Hi Friends,
In our <g class="gr_ gr_56 gr-alert gr_gramm gr_run_anim Punctuation only-ins replaceWithoutSep" data-gr-id="56" id="56">environment</g> we scheduled FULL & Diff backups weekly and daily basis respectively using SQL server agent.
but from last two days our diff backup job getting failed and gave an error message like below
Error:
NT SERVICE\SQLSERVERAGENT. Cannot perform a differential backup for database "<g class="gr_ gr_378 gr-alert gr_spell gr_run_anim ContextualSpelling ins-del multiReplace" data-gr-id="378" id="378">db</g> name", because a current database backup does not exist. Perform a full database backup by reissuing BACKUP DATABASE, omitting the WITH DIFFERENTIAL option. [SQLSTATE 42000] (Error 3035) BACKUP DATABASE is terminating abnormally. [SQLSTATE 42000] (Error 3013). The step failed.
upon checking system tables all database backed up (Full) on a daily basis at <g class="gr_ gr_1027 gr-alert gr_gramm gr_run_anim Grammar only-ins replaceWithoutSep" data-gr-id="1027" id="1027">same</g> time using below login and path.
user_Name:NT AUTHORITY\SYSTEM
physical_device_name={87101980-1AB4-4491-893F-92BB432A9F3E}4
what would be <g class="gr_ gr_1067 gr-alert gr_gramm gr_run_anim Grammar only-ins doubleReplace replaceWithoutSep" data-gr-id="1067" id="1067">reason</g> behind this ,please help me on this .
