Backup cisco Router/Switch with tacacs+ through another cisco switch

HI

i am samuel,

recently we a problem about backuping our device.

we are using cisco router(1900 series、800 series and 4000series)、cisco switch(29series and 9200series),we are using a cisco switch (29series) as a jump server to connect our router and switch

with tacacs+

the backup process wouldnt be correct while using cattools,it keep backuping the jump server but not our router and switch 。

can this problem be solved? 

THX
