I tried to take sp 2013 web application backup
I have used following command in sp management shell
Backup-SPFarm -Directory 'E:\SePortal_Bak\se.bak' -BackupMethod full -Item 'SEU Portal - 443' -Verbose
But I'm getting an error that Directory E:.... does not exist or the sql server permissions....
Is there any alternative way to get all the web application in only one .bak file??
Please if yes then kindly tell me..
Thanks in advance
