SQL Server 2008 :: Finding Backup File Size In Advance?
Mar 8, 2015
My backups are failing sometimes.My db size is around 400 GB and we are taking backup to the remote server. Free size available on the disk is showing 600 GB but my database full backup run more than 10 hrs and failed. The failure reason is there is not enough space on the disk.
What could be the possible failure reasons? It has more than the the database size on the backup server but why it is showed that msg on the job failures. I noticed same thing occurred couple of times in the past.
Is there any way to find how much the backup file will be generate before we run the backup job?
i.e. If we run the full backup of test1 database now, it will generate ....bak file for that test1 db
currently we are using maintenance plan and with compression (2008R2) and the database has TDE enabled

I have issue with my DATA file ( MDF) .. The usage is 99.87% for database DB1 . File size is 3 GB . How do I reduce it ?
I have tried to shrink it by changing the recovery from FULL to SIMPLE and set it back to FULL .
I notice the index Defragmentation is high ..
Can I change the Initial Size into 1 GB for example ?

We have installed SQL Server 2008 R2 SP1 instance and it's having Share Point 2010 databases.
We have 2 dedicated drives for Tempdb on SAN with 50 GB space. Both tempdb data & log files are created with default size. I would like to presize them.
What are the best values to start with?
U ->Tempdbdata having tempdb.mdf file
V->Tempdblog having templog.ldf file

I am getting following error:
"The log in this backup set terminates at LSN 9566000024284900001, which is too early to apply to the database. A more recent log backup that includes LSN 986000002731000001 can be restored."
If I am missing to restore previous log backup file, how to find which LSN mapped to which log backup file (.trn file name)? Another word looking at LSN can we tell which log backup file is missing?

I have a log file that is approximately 50 GIG. I backed up just the log and the file size of the .bak is 192 GIG . Why is this? Shouldn't it be closer to the 50 GIG.
Normally I wouldn't let log grow this much. But we are in process of getting new server up and running and don't have backups going yet. They are working on getting that up and running this week.
So I did a log backup to give me back some log space for now but was concerned when I saw the size of the .bak file.
When I view media contents of the backup device it shows one tranaction log back up and size of 192 GIG.
What is up with this. I know in SQL 2000 the log backup files where never this big. they were about the size of the log itself.
Any ideas?

Is the name of the last backup file recorded anywhere in SQL2K? I do backups every 2 hours, and want to restore backups from database A to database B once a day using the latest backup. Unfortunately the backup files don't have the time the backup started (e.g. 1600), but have the time they ended (I presume); e.g. 1604.
I want to automate the process; any suggestions on how to find the name of the last database file?
TIA,
Al

It's OS / SQL related. I backup to a UNC device, and frequently get a network related error - but not always. And the error is also OS related...
The scene: 64 bit Windows Server 2008 hosts 64 bit SQL 2008 Standard, and devices are created to point to 64 Server 2008 Server B (ServerBSQL_backupsdvc_DB.bak). The database is backed up daily, on a job, and when run the following error is returned:

The file is generated, the same size as a successful backup, but the job terminates unsuccessful.I have tried to delete the devices' file, and then the backup usually succeeds. This may point to a permissions' type error, but the user the job is run under is a domain admin. The destination server is not unavailable during this time, and the network shares also remain active throughout the excersize - although I haven't got a way to "prove" this.
I have a few databases that backup to the UNC described above (different files) that don't fail..My SQL2000 server backs up it's databases to the SQL2008 server, and those backups don't fail with this error.
My research has led me to understand that the 64bit OS tries to buffer the files it receives from another server, and I was wondering if this could be influencing the backups as the destination server is also 64 bit Windows Server 2008.
##20090812## UPDATE
I tried another way to do the backup; with the same results:
Backup database Infovest to disk = '
iscsrv-dcm04
iscsrv-sql01_backupsdvc_Infovest_Z.bak' with INIT,STATS=1

I have a sharepoint content database in sql 2008 R2 (WSS_Content) that is at 230Gb size, but has 40% of it is empty space. Â This is because we have removed a large amount of old content from sharepoint. Â The log file is fine. Â I have 60GB left in my drive that host the database files. Â I would like to shrink the datafile to get disk space back. Â I found that under the files property, the WSS_Content data file's initial size is 228702 MB (220 Gb or so). Â
When i try to do a shrink file (data file) from management studio, i see the 60 GB of drive space keep dropping. Â So i have to kill the process. what i should do to reduce this data file.
why it keep using up all the free space in the drive when i try to shrink the data file?

I have installed the sql server management studio express for my express edition of studio 2005 for backup purposes.
I need to automate backing up my database.
I created a backup script and have successfully got sched tasks to backup each night. the problem is it is not overwriting the previous data. My first backup was 1 gig, the next night the file was 2 gig, the next it was 3 and so on.
This is not due to that much data being added to the db.
When I go to restore, I have the option to restore any of the 3 backups. I would like my backup to be a single image of the database at the last backup time. How can I do this?

I'm having a problem. When I use the SQL query to make a backup of the database, it worked fine. But everytime I use it, the backed-up file's size kept growing in size. Say I have the file, test.bak whose filesize is 450 MB then I run a new backup to overwrite the existing test.bak file, it just end up as 900 MB. If I run it again, it become 1350 MB and so on.
Is there a way to prevent that from happening?

finding the database size from the backup file.I have SQL 2012 backup file, is there any way to find the estimated database size from the backup.I tried restoring , i got an error saying " no space need additional xxx bytes " ...does this error gives the exact space needed to restore ?
One more question....one of the backup file size is 7.2 GB, when i try to restore it ....it throws error saying it needs 292GB extra space while only 100 Gb is available. How come 392 Gb sized database becomes 7.2 Gb .bak file ?

In a recent attempt to keep the size of my transaction log files down I altered the schedule of my SQL Server log backups from running every 15 minutes from 07:00 to 19:00 to run every 15 minutes.My company also uses a Dell AppAssure application to also take backups. The backups are of the entire drives so I don't this will affect the size of my SQL log files but I did notice that AppAssure has a tick box to truncate the SQL logs so it made me wonder that it could affect the size of my log file. The Appassure backups currently run every 15 minutes from 07:00 to 19:00. I'm wondering if I would be able to maintain my log files at a smaller size if I ran this every 15 minutes from 07:00 to 07:00.

I need to find a way to identify SPIDS where queries are connected to certain databases using the 4 dot notation instead of actually being connected to the database in question.
For instance, I connect and my default database is MASTER. In MASTER, instead of typing USE MyDb ahead of my query, I just type my query as:
SELECT Col1, Col2
FROM MyDB.dbo.MyTable
The above is the simple scenario. We usually have queries connecting 3 or 4 user dbs together. So database1 might have a query pointing to database2. What I need is a way to identify the SPIDS that are connecting to database2 despite being in database1.

SQL Server 2008 r2 - 6 GB memory...I attempted a backup on a 500GB database but it was taking way too long. I checked the resources on the box and saw the CPU at 100%. I checked the SQL Server activity log and saw a hung query (user was not even logged on) that had multiple threads so I killed it and now the CPU utilization is back to normal.
Trouble is, now all of the threads in the activity monitor for the backup show 'suspended' and the backup appears to be not doing anything.

Ok following scenario
create table dbo.ADAssets
(Computername nvarchar(max))
insert into dbo.ADAssets
values
('AIRLBEOF3565 CNF:4e926e06-6f62-4864-aebd-6311543d',
'AIRLBEOF3565')
So if execute the following
select Computername
from dbo.ADAssets
where Computername like
'AIRLBEOF3565%'
I get both records,but if I do this
select *
from dbo.ADAssets
where Computername in
(
'AIRLBEOF3565 CNF:4e926e06-6f62-4864-aebd-6311543d',
'AIRLBEOF3565'
)
I only get AIRLBEOF3565
So the big picture is that I need to compare 2 tables to find records that match & don't but that I get matches that shouldn't be & matches that aren't.

This question is a long shot because it requires familiarity with a specific application called ChefTec which is a program for the restaurant industry, but I'm giving it a try because I have nowhere else to go to get the information I need. I am the developer for a competitor of this program, and some ChefTec users want to switch to our product and have their data, which is in SQL Server 2005 or 2008, converted.
My plan is to create a utility that the users could run to convert the data (written in Delphi, though that doesn't really matter). The problem is that I can't determine the connection string that ChefTec uses. It doesn't seem to be stored anywhere obvious (an ini file or the registry). When ChefTec is installed it either installs SQL Server or gives the option of using an existing instance, but there's no way for me to know how it was set up on any given machine. The program must be using some internal logic to create the connection string but that's not accessible to me.

Hello,
I apologize in advance if this seems like a relative easy answer, however, I can't find it anywhere, and I can't figure it out personally, I am relatively new to SSIS and C#.
I am attempting to write in C# a simple program, where I am taking a table from an OLE DB Source and transfering it to a comma delimited flat file.
I have been trying to work through samples and other methods of help, but I continue to get stuck, and this is my latest problem.
When trying to excecute I get the error: No column was sepcified to allow the component to advance through the file, for my flat file destination.
I know what this means, I just do not know how to fix it.
Below is my code so far. I highly doubt my code is the best it can get for this type of example, so if you see anything that I do not need in the code for it to perform what I want it to perform, please let me know.

I'm trying to understand what is happening to one large table.
In a DB SQL 2008R2, I'm trying to track a rapidly increasing DB size. It's due to one table recently added.
Despite the table's no rows increasing its size reduces after a scheduled re-index.
I've recorded the space used by this table by recording EXEC sp_spaceused 'tableName'
---
NoRows reserved data index_size unused
128864512300384 KB 2290928 KB9432 KB24 KB AFTER reindex
128864515406232 KB 5366184 KB39280 KB768 KBBEFORE reindex
N.B. The only thing I'm aware of happening in the time period is a reindex as part of scheduled task. I could be missing something else happening.
The table has only one Index the PK which is clustered, No Fill factor is specified. The Server Default fill factor =0.
I read fillfactor=0=100 Will always try and fill the pages so space used will be minimised?
After running the reindex the index fragmentation is v.low. I've not recorded the fragmentation before reindex.
I can see the Data is not added in Clustered index order.
