Backups and Log shipping

Does a full/differential backup made using the backup dialog box in SSMS disrupt log shiiping of that database??? if Yes how can we take a backup of that system without disrupting log shipping

Yes, it does break the backup sequence. To avoid such a scenerio you can create the backup using COPY_ONLY option. There is an excellent article in SSP for the same.

great thank u so much

i have one more question.. if we are performing differential backups after the full backup with COPY_ONLY option does the differential backup too has to be using the copy_only option???

yes

when i perform the differential backup as follows i get an error.. i cnt figure out wt is wrong.. plz help me with this
/* Full Backup Using COPY_ONLY Option*/
BACKUP DATABASE AdventureWorks
TO DISK='C:BackupAW.bak'
WITH COPY_ONLY


/* Differntial Backup Using COPY_ONLY Option */
BACKUP DATABASE AdventureWorks
TO DISK='C:BackupAW_diff.bak'
WITH DIFFERENTIAL,COPY_ONLY
error:
Processed 20576 pages for database 'AdventureWorks', file 'AdventureWorks_Data' on file 2.
Processed 1 pages for database 'AdventureWorks', file 'AdventureWorks_Log' on file 2.
BACKUP DATABASE successfully processed 20577 pages in 8.070 seconds (20.887 MB/sec).
Msg 3035, Level 16, State 1, Line 9
Cannot perform a differential backup for database "AdventureWorks", because a current database backup does not exist. Perform a full database backup by reissuing BACKUP DATABASE, omitting the WITH DIFFERENTIAL option.
Msg 3013, Level 16, State 1, Line 9
BACKUP DATABASE is terminating abnormally.

Can you retry the same once again. The steps which you are performing are correct.

From BOL:
A data backup taken with the COPY_ONLY option cannot be used as a base backup for differential backups. Differential backups taken later will behave as if the copy-only backup does not exist.

I tried the same thing on a different instance of sql and it worked fine Thank You all
