How To Verify The Integrity Of A Back-up File Prior To Restore?
Mar 22, 2007
Hello,
I have some C# (.NET 2.0) code that performs back-ups and also can perform restores of back-up files. I would like to validate the integrity of a file prior to initiating a restore operation. In other words, I want to know, before I try to restore, if the file is just a random file (picture, work doc, zipped backup, etc.) or if it is a valid SQL backup file.
I would like a way to check a file before attempting to restore it. I want to be able to tell that this is a valid SQL backup file and not just some random file before I attempt a restore.
I have a maintenance plan set to back up my 2 primary databases, one about 1 GB, the other about 2GB. I have about 4 GB available on the back up drive. I have set it to delete old backups more than 1 minute old. Problem is, the first night it works fine, the second night it sometimes it refuses to delete the old and therefore does not have enough space to complete the new back-up. Does anyone run into this before? Does it complete both back-ups THEN erase the old, in which case I need to have about 6GB available? Sometimes it works and sometimes it doesn't. It can be going along fine for weeks then stop working. Any info or links to how this is supposed to work would help.
I have a compact pc program that uses a sql server database (sdf file). I want to check the database integrity when program starts so I added a call to veriy method of SqlCeEngine
I have a scheduled job that will do a database restore at given time every day. Sometimes I run into a situation where some people leave themselves logged on to the database, which prevents the job from running.
Is there a way that I can set up my job to include killing any open processes against the database that I'm restoring prior to the restore being done?
In SQL Studio, I can go to the restore window and the click "verify backup media". This would check the restore plan listed in this window and check if some of the file are missed.Is there any way to reach this with TQSL? I know there is a "restore verify" command, but this will only verify one backup/file and not the complete restore path. I'm looking for a TSQL solution which is able to control that all necessary backup files are still present on the file System and not moved or deleted (e.g through cleanup task).
Hello,I'm trying to create a simple back up in the SQL Maintenance Plan that willmake a single back up copy of all database every night at 10 pm. I'd likethe previous nights file to be overwritten, so there will be only a singleback up file for each database (tape back up runs every night, so each daysback up will be saved on tape).Every night the maintenance plan makes a back up of all the databases to anew file with a datetime stamp, meaning the previous nights file stillexists. Even when I check "Remove files older than 22 hours" the previousnights file still exists. Is there any way to create a back up file withoutthe date time stamp so it overwrites the previous nights file?Thanks!Rick
Is there a way to verify the version of the files that are used to connect to SQL 2005?? This stems from an ongoing problem I am having with having SQL 2000 and 2005 on the same machine... It has come done to the client connectivity files....
I have a problem that I haven't been able to solve it. At the end I am confused I need some clarifications.
Background: I am using full back up recovery plan. I am getting daily full back up and every 15 minutes log_back up. I created these back ups by using Database Maintenance option. However I have been trying to restore the log_back up, but I couldn't achieve it.
Question1- When I take log back up do I have to activate "Remove inactive entries from transaction log" or not??
Info: When the log back up was done it deletes the latest 4th one. I have done this without no reason. Should I keep like that or should I allow the files being deleted right away after transaction logs backed up?
Question2- I cannot restore the log files I don't know why? I have followed every description that I read. After I restored full back up with NOREOCVERY the database hangs out says "loading" but it doesn't do anything and when I try to restore it doesn't accept the latest log back up file and it urges me to put newer file than I have but ıt is only latest log back up that I have Why does this happen?
Everyone, I simply would like to know if ER Diagrams (under Database -Diagrams) on SQL Server and removed once the database is updated via a backup and restore. Thanks, Saurav
I had to transfer my database from one server to another. Both are running SQL 2000. I backed the database up and moved it to the new server however when I try to do a restore I get the following message:
The media set for database "xxx' has 2 family members but only 1 are provided. RESTORE DATABASE is terminating abnormally.
I did some searching and found a couple of posts that mentioned something about the back up including 2 files.
My problem is that the machine I backed this up from crashed when it was shut down and would not reboot so all of the data and the original database do not exist. Is there any hope of restoring this database. It is pretty critical.
Hi i am backing up a database, copying it to a shared folder on a different computer on same LAN, then restoring it on the different computer. it used to work fine untill last few weeks.

Is it possible to uninstall SQL 2005 and reinstall SQL 2000 if I need to? I would obviously have a backup copy of the database(s) from the SQL 2000 version. If so, is this a major ordeal to perform?

I need to back up a production database on one server and then copy it to a test server wherel it will be restored. The problem is that I don't know where to move the file to on the production server before I restore it. Is there a special folder I need to copy the file to? I see a folder named ProgramFilesMicrosoft SQL Server but beyond that I have no idea where to copy the file so that it can be restored?

I am able to back up to a logical device and restore it from logical device through T-SQL code.

1) Need a simple routine or system function for testing for or verifying the existence of a file or folder on the local server's file system. Returning a simple boolean value or 1 or 0 would be fine.
2) Need a syntax and use description of the new "master.dbo.xp_create_subdir" function ... anyone have some documentation or links? MS technet and MSDN have nothing.
hi, I would like to know the correct reaction for a crash in both senarios. First senario, I made a full back up at 6 am , then scheduled sql server to make transaction log back up every 2 hours (8,10,12,2 pm,4,6,8) . If I have a crash at 12:30. How would I resotre the data in the first senario....Can I restore the full back up done at 6 am then restore the last transaction log backup ( which is 12 Noon ) . I am not sure If I need to resotre the whole tran from 6 am till the time it was crashed.
Second senario,
I made a full back up at 6 am, then scheduled sql server to make Incremental backup every 2 hours (8,10,12,2 pm,4,6,8) . If I have a crash at 3:00 pm. How would I resotre the data in the second senario. ....Do I restore the full backup at 6 am then restore each incremental backup backwords ( 2,12,10,8)
AS you can see, I am not sure how to deal with this issue, I do appreciate your feedback.

I am maintaining a .net 1.0 asp.net web application that accesses a SQL server 2000 database. I need to backup the database and then restore it on a laptop. Currently it resides on a server. The problem is that on the server they are using sql server 2005. If I backup using 2005 and then try and restore this database using SQL server 2000 or 2005 on the laptop, I get an error message. "Too many backup devices specified for backup or restore; only 64 are allowed. RESTORE DATABASE is terminating abnormally. What can I do to restore the database? Must it be backed up with SQL server 2000 and then restored with SQL Server 2005? Please help!

I am looking for a Sql query to verify the inserted values from one table(in CSV file) with another table(in sql database)
For example: I have below Values column that is present in once CSV file, after my data migration the values get stored in Results table under Message column.
I need to very whether values(1X,1Y) are inserted in Message record "successfully inserted value 1X"
Values (CSV) 1X 1Y
Results Table(SQL) CreatedDate                  Message 2015-08-04 08:45:29.203  successfully inserted value 1X 2015-08-04 08:44:29.103  TEst pass 2015-08-04 08:43:29.103  successfully inserted value 1X 2015-08-04 08:42:29.203  test point 2015-08-04 08:35:29.203  successfully inserted value 1Y 2015-08-04 08:30:29.203  Test Pass 2015-08-04 08:28:29.203  successfully inserted value 1Y
If all values are inserted:
Output: All values from values table are inserted successfully Total count of values inserted: 2 If only few values are inserted, example only 1X from Values table is inserted in Message
Example: Results Table CreatedDate    Message 2015-08-04 08:45:29.203  successfully inserted value 1X 2015-08-04 08:44:29.103  TEst pass 2015-08-04 08:43:29.103  successfully inserted value 1X 2015-08-04 08:42:29.203  test point
Output: All values from values are not inserted successfully in result table. Total count of values inserted: 1 Missing Values not inserted in results table are: 1Y

Greetings,Our former SQL Server 2000 DBA backed up everything in a single diskfile. By everything I mean, full backup, differential backup andtransaction logs. See below for details of how the backup is currentlyset up. When I did 'view contents' of DBBackup, I saw it contained themixture of log, full and diff backups of verious dates. She has quit.Other coworkers said (in a not-sure tone) she was able to restore thedatabases from such a single file, although nobody ever saw or knew howshe did recovery. My knowledge about SQL Server, especially regardingits backup/restore is limited. But I've ever worked with otherdatabases, e.g. Oracle, MySQL and Postgres. I think log backups, fullbackups and differential backups should be completely separated. Also,in each type of backups, each database should have its own backup file.Please advise.=====Log backup:CREATE PROCEDURE sp_lbackup ASBackup log AGEP To DBBackupBackup log careerfairs To DBBackupBackup log CoEdocuments To DBBackupBackup log committee To DBBackupBackup log conference To DBBackupGOFull backup:CREATE PROCEDURE dbo.sp_fullbackup ASBackup database AGEP To DBBackup WITH INITBackup database CoEdocuments To DBBackupBackup database careerfairs To DBBackupBackup database committee To DBBackupBackup database conference To DBBackupGODiff backup:CREATE PROCEDURE sp_diffbackup ASBackup database AGEP To DBBackup with differentialBackup database careerfairs To DBBackup with differentialBackup database CoEdocuments To DBBackup with differentialBackup database committee To DBBackup with differentialBackup database conference To DBBackup with differentialGO=====Thanks in advance for any help,Bing
