Backup database

I have couple of questions about backing up a database

1. How to create a backup file (using script) which only contain the data of a specific time range?

2. How to restore the database with serval backup files; for example, I got backup for june and july, how can I restore them into one mdf file which contains the data of both june and july.

3. how can I backup a database to a remote computer?

Thanks for your concern on my Qestions

I do strongly suggest you to start reading about backup functionality in SQL Server starting from this overview, as it seems you really did not understand what a backup is

3. how can I backup a database to a remote computer?

this can be easely done, even if not directly recommended (at least not by me).. usually you perform a "local" backup and, later, you push or pull that backup remotely via scheduled tasks, or scripts or the like, in order not to load to much the SQL Server service with tasks not directly related to it's main activity.. anyway, you have to grant the account running SQL Server service enougth NTFS permissions on the remote share you are dealing with... in our case, SQLExpress usually runs under Local System, Local Service or Network Service builtin accounts, and you can not add remote permissions to these ones.. you have to define a domain account to use for the service and grant this one appropriate permissions (AD and NTFS) to complete the task on the remote share..

In addition to Andrea, the transfer to normal UNC paths are not reliable, leading to the problem that the transfer could stop somewhere in the middle of the process, unless you use something like a SAN or NAS storage which has a much more reliable way for tranferring. Use the local copy to copy the files (e.g. usign Xcopy with a restartable copy process) to make sure the file was really copied).
