I have a sQL 2005 database that currently is not being backed up at all. I need to implement a backup strategy but I am not sure how to do so. About 1% of the database is updated each day and so I would need to have my back strategy run at least every 30 minutes.
It's difficult to give a suggestion based on your description but I'd recommend reviewing this backup overview (especially if you're in charge of coming up with the backup strategy for a production database):

How you arrived at 1% updated per day, I'm not sure.. but if this is really the case then I'd give special attention to the differential backup options.
Try to use sqlbackupandftp it is free for up to 2 databases a day. will enable easy backups to mail ftp and dropbox.

In Sql server 2000 version I found there is daily full backups are going on for all databaeses at one particular time.
But I didn't found any maintainance plan or any job or any windows task schedule to take the backups.
Here my point is how the backups are going on automatically? I want to find out how?
Please help
I'm using Microsoft SQL server and storing lot of data daily. I'm taking full backup daily which takes more than 5 hours to complete. Is there any idea to complete my backup process within a hour ? An alternative things to do?
Daily differential backup (only changes will be backed up) and CloudBerry software will make you deal:)
Definitely consider taking differential backups. Depending on how much data is changing you may be able to take differential backups every hour or so, giving you a quick way to restore the hourly backup if needed. Perhaps complete a full backup once a week or every few days.
There are several considerations and I suggest you research it well to see if it will meet your specific needs, for example (source):
If your databases are small or compress effectively enough so that your full and transaction log backups fall within storage and SLA limits, differential backups are unnecessary.
If your databases change a lot between backups, you might as well perform full backups.
If the changes to your database are few and the transaction log backups would take longer to restore than the differential backups, using differential backups might make sense and are worth investigating.
Other things to consider:
Are you currently taking transaction log backups? Should you be? What recovery model are you using?
If you decide to do differential backups, be aware of things such as the "Copy only backup" option in SQL Server Management Studio. These have implications for restoring data in a disaster recovery situation.
In essence, you should educate yourself on SQL Server backup and restore before you make any changes.
To improve the situation and to speed the backup you may consider differential and transaction log backups. You can do it through the studio, but to schedule it you will have to refer to a 3-rd party tool like CloudBerry.
The alternate to taking full backups daily is taking incremental/ progressive incremental or reverse incremental backups.
An incremental backup copies the changes only from the last successful backups.
Progressive incremental has only on one full backup copy for the servers and takes incremental backups for the rest of cycle.
Reverse incremental supported by Veeam and DPM has its own mechanism to backup and store only incremental copies from the server, and store each copy as a full copy which allows quick restoration in case of disasters.
To configure this kind of backups, you can go for any enterprise level backup tool, but if you focus on cost effectiveness I would recommend Cloudberry backup.
I tried CloudBerry Cross-Platform Cloud Backup which provides a simple GUI to manage backup and restores and cloud storage account comes bundled with the software.You can also use the cloudberry explorer to view, move and manage your data on the cloud storage account.
It also provides enterprise backup features like job scheduling, CLI, compression and encryption.
I manage a web application for a client with the following specs:
ASP.net 3.5 running on a Virtual Windows 2003 Web Server
SQL Server Standard hosting the database
Database current size of 6Gb, with 1Gb/month growth rate
One single table is responsible for 98% of the size, holds the most critical data for the client
Log is not kept for this big table, only selects are done in this table
50 Gb FTP space avaiable for backup
Considering this scenario, what would be the best strategy for a SQL Backup and what tool would be best suited for this task (commercial applications included, client can pay for the license fee)?
Here is the strategy we use for CodePlex.com:
All SQL servers run with a peer server using SQL mirroring
Weekly full backup (stored on separate drive from databases)
Daily differential backup (stored on separate drive from databases)
Transaction log backup every 5 minutes (stored on separate drive from databases)
Daily tape backup
Tape backups taken offsite weekly
Also very important test your backups! Studies have shown that over 30% of untested backup procedures are flawed. Here is our backup testing strategy:
Every 30 minutes verify the full backup file exists (using scheduled task)
Every 30 minutes verify the differential backup file exists (using scheduled task)
Every 30 minutes verify the transaction log backup file exists (using scheduled task)
Every 30 minutes verify the database mirroring is configured (using scheduled task)
Every day, do a test restore of the full+differential backup and report the table row counts (using scheduled task)
Once a month do a test restore of the most recent tape backup and verify the data
It depends how critical is the data. Here is however how I i'd do it.
1. Run a full backup every day.
2. Run a differential backup every 4 hours.
3. Run a transactional log backup every 15 minutes
4. Keep a copy at the site and move a copy off the site as well as soon as the backup is done.
The database is not too big, and this is easily doable.
Use a third party tool like Redgate SQL Backup and it will automatically compress and encrypt the database backup for you. I have used it extensively and am a big fan.
Additionally if you another site available, and the data is very critical, you might want to think about setting up log shipping as well.
This is a VPC? Can you install apps?
http://www.jungledisk.com/
That's what we use - make a sql job that pushes out a backup every day, then use that service to push a copy back to Amazons S3 service. If not maybe you could have a local app that pulls the backup to a machine then pushes it /w S3 webservice, or still using Jungledisk.
This is important! If your app goes down it hurts! Also make sure you backup your deployed app and resources stored there... i.e. uploaded content to your apps storage directory.
I was supposed to type in my answer to your question but I realized there are lots of far greater resources somewhere like this article in SQLServerCentral.com. You can also find lots of "Best Practices on Backup" like this one.
You might also want to take into consideration how much data you can afford to lose and how long it will take you to restore the database. Your client may decide that they never want to lose more than 15 minutes of data ever, or they may decide that losing up to a days worth of data is okay with them.
I want to implement an automated backup system for my site's SQL Server 2005 DB that will backup nightly to Amazon's S3 service. But since S3 charges both for space and bandwidth used, I would like to minimize the size of the files that I transfer in. What is the best way to achieve this?
I should clarify that I'm not really talking so much about compression, which is pretty straightforward, but concerning backup strategies like whether to do differential backups all the time, whether I need to copy transaction logs, etc.
Differential backups will be smaller than full backups, of course. However, you should consider the restoration side as well. You'll need your last full backup as well as your differentials to perform the restore which can add up to a lot of bandwidth/transfer time for a restore. One option is to perform a full backup weekly and do differentials daily (or a similar type of schedule).
As for transaction logs, it depends on what granularity you're looking for in restoring your data. If restoring to the last full or differential backup is sufficient, then you don't need to worry about taking transaction log backups. If that's not the case, then transaction log backups will be necessary.
Either use a commercial product do compress the backups like Red Gate Backup Pro or just zip-compress it after you're done.
Write a .batch script or powershell script that will find the file/s created in the past day and zip them up. Then FTP or whatever you have to do.
A powershell example that I just came across.
Warm Standby SQL Server/Web Server
This question might fall into the IT category but as the lead developer I must come up with a solution to integration as well as pure software issues.
We just moved our web server off site and now I would like to keep a warm standby of both the website and database (SQL 2005) on site.
What are the best practices for going about doing this with the following environment?
Offsite: our website and database (SQL 2005) are on one Windows 2003 server. There is a firewall in front of the server which makes
replication or database mirroring not an option. A vpn is also not an option.
My thoughts as a developer were to write a service which runs at the remote site to zip up and ftp the database backup to an ftp server
on site. Then another process would unzip the backup and restore it to the warm standby database here.
I assume I could do this with the web site as well.
I would be open to all ideas including third party solutions.
If you want a remote standby you probably want to look into a log shipping solution.
This article may help you out. In the past I had to develop one of these solutions for the exact same problem, writing it from scratch is not too hard. The advantage you get with log shipping is that you have the ability to restore to any point in time and you avoid shipping these big heavy full backups around and instead ship light transaction log backups, and occasionally a big backup.
You have to keep in mind that transaction log backups are useless without having both the entire sequence of transaction log backups and a full backup.
You have exactly the right idea. You could maybe write a script that would insert the names of the files that you moved into a table that your warm server could read. Your job could then just poll this table at intervals and not worry about timing.
Forget about that - just found this. Sounds like what you are setting out to do.

I've heard good things about Syncback:
http://www.2brightsparks.com/syncback/sbpro-features.html
Thanks for the link to the article sambo99. Transaction log shipping was my original idea, but I dismissed it because the servers are not in the same domain not even in the same time zone. My only method of moving the files from point A to point B is via FTP. I am going to experiment with just shipping the transaction logs. And see if there is a way to fire off a restore job at given intervals.
www.FolderShare.com is a good tool from Microsoft. You could log ship to a local directory and then synchronize the directory to any other machine. You could also syncrhronize the website folders as well.
"Set it and forget it" type solution. Setup your SQL jobs to clear older files and you'll never have to edit anything after the initial install.
FolderShare (free, in beta) is currently limited to 10,000 files per library.
For all interested the following question also ties into my overall plan to implement log shipping:
