Backup/Restore From/to Compressed Files
Apr 24, 2007
Hi everyone,
already tried this in other SQL forums, but maybe i have some luck here.
I need mainly to restore database backups from customers. They arrive in all kind of formats (zip, rar, gz). I'd like to be able to restore those directly from the compressed file, because i'm talking up to 7GB rar files which take a while to uncompress in a separate step.
I'm working for 6 years in R&D environments, but mostly on Linux/Oracle where this is an easy task using pipes, but i haven't found a sinlge web page, post or even script to do this with MSSQL. The VDI is not really what i'm looking for, so aren't backup software like SQLBackup, Litespeed etc. because i can't force the customer to use those.
Anybody any idea or even the same problem maybe with solution?
Thx.

I got full backup on daily schedule its taking more space on Drive because each file has more than 25GB.I am using SLQ server 2008R2 so I'm looking to take the backup with compression instead of uncompressed Backup. What are the impacts of compressed backup. Is there any problems with compressed backup while restoring the backup file.

I am trying to read a 36 byte files that contains compressed data. I create my Flat File data source and SSIS reads it fine UNTIL it hits a x00 in the file. Then it stops reading and I can't get any data after it. There is data after the x00. Here the entire hex string: C7 C7 CF 6A 00 00 05 02 3D 03 21 01 E0 02 00 00 00 00 00 00 00 00 3D 3C 1E FD 02 C8 00 00 00 AE 41 E3 28 7C
To test, I changed the two x00 in bytes 5 and 6 to x01 and SSIS read until the next x00.
Anyone have any ideas?
Thanks,
Jack Lavender

Hello,
I am attempting to restore the database from within VB.NET application I am making the following 3 calls:
RESTORE FileListOnly FROM DISK = 'C:MyDatabase.dat'
USE Master RESTORE DATABASE MyDatabase FROM DISK = 'C:MyDatabase.dat' WITH NORECOVERY, MOVE 'MyDatabase' TO 'C:Program FilesMicrosoft SQL ServerMSSQLDataMyDatabase.mdf', MOVE 'MyDatabase_log' TO 'C:Program FilesMicrosoft SQL ServerMSSQLDataLDFMyDatabase.ldf', REPLACE
RESTORE DATABASE MyDatabase FROM DISK = 'C:MyDatabase.dat'
using SMO. This logic works fine with small *.dat files, however when using *.dat file of about 4Gb I get an error on the 3d restore database call:
ExecuteNonQuery failed for Database 'master'.
An exception occurred while executing a Transact-SQL statement or batch.
Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.
Operator aborted backup or restore. See the error messages returned to the console for more details.

The same program/logic also works fine when I use MS SQL 2005 and it runs fine from MS SQL 2005 Query Analyzer for both 2005 and 2000 databases. There seem to be only problem with MS SQL 2000 from within VB.NET. Anybody has any idea? I'd appreciate any response. Thanks

Hi, I am trying to lean ASP.NET. So I was trying to install SQL Server too. But, I could not install. The aleart box popped up:
"SQL Server set up cannot install files to the compressed or encrypted folder: C:Program FilesMicrosoft SQL Server"
Before this, I also got a warning that the hardware of my computer does not meet the hardware requirement.
I would like to know how I can install SQL Server into my computer. Or, shouldn't I do that? To learn ASP.NET I want to have a database ready. If I can not use SQL Server, I may try Access or something smaller...
Thanks in advance.

Noticed weird activity today with pull merge.
When your snapshot is set to be delivered via ftp and compressed in a cab file. If you add a new article to your publication and re-run the snapshot the agent will be unable to pull the snapshot down as it for some reason doesnt think its compressed. It is failing to find the scripts it needs inside the cab file despite the cab file existing in the correct location.
Here is the error.

I am looking for a SQL Backup/Restore tools which can restore multiple environments. Here is high level requirements.
1. We have 4 DBs, range from 1 TB - 1.5 TB Each Database. When we restore to QA, DEV, or Staging, we usually restore 4 of them.
2. I am looking for the speed to complete restoring between 1 - 2 hours for 4 DBs.
I am evaluating the Dephix Software but the setup is very complex and its given us a lot of issues with Windows Authentions, and failure in the middle of the backup. I used Guess Software many years ago but can't find it on the web site any more. Speed is very important for us mean complete restoring as fast as possible. We are on SQL 2012 and SQL 2008 R2.We are currently using NETAPP Technology and I have Redgate Backup Tool but I am mainly looking for fast Restore Process.

I have the need to delete old backup files via TSQL job. Found this solution online:
PushD "
emoteservershareDIFF" &&(
forfiles -m *DIFF*.sqb -d -1 -c "cmd /c del /q @path"
) & PopD
It works remotely if I run it via command prompt. But when I add this to a TSQL job on my remote SQL instance, it runs without deleting anything. What I'm missing?

I should restore a SQL Server 2005 Database from backup. The backup contains three files, named user.bak0, user.bak1 and user.bak2.
How is the syntax of the restore filelistonly and the restore database ... ?
I usualy write
restore filelistonly from disk = 'path and filenam.bak'
restore database. zy
from disk = 'path and filename.bak'
with replace,
move.....
move....
This works but I cannot use it with a splitted backup file. The files are much too big to put together to one file.
Thanks in advance for any help.

I neglected to backup the transaction log as part of the process of backing up the database. Now i only have the backup file for the database and no transaction log backup. When i try to do a restore on the database, i get the error on a "tail log missing" message (which i'm assuming is that it's looking for the t-log backup?).
Is it possible to restore or even restore to a new database? I'm only looking to retreive data from 2 tables within the backup file.
Thanks!

Currently we use a SQL maintenance plan to do a full backup of all our databases daily (about 40 databases on our production server). As you can imagine, this eats up disk space quickly so currently we manually zip the backup files and/or move them to an archive drive. I considered writing an application to walk through the backup folder structure and zip any .bak file it finds, but I know there are some third party tools out there that will backup/restore a MS SQL database.
I was wondering if any of these also zip the backups once they are created. Any recommendations or suggestions are welcome.

I'm the DBA in an environment with approximately 240 identical (structurally) MSSQL 2000 databases in an environment. Each one of these databases are different business units around the country. For each of these DBs, I have my backup schedule set up to do a full backup every friday night, along w/ doing a transactional every 4 hours in between. Every once in a while (about once every 3 weeks), I get the call to do a restore to pull some piece of data that some end user accidentally deleted or broke. Now most of the time it isn't a big deal, because I can use enterprise mgr to restore to a new DB from the live backup set of the database in question.But, several of the databases seem to have an issue where (for some reason) my predecessor renamed the logical file names of the data and log files to various goofy things. It doesn't affect their operation, but when I try to do a 'restore from database,' it gives me a bunch of big fat errors. This is also the case when the backup I want to restore something that has been written to tape and has been rolled out of the backup history.SO... basically for these databases, now I go into Enterprise mgr and first restore the base .bak file to a new database, leaving it marked 'read only' and 'able to restore additional transactions.' I then have to do the same thing with restoring each additional TRN file, all the while making sure I don't forget to set the 'able to restore additional transactions.' Whenever I forget to set that I have to start all over. And honestly, it happens more often than not when I have to restore 5 days out from the .bak file, which means that I have restore 30 trn files on top of the .bak. Not hard, but incredibly tedious.So here's my idea. I know I can script restores thru QA. I've been looking quite a bit at this MS doc (http://www.microsoft.com/technet/prodtechnol/sql/2000/maintain/sqlbackuprest.mspx#E2AA) and have come up with some good ideas. What I want to eventually do is create a script that you can just paste the .bak file and the list of .trn files. The script basically creates a temp table w/ those file names and cursors thru the restore process. The cursor part is easy for me, I'm just not sure about scripting the trn restore. The MS doc is a bit vague and really only shows the Enterprise Mgr method.Here's what I've been playing w/ so far for restoring the base .bak file:restore database restore_dbname --NAME OF NEW DBfrom disk = 's:mssqlackupuserdbnamedbname_db_20060120184 1.bak' --PATH TO BAK FILEwithmove 'pm65mr1_default_data_OldDBName_Data' --LOGICAL FILE NAME OF ORIGINAL MDFto 'I:MSSQL$MSSQLSERVER2Data
estore_dbname.mdf' --PATH TO NEW MDFmove 'pm65mr1_default_data_OldDBName_Log' to --LOGICAL FILE NAME OF ORIGINAL LDF'U:MSSQL$MSSQLSERVER2Log
estore_dbname.ldf' --PATH TO NEW LDFpartial, recoveryI think I'm pretty close with this, but I'm not really sure how I can stack the trn restores on top of that. Any ideas? I've been putzing around the web and so far haven't been able to come up w/ anything really useful.

Hi,
I have a database that over time has become spread over different files, file groups all of various sizes.
I want to restore this database to a different set of files/filegroups and evenly spread.
It appears that I can only resotore a database to number/of and size of files from which it was backed up..
I want to redistribute a 40GB file, using EMPTY is taking for ever and then eventually fails.
What can I do?
Thanks for your help

First, let me say that I have already reviewed information posted by experts within the chat area.
Someone completely deleted my SQL Server 7 database. I retrieved the .LDF and .MDF files from a network backup. Now I am trying to attach the database. I have tried this without creating an instance of the database by using the attach stored procedure to attache the .LDF and .MDF files I retrieved from the network backup. Also, I have tried it by creating an instance of the database and doing a detach of the newly created db .LDF and .MDF files and an attach of the .LDF and .MDF files I retrieved from the network backup. Neither of these approaches have worked.
Here is what I have tried in the Query Analyzer, but to no avail:
For the following example, I created a database instance called 'qarun_diamond_48_brett' with brand new .ldf and .mdf files and then tried to detach and then attach the .ldf and .mdf files from the network backup:
use master
go
sp_detach_db
'qarun_diamond_48_brett', 'F:APPSSQL 7.0DatabaseDataqarun_diamond_48_brett_log.ldf'
Message: Usage: sp_detachdb <dbname>, [TRUE|FALSE]
use master
go
sp_detach_db
'qarun_diamond_48_brett', 'F:APPSSQL 7.0DatabaseDataqarun_diamond_48_brett.mdf'
Message: Usage: sp_detachdb <dbname>, [TRUE|FALSE]
I tried the following attaches of the retrieved/recoverd .ldf and .mdf from the network to the newly created db instance. That didn't work, so I tried attaching to a db that had not yet been created.
use master
go
sp_attach_db
'qarun_diamond_48_brett2', 'F:APPSSQL 7.0DatabaseDataqarun_diamond_48_brett2_log.ldf'
Message: Server: Msg 1801, Level 16, State 3, Line 1
Database 'qarun_diamond_48_brett' already exists.
If I use a different db name I get the following error:
Server: Msg 5105, Level 16, State 13, Line 1
Device activation error. The physical file name 'qarun_diamond_48_brett' may be incorrect.
use master
go
sp_attach_db
'qarun_diamond_48_brett2', 'F:APPSSQL 7.0DatabaseDataqarun_diamond_48_brett2.mdf'
Message: Server: Msg 1801, Level 16, State 3, Line 1
Database 'qarun_diamond_48_brett' already exists.
I have also tried these statements wtih the EXEC sp_attach_db and EXEC sp_detach_db commands from within the Master db in Query Analyzer.
Any help would greatly be appreciated.
Thanks,
-Brett

Hello,
I have a SQL 2000 DB. Current tables in sql 2000 DB are in single file. I am planningto migrate the DB to sql 2005. I am going to partition the tables in sql 2005 and have multiple files. What is the best way to do this? Would backup/restore work? If I restore onto sql 2005 from sql 2000 backup, will the tables spread over different files automatically or not? Any ideas will be appreciated...

I selected Restore Database and chose From Device, and selected the backup location on J: drive and selected the backup file which has no extenstion. I checked the checkbox next to the backup set to restore. Click OK and then I get this error message:

Hi I am operating my databases under "trunc log on checkpoint" mode as I do not need point of failure recoverability.I was performing a recovery test using a backup which resulted in it being unsuccessful .Error Message received was
"Recovery has failed because a nonlogged operation could not be redone.Use the RESTORE statement to restore all data in filegroup PRIMARY to a pt beyond the nonlogged changes"
Isnt sql*server supposed to prevent a non-logged operation while a backup is in progress?Also how do i prevent such a situation from recurring.
If i switch to single user mode before a backup how do i prevent exisiting users from accessing ... without bouncing my sql*server?
