I would like to implement the Backup strategy that is documented in SQL 2005
BOL : "Differential Database Backups Strategy (Full Recovery Model)".
Let's say that I would like to perform a full database backup every hour,
log backups every minutes, differential database backup every 10 minutes. I
would like this to occur every hour every day.
I can't figure out how to sequence and schedule this strategy. In a
maintenance plan, all tasks are running without waiting the time required.
Any help appreciated.Hi Olivier
One way to do this would be to only carry out the task if there is no
exceptions for the other jobs by looking at sysjobhistory.

1) Full database backup Occurs every day every 1 hour(s) between 00:00:00
and 23:59:59. Schedule will be used starting on 18/10/2006.
2) Log Backup Occurs every day every 1 minute(s) between 00:00:01 and
23:59:59. Schedule will be used starting on 18/10/2006.
3) Differential Database Backup Occurs every day every 10 minute(s) between
00:10:00 and 23:59:59. Schedule will be used starting on 18/10/2006.
But one problem remains : Differential datatabase backup and transaction log
backup run at the same time at : hour + 0, Hour +10, Hour +20, Hour+30,
Hour+40, Hour+50. But maybe this is not a problem at all ?

What I feel is that taking full backup every hour you are creating
overhead on the system.
You should take full backup once in a day , differential backup after
some hours and logbackup at some mintues interval.
For high availability of data you should look at replication , log
shipping or database mirroring.

There could be up to 120000 unique mailboxes. Each client connects every
minute, download the mailbox content, and delete message(s). Unless new
messages comes in and the POP server is unavailable, all mailboxes are
empty, which means that the database size is very small, unless empty.

A full/differential backup can be made while your SQL Server is in use.
This is considered a "fuzzy" backup?that is, it is not an exact image of
the state of the database at any particular point in time. The backup
threads just copy extents, and if other processes need to make changes to
those extents while the backup is in progress, they can do so.
On the other hand, transaction log backup back up transaction log other
than the data itself. A log backup copies all the log records that have
been written to the transaction log since the last full or log backup was
made.
Therefore, I think this shall not be a problem even if differential/log
back up starts at the exact same time. Actually, there shall be one backup
starts first. For example, if transaction log backup starts first, after
the restoration of the differetial backup, you shall restore the
transaction log backup at next minute.
I think the important thing is get the proper sequence of the backup files
so that you may be able to restore it properly when issues occurs. Also,
since you have so many backup files, mangement of their store shall be
considered.
You may want to test your plan and see if there is any issues when
restoring the backups.
If anything is unclear or you have further questions on the issue, please
feel free to let's know. Thank you.

In this strategy, backup files older than one hour could be deleted because
I have a full database backup every hour. The number of files to manage is
small.
The main goal here is to be able to restart as quickly as possible in the
event of a disk failure. I already know that the the tail of the transaction
log should be backuped immediately in this cas before the restore process.
At this time I have choosen to put the database data file on a RAID 0 array,
while backup and transaction log files are located on a RAID1 array.

I have a full and differential backups with script listed
below from SQL Server 2000 BOL. I was able to create the
full backup and the differential backups with the script
listed below without a problem. I trying to restore the
full and differential from SQL Server 2000 Enterprise
Manager GUI. First I restored the full back from the SQL
Server 2000 Enterprise Manager Restore GUI without a
problem.
Next I tried to restore the differential backup from the
SQL Server 2000 Enterprise Manager GUI using the restore
type as differential. I received the following error:
The preceding restore operation did not specify WITH
NORECOVERY or WITH STANDBY, Restart the restore sequence,
specifying WITH NORECOVERY or WITH STANDBY for all but
the final step. RESTORE DATABASE is terminating
abnormally.
Is it possible to restore a full/differential backup from
the SQL Server 2000 Enterprise Manager Restore GUI?
Please help me resolve this problem.
Thanks,
Jan
Hi,
Check the "Leave database nonoperational but able to restore additional
transaction logs." or "Leave database read-only and able to restore
additional transaction logs." radio button on the Options tab before start
the restore from full backup.
This operation create restore script with "WIH NORECOWERY" or "WITH STANDBY"
clause, and you can restore from differential backup as need.
