Automatically Restores All database ".BAK" Files

  • Sailor,

    is this already solved? All backups are in subdirectories in d:\sqlbackups right? are they all .bak files?

    I'll try to alter the script to solved the problem you are facing.

    All of my databases are in subdirectories so I changed

    SET @pathension = 'dir /OD/S '+@Path+'*20110814*.'+@Extension

    Msg 3201, Level 16, State 2, Line 1

    Cannot open backup device 'D:\sqlbackups\admin_backup_201108141900.bak'. Operating system error 2(The system cannot find the file specified.).

    So admin backup is in d:\sqlbackups\admin.

    What do I need to change to get it to work?

    Sailor here is the script which crawl up to all the subdirectories in the path specified. Do note that this is for VERSION 2000 OF SQL coz I dont have dev version 2k5. Just change the table structure for it to be useful for version 2k5. Test it first in your development server as I am not liable if you run this to your prod server right away. Reply to this thread if you received any errors or if ever you have any questions or clarification hope this script will be helpful to you as you have many backups in each sub directories :-). I also added a search string capability so that if you want backups with specific names then you can only select those files.

  • Hello Sir,

    I am using SQL 2008 and this beautiful script should help me a great deal as we are migrating from SQL 2008 and SQL 2008 R2

    I keep getting the error

    Msg 213, Level 16, State 7, Line 1

    Column name or number of supplied values does not match table definition.

    Msg 3013, Level 16, State 1, Line 1

    Msg 213, Level 16, State 7, Line 1

    Column name or number of supplied values does not match table definition.

    Msg 3013, Level 16, State 1, Line 1

    RESTORE HEADERONLY is terminating abnormally.

    Msg 213, Level 16, State 7, Line 1 is terminating abnormally.

    Msg 213, Level 16, State 7, Line 1Which I think it might the output of RESTORE HEADERONLY does not fit into the scheme defined? Do you have updated script for SQL 2008?

    Please help

    Greatly appreciated

  • Hi

    Thanks for the script, it is very helpfull, I just have one doubt, since i haven't gone deep into the script, is this script taking the last differential backups? in my case I'm doing differential backups every day and a full backup on sundays, a new backup file is made once a new week starts, following this name structure: YYYYMMDD_HHMM_NumerofWeekInTheYear_DBNAME.BAK. EXAMPLE: 20110807_1000_42_Employees.bak; therefore, one backup file has 6 differential backups and 1 full backup, that's why I'd like to know if it is getting the most recent differential backup or if I need to modify the script ... sorry if I misspelled some words, I'm not an english speaker, and I'm also starting into the Databases world. 🙂

    Hi kindly view page 5 of this thread post of Steven Webster-494809 or stakes 🙂

    P.S.

    Ohh another thing, I think I browsed an article regarding incompatibility of SQL 2008 restoration to SQL 2008 R2 (or vice versa). I maybe wrong but it will not hurt you to just check and verify

    Hi hiram,

    The order of the backup file is based on the result of the cmdshell operation in the script. You can try running the script (just dont uncomment EXEC (@restoredb)) and you will see which backup will be restored first. Compare the result to the folder where the backup resides.

    P.S.

    Don't worry I am not a pure English speaker as well 😉

  • Hello, I've gone deep into the script and I made some changes in order to take the last full and differential backup made. It still needs some readjustments but by now it is helping a lot :D.

    Thank you again for your Script and If you want i can share the modified script

    Hello again, this is the modified script, I just made some readjustments in order to do what I needed. It still needs some readjustments.

    Here's the scenario: We are doing Backups every day of our working DB's at 1:00am. Only on Sundays a Fullbackup is performed and the next days a differential backup is made. Therefore, a backup file is created every week containing a Fullbackup and six differential backups.

    As you can see I replicated the steps where the fullbackup script is made and the differential but performing an EXEC at the end of each one.

    I know I'm doing somethings wrong, or that some other parts of the code could be improved, so please I would appreciate any suggestion and comments about it.

    Hi does the script give you error/s when executing? or are you already using it?

  • Hi, the script is working fine, it doesn't display any errors, but I'd like to know if there are some parts of the current code that could be improved. I'd also like to add something to evaluate which are the most recent backup files, and take those for restoring, since I have backup files from several weeks in a single folder. I currently added a code to delete the backups from cmdshell table that weren't made the current day:

    SET @DATE = (CONVERT(VARCHAR,DATEPART(DAY,GETDATE()))) + '/' +(CONVERT(VARCHAR,DATEPART(MONTH,GETDATE()))) --Gets the current day and month

    -- I added this part to eliminate the backups that were not made the current day

    DELETE FROM cmdshell

    WHERE FEntry NOT LIKE @DATE + '%'

    but there are sometimes on which the most recent backups are from 1, 2, or more days ago, and I'd like to dynamically get them from cmdshell table, do you have any suggestions??

    Thank you very much for your time 🙂

  • So what you want is to restore the latest backup? regardless if the backup is 1 or 2 days ago as long as it is the current one? are you restoring...

    only 1 backup?

    1 diff and 1 full?

    1 full?

    1. you can retain (in the cmdshell table) the max date from your script

    2. you can look per filename (which is your format) or per system date (the first 20 chars of the result in cmdshell table)

  • hi :

    i have one my db bkp files in format t1_db_201402031813.bak

    but when i run..i am getting the following error..

    any help would be greatly appreciated...

    i need to restore close 200 dbs..

    Msg 213, Level 16, State 7, Line 1

    Column name or number of supplied values does not match table definition.

    Msg 3013, Level 16, State 1, Line 1

    RESTORE FILELIST is terminating abnormally.

  • Here is another version that should work pretty well.
