What is the percentage of FREE disk space that is needed for a backup? I have backups that are failing with no disk space errors. But there is enough disk. Does SQL Server need a percentage of free space all the time?
Thanks

does anyone know if tempdb can be physically moved to a different partition on a disk drive on SQL Server 7.0? Since it can't be backed up I'm hesitant to use the sp_detach/sp_attach procedure because I don't want to crash it. If nothing else is available, I can attempt moving it this way at the end of the day and then just reboot to get tempdb back up again if the server fails, but I'd really appreciate a suggestion from someone who has more know-how than I do about system table operations. Thanks again

I have to find free disc space in a drive from SQL Query and i am using MSSQL200. Does any body know the command for the same.
Also if i want to find hard disk space of a different machine on network, it is possible to get the data??
Also can i get the CPU/Memory usage data of our machine by some SQL/C++ commands??
Please let me know if u know any of the answer...
thanks

Hello
I have a script which checks the disk space and when it falls a certain size , it mails the dba mail box.
I would like to know how I can change it , as a percentage calculation.
For example when the free space is less than 20% of the total space on the drive I should be receiving a mail.
The script I have is :
declare @MB_Free int
create table #FreeSpace(
Drive char(1),
MB_Free int)
insert into #FreeSpace exec xp_fixeddrives
-- Free Space on F drive Less than Threshold
if @MB_Free < 4096
exec master.dbo.xp_sendmail
@recipients ='dvaddi@domain.edu',
@subject ='SERVER X - Fresh Space Issue on D Drive',
@message = 'Free space on D Drive
has dropped below 2 gig'
drop table #freespace
Thanks
Hello
I have got a script which checks the percentage of free space on the drivers of the servers and mails the DBA when it falls below a certain percentage , which can be set according to our requirements.
But I am getting blank emails even when , there is no issue of low free space.
Please help me out.

Quick question- how much disk space is required on the subscriber to initialize a subscription (transactional replication) – does it have to copy the snapshot files (e.g. the bcp files etc) from the distributor, and then initialize the subscriber from this, or does it do this over the network?
Does it differ depending on whether it is push or pull?
Say I have a 10 GB snapshot on the distributor with a push subscription to the subscriber. Do I need 20 GB free on the subscriber? E.g. 10 GB to receive the snapshot files + 10 GB for the subscriber DB? Or just 10 GB for the subscriber DB which is initialized from the snapshot files over the network?
Thanks in advance for any help with this.
Good morning,
We get frequent (1 out of 3) "sqlmaint.exe failed" errors during backups for one of our larger databases (40GB). So i removed the maintenance plan and put in a custom backup job to get a better error msg in the log:
BackupMedium::ReportIoError: write failure on backup device 'F:MSSQLmydb_2008_1_3_21_45.BAK'. Operating system error 112(There is not enough space on the disk.).
However, we have PLENTY of space on disk:
LOG DISK - NTFS - used space = 2GB, free space = 81GB
BACKUP DISK - NTFS - used space = 29GB, free space = 82GB
So even if it doubled in size, there would still be 50GB free.
Any ideas?
Thanks!!
I have a SQL Server 2012 DB in Full recovery mode that has never had a TLOG backup. the log is huge 200+GB.
I tried doing a transaction log backup but there is not enough space on the Disk.
How can I reclaim this log space in SQL Server 2012?
wmic logicaldisk where "DeviceID='C:'" get FreeSpace /format:value
FreeSpace=231379468288
Dear friends
I need to report the amount of free space in each datafile of a database.
I have tried sys.dm_db_file_space_usage , but the documentation says that it only works for the TempDB.
Please help.

I am new to mssql server. There is a table on one of my databases that occupies a lot of space. And the space usage is as follows: (all values in KB)
reserved: 42329064
data: 16272288
index: 26050032
unused: 6744
This table takes up almost 80% of my database size, and the information is this table just captures the time spent by a user on the website(not very critical data)
I would like to know how to delete the entire index (which is what is occupying most space) to free up disk space. the index is a clustered index.
Hi,
I have a 250 GB database and not much space left on the disk drive. I want to run SQLMAINT to do optimization and integrity checks on this db. My question is : How much work space does SQLMAINT need to perform these tasks?.
Thanks in advance for your help.

How do we identify the total disk space of a SQL Server Remotely. The procedure xp_fixeddrives gives the available free space .. but I would like to know the total disk capacity .. Any pointers?
Thanks,
Deepti
As a normal sql user we are not able to get the disk space information by
executing 'xp_fixeddrive' extended stored procedure.
We are able to get the result using sa user and windows authenticated user.
Any help will be appreciated.
I would be able to determine how much hard disk space is available on the Server with a SQL Query, and from an other computer on the LAN.
How can I do something?
Thanks for your help.
My SQL server disk space is getting close to full capacity which is causing certain reports that we run via the SQL server to time out because I don't think there is enough space on the server.
Any tips on cleaning out a SQL server? Are there any folders that can absolutely be deleted to clear space? I know on a local computer that the %temp% folder can be cleaned out. I know when dealing with servers you do not want to make to many changes because it can cause major problems down the road.
Hi,
The SQL Server Database hangs overnight and also consumes high disk space on one of our servers. This has been recurring for quite a few weeks and occurs daily.
Can somebody assist me in trouble-shooting the same

Hi ,

Thanks

I'm trying to determine how much space I would need for my data drive and log file drive to do index rebuild. I have a database which is 100gb, it is in simple recovery mode. let me know what to have a look at to determine how much space.

Hi All,
I was wondering if anybody has the script to view the free disc space. Currently I am using xp_fixeddrives stored procedure, but it is undocumented and might not be supported in SQL Server 2005.
Thanks.
I would like to know how to determine how big log and data space is, and how much of this space is free. I would like to create a script to warn me when less than 20% free space is left in log as well as data.

I've gone through the forum and have seen several others with a similar situation. I recently noticed my .mdf file grew to 200GB yet the data in the file is only about 40GB. I run sp_spaceused and get the following: database_size = 176GB, unallocated space = 134GB, reserved = 43GB, data = 17GB, index_size = 19GB, unused = 6GB.
I've tried "dbcc shrinkdatabase (mydb, truncateonly)", tried restarting server, tried running a maintenance plan including a reindex of the database, and I don't know what to do next.
Does anyone know how to free up this space?
Hi:
How can i get the Total and Free space of my filegroups, do you have some script for that?
Thnaks :eek:
Hi,
While I am importing few data to my SQL Server (2000) database, the free space is gettig increased in GBs. The database's File Growth is 1 MB (same for both Data Files and Transaction Files). The same database I restored on another PC and did the same process, it is working fine as there is no enormous growth in Free Space.
Any idea why this is

I was just reading a doc on SQL , that said that to free up the unused space from the DB , you should use the shrinkdatabase DBCC commnad. ....
I want to knw how to determine how much free unused space is there in a DB
