I got this situation where my network admin observerd that there is a high network utilization between 2 nodes in our AG (the primary node & the DR site, 2 separate locations of course); then he advised to compress the data transfer between those 2 nodes as the previous DBA already did that before!
Ok, I have no clue about this, so decided to google it, got nothing. My backup is already compressed through some third party app (just in case if that matters to the subject).
I work with MSDE, now the dimensions are of 2 GB....I have deleted many pages, is possible to compress the database?
Thanks in advanced
i have a table that is often deleted from and added to.
i noticed that it gets realy slow -
is there a way to compress a table? (there must be even in access you can compact and repair)
is there sql code that I can call from my code after doing a lot of deleting to speak this up.
Please advise.
I can't "point in time restore" a test DB if I had only a Full DB Backup (with overwrite option).
Example
12:00 Fullbackup new (overwrite)
12:01 update any rows
12:02 update any rows
12:03 delete any rows
12:05 Transaction Log backup (overwrite)
RESTORE: We can't set "point in Time" to 12:01 od 12:02 ???
why
Hi
1. could any one explain point in time recovery.
2. Problem we had was the database froze 'inload' while doing transaction restore. Is there any way to recover this

My database is in full recovery mode. When I have created some full backups of the database, I would like try to point in time restore. Unfortunately, this option is greyed out on the restore screen. What have I done wrong?

I have a SQLServer 2005 database running in Windows 2003 Advanced Server environment. I want to restore from the backup to 2 days back point in time. I am using the Microsoft SQLServer Managment Studio. After I pick the file and specify the time I keep getting the error:
System.Data.SqlClient.SqlError: RESTORE cannot process database 'DBNAME' because it is in use by this session. It is recommended that the master database be used when performing this operation. (Microsoft.SqlServer.Smo)
I did a server reboot to clear off any hanging session.Stil I am getting the message. Please suggest.

I have full backup of database at 13:00and another full backup at 17:00.I've made backup of transaction log at 17:05When I try to restore database to state at15:10 (point in time) , the dialogue in Enterprise Managersays that only time after 17:05 is valid.It seems to me that I've done something wrong at 17:05 while takingtrans. log backup.But, again, if I have full backups at 13:00 and 17:00 restoringdatabase to point in time at 15:10 should be possible ?!Any help is appreciated.Pagus

We moved a 2000 database to another platform by restoring the database. It took a lot longer than I expected. Would it take less time to restore it a second time to the same target database since the allocations are already there?
Thanks
I was planning on running a service where thousands of text messages are stored. Obviously I'd want to make the most of my DB space, and was wondering if there's some way for SQL to compress text down to the smallest space possible. If not, is there some kind of ASP component I could download to do this? Failing that, I could always write a simple one, which takes the most common letter combinations, and shortens them down to a single character.
Any advice?

View 3 Replies View RelatedI do hourly transaction log backups at 9,10, 11 etc...
When I restore from a 9:00 backup I clearly see changes that I made after 9:00 am!!!
I then noticed when I go to my scheduled backups that a 10 am backup was indeed done
but in the "restore from device" tab it says the last backup was at 9 am.
Apparently it is not showing the actual latest backup that was done. This explains why
when restoring from a 9am backup I am seeing changes after 9, because in reality
I am restoring from a 10 am backup!
Is this a bug? I am running on 6.5 sp 5a.
thanks in advance....Mary
Hello,
I have lost a table's contents and need to restore them urgently. I backed up the database. I selected the backup set in order to restore it, but the "Point in time restore " was disabled and I couldn't select it to set the time to which to restore.Could anyone tell me the reason behing that?
Another interesting thing is that when I backup a database, I only have two options for backing it up,
1. database complete
2. database differential
Thanks a lot,
Joe
I have full Recovery mode.
I just accidently deleted a handful of records out of a table about 10 minutes ago. My last backup was last night.
Can I go back 10 minutes ago for a specific table? If so how... DO I need to backup now, then use the trans-logs to recover up to a specific point?
Thanks!!
hi all!
can you help me, in which case will i need to Specify a Point in Time, when restoring a database?
for newbee like me, it looks like it's better to restore without Specifying a Point in Time, because i will restore my data, without headache.
can you give me some sort of example when and why to specifying a point in time?
thank you 1000x in advance!
In the hereunder written message I talk about point in time restore.It is now based upon the fact that there are no hardware problems or what soever.I just would like to roll back to a situation of some time (minutes, hoursor what ever) ago.Used to the ingres database a point in time restore can take place UP toany, any, any time since the last FULL backup. (any time up to now !!!)I can't understand why a point in time restore can only be done based upontransaction log backups. The current transaction log is also available in myopinion. (Turn off the power, turn on the power and you will notice that theautomatic recovery is based upon this transaction log file; so in that casethis file is used)That's what my question is about. Is it correct that a point in time restorein a SQL server environment can only be done up to the last transaction logbackup.ByeArno de Jong,The Netherlands.

I don't see a "general discussion" thread and this is the closest i think.
I just have a general question: if my backup window is from 8am to 10am, and i do a restore within that backup window, what will happen? assuming we're talking only of a single database, ACME.
I'm comparing because with Oracle RMAN, it pukes when i do a restore while the backup is going on. it would complain of unable to find some archive logs.

How could i restore a filegroup to a certain point of time (not to apply all
transaction log up to the latest one) ??
Greetings, All -
Is it possible to restore to a point in time without a preexisting full backup? The situation is this:
I have a table in the DB from which an unknown number of records were accidentally deleted. The table in questio has about 2 million records; the user ran a query to delete all records from the table by accident, and cancelled the query after about 3 seconds.
The DB recovery mode is full, so I should be able to do a point in time restore to go back to just before the deletion, but unfortunately, the DB has never been backed up, so I have no backup to work from.
The DB has not been used since the incident, and is otherwise operational, but I need to recover these records if at all possible. All the instructions I've seen for this involve restoring from a full backup first, then restoring the log backup second. Is there any way for me to accomplish the same task?

Here is data I am working with:
CREATE TABLE HISTORY(CUSTOMER VARCHAR(10), PLANNBR VARCHAR(10), SUBPLAN VARCHAR(3),
STARTDATE DATETIME, ENDDATE DATETIME, HISTORYMONTH VARCHAR(6))
INSERT INTO HISTORY(CUSTOMER, PLANNBR, SUBPLAN, STARTDATE, ENDDATE) VALUES('9111111', 'H1111LAC', '006', '2014-01-01', '2014-05-31', '201401')
INSERT INTO HISTORY(CUSTOMER, PLANNBR, SUBPLAN, STARTDATE, ENDDATE) VALUES('9111111','H1111LAC', '006', '2014-01-01', '2014-05-31', '201402')
[code]...
I need to compress these segments into records which will look like this. The HistoryMonth column is not used to make the final determination of records to keep.

I have a SQL 2012 enterprise server, and I'm using Commvault as my backups. So commvault can restore a .bak file to my server, but it cannot use sql compression on the file apparently. So what would be a 150GB .bak backup file is now 600GB. I have to manually upload these files to an auditing firm on an sftp server and the transfer times are now huge.
Is there a way to use something in sql to compress this already existing .bak file down?
Is there any improvments in SQL 2008 backup methods such as spliting backup files in manageable size(s), compress the backups and/or improving the speed of backup?
Though there are "commercial" tools available, it would be nicer if Microsoft SQL team can incorporate some core needed features in these areas for Small/Medium size businesses.
This is not a question but a suggesstion.
Thanks
Hey everyone,
I have an issue where i am sending out files with 30,000+ lines and they are reaching the 11mb, 12mb in size.
This is becoming and issue for us, as we are only allowed to email up to 10mb in size.
I have tried reducing all spaces in the data, removing any graphics etc from the report , but still the excel file is over 11mb. One thing i did find was that, if i export it to excel, then open the file and save as a different file name the file size drops 50% !!
I was wondering if anyone has been able to zip/compress the exported file before it gets emailed?
It would be a great feature for MS to include in the next service pack.. Take advantage of the built in Zip support in Windows..
Look forward to hearing any suggestions that the community may have,
Thanks

1. SQL 2008 R2
2. Maintenance Plan -
a. Daily, Weekly, Monthly schedule
b. Full Back Up - All Database, To Disk, for every database and Disk:DirectorySubDirectory*.bak Compress backup
3. SQL Agent Job
a. Runs the Sub_Plan's at scheduled time I've allocated for each Maintenance Plan.
4. These creates Multiple .bak for all database's that list in the directory.
How can I zip them into a compressed Directory.
I have a backup mainentance plan that does a full backup daily at 03:00am and then 2 minute transaction log backups throughout the day to a raided hard drive (It is set to overwrite after 2 weeks), When i go into enterprise manager and select the database to restore it just seems to take too long to read the backup history in. Can this time be reduced as i need to be able to restore the database A.S.A.P but still need a point in time restore to within 2 minutes of going down??
Thanks
Our backup system has worked ok for us to date. We can restore back to either full saves or up to a certain log (we take log backups on the hour). We've never had to, but wanted to test restoring to a point-in-time with the backup data.
What the system does is generates .mdf and .ldf files, which is essentially a full backup say in the middle of the night. It then creates .bak files for the log backups based on the backup set you want to restore.
I can detach the database and apply the .mdf and .ldf and re-attach the database, but to apply the .bak files I need to get the database into a (recovering) state. I can't seem to do that. Otherwise when I try to apply the .bak files the system says: The log or differential backup cannot be restored because no files are ready to rollforward.
How to apply a .mdf and then apply the .bak files?
Can I use a full and differential backup to restore to a point of time?
Or I have to use full and transaction log backups in order to do a point of time restore?
I found today when I tried to restore a db from another database at the point of time for example 3:10 pm,
SSMS automatically select the full backup + the transaction backup that is done at 3:00 pm, but not select full + the differential backup I did at 3:12pm.
So I lost those records entered after 3:00pm.
I supposed it should use the differential backup and restore to 3:10. but it didn't.
