Cbbackup shows done without completing 100%

Hi Forum,
When I am doing the cbbackup on a couchbase server, it shows done even without completing 100%.
Is this a normal behavior?
It shows as following -
PS C:\Program Files\Couchbase\Server\bin> .\cbbackup.exe http://10.2.0.109:8091 E:\CB_Backup\10.2.0.109-allocations -u A
dministrator -p xxxx --single-node -b allocations

Hi csrohit,
Thanks for using our product.
Could you tell us more about your backup issue? About Couchbase server version installed? Operating system and data size?
Thanks
