（5）找到其中任意备份的ID号，可以在目录库中查看
YCZBJTBACKUP:/home/maintenance # bpimagelist -backupid ERP-DEV-SUSE11_172.18.1.22_1630184414 -U Backed UP Expires Files KB C Sched Type On Hold Policy ---------------- ---------- -------- -------- - --------------- ------- ------------ 08/29/2021 05:00 10/30/2021 397152 117865255 N Full Backup 0 VM_EPR_DEV_172.18.1.22_Monday_5
（6）执行延期操作
YCZBJTBACKUP:/home/maintenance # bpexpdate -backupid ERP-DEV-SUSE11_172.18.1.22_1630184414 -d 11/29/2021
Are you SURE you want to change ERP-DEV-SUSE11_172.18.1.22_1630184414 to expire on Mon 29 Nov 2021 12:00:00 AM CS y/n (n)? y
