NetWorker：不應允許儲存集 ssretent 短於 ddrltime 鎖定時間

無法從啟用 Data Domain Retention Lock Governance （DDRLG） 的裝置移除儲存集 

在伺服器中觀察到以下錯誤 daemon.raw：

• Linux： /nsr/logs/daemon.raw
• Windows （預設）： C:\Program Files\EMC NetWorker\nsr\logs\daemon.raw
• NetWorker：如何使用 nsr_render_log 呈現.raw紀錄檔

儲存集的保留時間已變更為少於 DDRL 鎖定時間
的時間 範例： 

[root@nwserver ~]# mminfo -avot -r ssid,cloneid,name,savetime,ssretent,ssbrowse,ddrltime -q ssid=4216343
 ssid         clone id name                            date    retent   browse  ddrltime

If this save set has dependents with longer browse or retention periods, the dependent savesets will not be browsable after this saveset's browse and expiration dates.
Are you sure you want to change the browse policy expiration to `Sun Jun 28 00:00:00 2026' and the retention policy expiration to `Sun Jun 28 00:00:00 2026' for this saveset? (yes/no)  [no] yes
The browse time and the retention time for the save set name 'E:\' with save set ID '4216343'have been changed to 'Sun Jun 28 00:00:00 2026' and 'Sun Jun 28 00:00:00 2026', respectively.
