Hi
i created a weekly system backup task on task scheduler. bakcup disk C and E to disk F
the general setting like below
Method 1
in the task scheduler "edit action" , script: %windir%\System32\wbadmin.exe
in the "add arguments" start backup -backupTarget:f: -include:c:,:e: -quiet
the job actually succeed and completed according to history log. but i found nothing in Disk F, nothing generated, all this task starts and completes in just 1 second and the log shows "returns code 4294967295"
no idea where went wrong.
Method 2
then i tried to run cmd as admin, and type "wbadmin start backup -backupTarget:f: -include:c:,:e: -quiet", backup works and backup file generated in F:. but this backup method is only once bakcup, not weekly
Method 3
so i tried another way, ran cmd as admin "schtasks /create /sc weekly /d Sat /tn weeklysystembackup /rl highest /st 3:30 /tr "wbadmin start backup -backupTarget:f: -include:c:.:e: -quiet" " it looks the same result as Method 1, nothing happened.
could someone explain me why Method 2 works instead of 1 & 3? and how to make method 2 into a weekly job?
