Maitenance plans and noskip

I am using SQL Server 2005. I have a Backup Database task which I use
to back up to a single backup device. I want to set a retention time
of 3 days and have old backups overwritten. This seems to be the WITH
INIT, NOSKIP problem. However using the wizard there doesn't seem to
be the possibility of doing this. I find it hard to believe though
that anyone would write a wizard which didn't offer this feature.
Is there any way to backup with NOSKIP or failing that alter the SQL
genereated by the wizard.
For info, here's the first few SQL statements from the wizard!
BACKUP DATABASE [master] TO [All299LocalDatabases] WITH RETAINDAYS
=
3, NOFORMAT, INIT, NAME = N'master_backup_20070802123131', SKIP,
REWIND, NOUNLOAD, STATS = 10
GO
BACKUP DATABASE [model] TO [All299LocalDatabases] WITH RETAINDAYS
=
3, NOFORMAT, NOINIT, NAME = N'model_backup_20070802123131', SKIP,
REWIND, NOUNLOAD, STATS = 10
GO
BACKUP DATABASE [msdb] TO [All299LocalDatabases] WITH RETAINDAYS =
3, NOFORMAT, NOINIT, NAME = N'msdb_backup_20070802123132', SKIP,
REWIND, NOUNLOAD, STATS = 10
GO
BACKUP DATABASE [ReportServer] TO [All299LocalDatabases] WITH
RETAINDAYS = 3, NOFORMAT, NOINIT, NAME =
N'ReportServer_backup_20070802123132', SKIP, REWIND, NOUNLOAD, STATS
= 10
GO
etcThere's no way in SQL Server to backup to a single backup device and overwri
te "only the oldest"
backups. Either you overwrite everything, or you append. Period.
Now, I understand that the interaction between INIT/NOINIT and SKIP/NOSKIP c
an be confusing, and
that it probably why there's a section in Books Online titled "Interaction o
f SKIP, NOSKIP, INIT,
and NOINIT" (in the BACKUP topic). Bu, as mentioned before, SQL Server eithe
r overwrites everything
or not at all. This is how the engine work, so it doesn't relate to the main
tenance wizard.
Personally,. I don't use SKIP/NOSKIP at all, as I don't find those options a
dding anything to
INIT/NOINIT.

option either in the Wizard. You only have the option that it either
expires or it doesn't as whatever you do it always puts in SKIP into
the SQL. The only way you seem to be able to backup without having old
backups is to backup to individual files rather than using a backup
device as I am.

s overwrite?
In my wizard (I'm on sp2, there has been improvements here...), I see an opt
ion "If backup files
exists:" and I select "Overwrite".
Here are the backup commands executed, as catched by Profiler:
BACKUP DATABASE [master] TO [MyDevice] WITH NOFORMAT, INIT, NAME =
N'master_backup_20070802151715', SKIP, REWIND, NOUNLOAD, STATS = 10
BACKUP DATABASE [model] TO [MyDevice] WITH NOFORMAT, NOINIT, NAME
=
N'model_backup_20070802151715', SKIP, REWIND, NOUNLOAD, STATS = 10
As you see, it does INIT for the first backup and NOINIT for the following b
ackups. Is above what
you want, ir are you saying that there's some problem with the TSQL above?

However, the answer to my problems was to use a one-off backup file
rather than have a pre-allocated backup device. I could then move to
the file to somewhere else and start afresh with a new file the next
day. Thanks for the help anyway.
