/sbin/amdump DailySet1
Please see the crontab(5) or crontab(1) manual page for the correct crontab format for your system.
MESSAGES
amdump: waiting for hold file to be removed
The "hold" file exists and amdump is waiting for it to be removed before starting backups.
amdump: amdump or amflush is already running, or you must run amcleanup
Amdump detected another amdump or amflush running, or the remains of a previous incomplete amdump or amflush run. This run is ter-
minated. If the problem is caused by the remains of a previous run, you must execute amcleanup(8) and then rerun amdump.
