Dec 4, 2014I found it pretty interesting. I checked the size of a database, before implementing database compression across all the user tables in a database. And Post implementation of compression too I checked the size of the database.
I did not find any difference. But if I expand the table and check propetires->storage and I can see that PAGE compression is implemented across all the tables, but no compaction in the size of the db. It still remains the same.
Compression
Apr 2, 2004Hello,
I have been wanting to compress my database. I am not really sure how this is done. I was looking on Enterprise Mangr. and if you right click on the db and go to all tasks, there is an option to shrink database. Is this the way you would compress your database, or are there other ways of doing this?
Thanks for all the help.

Message Compression
Sep 15, 2005We have run some tests on our application. Average message is about 2.5 MB. Messages are send once every 30 minutes. This is 3.5 Gb per month for one site. Now we already have three sites that will be sending this messages. This will be VERY high load on the WAN channel, and will cost us a LOT of money .

View 3 Replies View RelatedDatabase Backups && Compression
Jun 19, 2007Hi All
I have a database which is 72GB, which is backed up every night as part of the maintenance plan. I have plenty of storage space, and the server that runs the database is fairly powerful (quad-processor 3.2ghz, 64bit, 48GB RAM) and is part of an active-passive cluster. The database backup is also copied to a SAN location.
My issue is with the size of the backup file. As part of the Disaster Recovery plan, I need to copy this database backup file accross the network to a remote site, so that in the event of a disaster at the site, business can continue at the remote site after restoring the database backup file. However, my database backup file is so big that I cannot copy it accross the network in time for the next morning. I have tried using WinRar and have managed to achieve a file about 20% of its original size, but it takes 2 hours to produce this file.
Is there any recommended reeading for this type of issue? Log shipping / mirroring has been investigated and will be part of the DR model but the 'powers that be' insist on having a full copy performed to the remote site.
Any suggestions? Thanks in advance guys n gals :-)
Use Backup Compression On Few Servers
Jul 26, 2015I am wanting to use backup compression on a few sql servers (2008R2 and 2012). I have never touched compression before and always just gone with the default.I use Ola Hallengren's scripts to do the backups which, if not specifically specified, will use the server default.Backups (FULL and LOG) have been happening successfully on these servers for years.SQL won't care that the previous backup in the set was uncompressed or that the hourly transaction log backups previously taken were uncompressed?Restore statements (T-SQL) will be identical?From everything I am reading it is simply a case of setting the configuration and acting like nothing changed but I just wanted to be 100% certain.1 of the servers is a SharePoint backend.All of the backup files from all servers are picked up by Commvault backup system.
View 4 Replies View RelatedPrint Compression When Deployed
Dec 14, 2006I have a report being utilized for return address labels, conforming to Avery 5167. I have tried designing both as a table and as data in rectangles. Since these are return labels their is only one instance of data replicated for all textboxes, therefore the columns are of consistant length.
The report has seven columns of precise measurement, the data filled colums are set as 1.75in, 0.25in, and between the data columns are blank columns set to .3125in, 0.25in. I have also tried to fill data into the blank colums and set the font color to white. All report margins are set to 0in and the table location is 0.04167in, 0.125in. all textboxes have the properties for increase/decrease to accomadate turned off.
The biggest issue I am having is in printing from the deployed report versus printing while designing. I have adjusted for the glitch in margins for RS2005 and have printed succussfully prior to deployment to adhere to the specific measures for the label, report margins and textbox height and width and blank column spacing.
However, after deploying the report the data spacing seems to be compressed when printed. I am not getting the same measure between data fields as I had when designing the report. The entire printout seems to be slightly compressed.
When printed from design colums 1,3,5, and 7 start respectively at .3125in,2.375in,4.3756in,6.4375in from the edge of the page.
When printed fromt he deployed report columns 1,3,5 and7 start respectively at .3125in,2.3125in,4.28125in,6.28125in.
The progression of compressed measure seems to increase from left to right inthat by the time the report is printed via the deployed report the "Tab" area is a difference of .15625in which when printing for very precise template format this creates a problem. As well as a headache when one thinks the report is correct before deployment.
Transaction Log Shipping Over WAN With Compression
Jan 18, 2006Hi guys,
I have a server in a datacenter (SQL 2005 ent) that collects large quantities of data from our visitors. I need to set up a secondary database in our office (different geographic location) that will server 2 purposes, 1, a backup of the database and 2, allow us to perform complex queries on the data.
There is no updating of the data on the secondary server so no changes need to go back to the primary server. A database in standby mode is fine and users on the secondary server can be disconnected when it's being updated.
I have transaction log shipping working well in a staging environment (LAN). My first question is is there any reason why transaction log shipping would not work over a WAN with a VPN connection?
And my second question is can I compress the trn files for transport over the WAN. If I manually compress the files with winzip they compress by 98%. That translates into a huge saving when I am leasing a line to transport these files.
Thanks in advance
Stephen

What is the recommended way to handle this if the conversions are happening in TSQL?

SQL 2012 :: Is Table Compression Suitable To Reduce I/O
Feb 11, 2015I have huge table, often I need to query the table on the whole; ie., data may required at any part of the table. So I think of to compress the table with the aim of reducing I/O.
1. is that really suitable for this requirement? If So which compression is good (Row or page )?
2. Or is there any other alternate to reduce the I/O (Except Indexing)?
3. Pros and cons ?
Is It OK To Copy Database Backups To Tape Using Compression?
Dec 27, 2006Hi, I back up SQL Server 2000 and SQL server 2005 databases to hard disk using the SQL Server Backup Wizard and maintenance plans. Then, I copy the resulting backups to tape using third party tape backup software and compression by the backup software and hardware. I do not use the SQL Server Agent available for the third party backup software. Is this acceptable, or does the compression performed by the third party backup system introduce opportunities for database corruption or other negative effects?
Thanks

ReportViewer 2008 / 9.0 PDF Export/Render Compression Question
Apr 15, 2008I print 4x1 inch labels, anywhere from a few to a few thousand. It's all done from an asp.net page with a 9.0 report viewer in local processing mode.
108 Labels = 37MB or so.... this is totally unacceptable for something that when zipped becomes 1.3mb.
I thought version 9.0 was supposed to have PDF compression... Is there some kind of setting I'm not seeing any documentation for somwhere? how do i enable it?
This better not just be a server processing mode feature like the print button again... I've already taken plenty of heat from the bosses just for that alone. Try explaining the difference between a local report and a server report to your boss and then try to come up with a real world explanation as to why he can print some reports in some programs and is forced to export and printer them from adobe in other programs... please don't let me die have mercy.
SQL Server Admin 2014 :: DB Growth Report With Compression Turned On?
Apr 14, 2015I got into confusion while working on DB Growth report for 2012 databases which has compression on.I am analyzing the DB Growth based on MSDB..dbo.backupset table which stores the backup information.
But here it gets tricky, In Previous versions we use "backup_size" column to get actual backup size and estimate the db growth based on the previous all backup file info. But now since compression is on in 2012 the "backup_size" colmuns gives a compressed file size(If i am right) so how do you know the actual backup size to estimate the db growth over a period of time??
SQL 2012 :: SSMS Object Explorer Lock Timeout When Running Compression Script
Jan 21, 2015ALTER TABLE [dbo].[TableNameExample] REBUILD PARTITION = ALL
WITH (DATA_COMPRESSION = PAGE)
The table is 110 GB, so will take time to compress. But it is one table in a database with 60 tables. Why would executing this statement, cause lock timeout on Object Explorer in SQL Server Management Studio? Users cannot drill down objects in this database without getting lock timeout.
When I cancel the compression script, users of SSMS can access objects in this database again from the GUI. Why does compressing a specific table affect access to all tables metadata? I cannot find anything on the internet but I am sure this has happened to other people.

Data Reader Or Data Adapter With Data Set?
Dec 4, 2007I have used both data readers and data adapters(with datasets) in the projects that I have worked on. I am trying to get some clarification on when I should be using which one. I think I am doing this correctly but I want to be sure I am developing good habits.
As the name might suggest, it seems like a datareader is for only reading data. I have read that the data adapter and dataset are for a disconnected architecture. Or, that they can be used for this type of set up. I have been using the data adapter and datasets when writing to a database and the datareader when reading from a database.
Is this how these should be used? Is the data reader the best choice for reading data? Am I doing this the optimal way from a performance stand point?
