I have been using enterprise manager to run backups. I backup up all the
db's system and user under one maitenance plan. I have it set to remove the
bakups after 7 days. The backups are removed but not the tranaction log
backups. Why is this and how can I resolve this so I don't have to manaully
delete delete the tranaction log backups.Hi Geroge,
Thanks for posting.
I noticed that you posted another post abouit MSDE backup in newsgroup.
From that post, I noticed that you are using simple recovery mode. If so,
there will be no transaction log be backed up.
Regarding backup plan, please refer to:

Hope this helps.

You say you're backing up ALL databases within a single maintenance
plan? Are any of these databases in Simple recovery mode? If so, then
transaction log backups are not possible for those DB's, and that is
likely causing the transaction log part of your maintenance plan to
fail, preventing it from running the deletion step.
Check the job history and the maintenance plan history for error messages.

Refer to Books Online for more info on recovery models. There's not a
blanket answer to your question, you'll have to decide what is
appropriate for your needs.

Thanks for your reply.
To switch recovery mode, please refer to following article:
<http://msdn.microsoft.com/library/default.asp?url=/library/en-us/adminsql/a
d_bkprst_8ik3.asp>
Actually, MSDE & SQL 2000 is the same by the nature. Therefore, you can
refer to my reply in the "MSDE Backup " Thread. For your convenience, I
paste it here
==================If you perform full backup regularly, you can just restore the latest
backup when disaster occurs.
The transaction log is a serial record of all the transactions that have
been performed against the database since the transaction log was last
backed up. With transaction log backups, you can recover the database to a
specific point in time (for example, prior to entering unwanted data), or
to the point of failure. Check following article:

That all depends on the recovery model that you're using. The
transaction log records everything that happens in the database. Let's
say you delete a million rows from a table, and partway through that
delete operation, it fails. The delete will be rolled back, none of the
records will be deleted. In order to perform that rollback, SQL has to
record somewhere what records it's deleting - that's what the
transaction log is used for. The transaction log will need to be large
enough to hold this entire transaction. If the delete is successful,
the transaction is committed, and the events recorded in the transaction
log are flagged as committed.
In SIMPLE mode, SQL will issue periodic "checkpoint" instructions that
will flush out those committed events, and the space that was previously
used for them will be available for future transactions to use. The
transaction log will not shrink at this point, it will remain the same
physical size. Once the committed events have been flushed, they are
permanently written to the database, and the only way to "undo" them is
to restore from a full backup taken prior to the delete, probably the
backup from the night before.
In FULL or BULK-LOGGED modes, these committed events are not
automatically flushed out of the transaction log. They are flushed when
you issue a BACKUP LOG command. This gives you the ability to recover
the database to virtually any point in time. For sake of example, let's
assume you're taking transaction log backups every 5 minutes. You
delete the million rows, and an hour later, decide that you need those
rows back. You simply restore the previous full backup, and then
restore each transaction log backup up to the point where you issued the
delete. You lose an hour's worth of work instead of a full day.

In Simple mode, committed transactions are automatically purged from the
log file by SQL's checkpointing process, so there's nothing in the log
for you to back up.

http://www.realsqlguy.com|||Correct me if I'm wrong on this one concerning recover modes. In sim[ple
recovery mode the tranactions are recorded in the log but as soon as they are
applied to the databse sql purges them from the log so in essece the log is
empty in this recovery mode.
If I'm running simple recovery then I should change the maitenace plan
backup configuration not to backup the tranaction logs correct?
Is it alright to have one maintenace plan to backup all the db's both system
and user?

Correct. You cannot run a transaction log backup against a Simple mode
database. However, you should consider if the risk of data loss, and
decide if Simple mode is right for your needs.

tranaction backups was becuase I was running backups on db's that were in
simple recovery mode. This is not the case. I have some db's in simple and
some in full recovery mode. The one's in simple recovery mode are fine and
do not have a tranaction log backup created. Its the four pr have db's that
are in full recovery mode. The tranaction logs backups are not being deleted
like the bak files from the backup directory. What can be causing this and
how cna I resolve this?

little bit daft and doesn't remove old tlog backups for the ones in full mode.

The problem is that you're doing all of this from ONE maintenance plan,
and have told the maintenance plan to do transaction log backups of ALL
your databases. When it attempts to do that, it fails on the ones that
are in Simple mode, and never gets to the cleanup step where it deletes
the old files.
Create two seperate maintenance plans, one for the Simple mode
databases, one for the others. OR, better yet, dump the maintenance
plan altogether and use scripts to perform these tasks. Here is one:
