Hello All,
I'm new to this forum after read a few question error it given me little bit more understanding. But here's my problem I was create a database implement some tables than make a 'Full Backup' and input information on the table before make a 'Differential Backup'. I don't want restore a full database and just want to recovery specific table were deleted or removed. Please help........
Message show error:
Restore failed for Server 'SALES18'. (Microsoft.SqlServer.Smo)
Additional information:
System.Data.SqlClient.SqlError: The log or differential backup cannot be restored because no files are ready to rollforward.
Thank you very much.
A differential backup, though only containing changed data pages since the last full database backup, can only be restored in conjuntion with a full backup similar to using log backups. You don't have the ability to restore only single tables or objects, but you can restore at the database, filegroup, file, and page level. You can also restore up to a particular point in time from any of the backups (assuming you've restored the required preceding full, diff, logs).
Possibly the best solution for you in this case would be to restore the database using a different database name, then moving only the data you want into your existing database? Not sure if that's exactly what you're trying to achieve though...

|||Good Morning
Chad,
Thank you very much for your response.
Your answers it helping me understand the problem that generated by Sql Server 2005. I'm able to create a full, differential, and trans log backup and restore database to point in time but I have not done on filegroup and file backup/restore.
Questions: How do I determine the proper steps to do a restore data from disk only? Or do you know a particular website talk about 'software' do backup on tape?
My goal is to create a Maintenance Plan, Full,Diff, & TransLog backup and restore data. I'm anticipating to help the database team to do a performance backup & restore data.
Thank you against.
Ryan,
|||Hey Ryan. Sorry, but I guess I don't really understand the question. Are you asking how to determine the proper steps to simply perform a restore of available backups that have been taken, or are you asking for differences between native Sql backups vs. 3rd party backups (like LiteSpeed for example) vs. Hardware based solutions (i.e. Snapclones, etc.)?
|||Hi Chad,
This is a totally new for me to step in the SQL Server environment. Be honest with you try learn at much that I can to attached the skill apply to the company. If I like doing sql queries, what are the proper steps for me to do practice? Also, I'm thinking about to certify SQL Server but not sure which version is suitable.
Right now, my current tasks it to find out multiple SQL Server free disk space or been used. Notice there is a script .vbs to track the drive. Do you know any good site to do some research on?
Thank you

|||I am also facing this problem and getting this error message I don’t know why SQL2k is producing this error. I have just restored a backup for 30 March after that ideally restore window should show me the differential backups that are taken as base of 30 march but unable to see and when i try to restore the backup of 31 march by mentioning the device contain differential backup the I got this error
"System.Data.SqlClient.SqlError: The log or differential backup cannot be restored because no files are ready to roll forward. (Microsoft.SqlServer."
any one idea..
We r using SQL Server 2005 with SP2 (64 bit)and window service pack 2 also. A ntbackup utility is schedule to take backup every night 21:55 while differential backup is taken on 20:35
Many thanks in advance

In order to restore a differential backup you must have a database into which the full backup has been restored using the WITH NORECOVERY option. This prevents it from tidying up the database and making it available for use. If restoring using Management Studio then select the second Recovery state option (Leave the database non-operational).
You use NORECOVERY at every step of restoration of backups until the last one. The SQL Server BOL shows it in example B here: http://msdn2.microsoft.com/en-us/library/ms186858.aspx#restoring_full_n_differential_db_backups.

SQL Server Writer service When running, Database Engine locks and has exclusive access to the data files and also put a entry in "backup" table of MSDB databse which update the First and last LSN number against each database instance on MS SQL server.So the differentails backup becomes invalid becuase it seeks its full backup thru LSN number.
SO you get this messages so SQL Server Writer service should shutdown during wohle day so that it could not become invalid ur differential backup.
example :
your first backup thru SQL backup utility
DatabaseName First LSN LastLSN
AAA_Database 000012345 000012346
Differentail Backup off AAA_database
DatabaseName First LSN LastLSN
AAA_Database 000012347 000012348
your NTbackup utulity is running and SP2 of SQL and windows server has installed
DatabaseName First LSN LastLSN
AAA_Database 000012349 000012340
when urestore Differenail backup then u got the message deescribed in this thread. Because sql server detects that a latest full backup has done.
Solution is only shutdown ur SQL Writer Service.
