Examples
Intel recommends you use Streamlined backup as your first line of backup
protection, and use
Custom backups to augment Streamlined backup. Here are some ways to use
Streamlined,
Custom, and Tape-to-go backups:
* You want extra protection for mission-critical servers, so you want
only those servers backed up fully every day. Let Streamlined back
up all file servers and workstations on your network each day and
create an additional Custom backup for each file server. (To save
tapes, the Streamlined default is to back up all files [full] just
once per week and only changes the rest of the week.)
Tip: Use the Copy Job... command in the "Job Schedule" screen to
create a number of similar Custom backups quickly.
Don't worry about Streamlined and Custom backups interfering with
one another. Streamlined and Custom each use a different
mechanism to determine which files to backup: Streamlined uses a
create/modify date, while Custom uses a file attribute called the
"archive flag."
* You set up a remote sales office with its own StorageExpress
system. To replicate your local file server at the remote site,
create a Tape-to-go for the file server and send the tape to the
remote office. The remote office should use its own StorageExpress
system to merge the tape, then restore the data to the remote
office's file server.
* You want full backups for all of your servers every night. Even in
this scenario, Streamlined backup offers advantages that Custom
backups don't. Change Streamlined backup's default schedule to do
full backups every night. Streamlined will still take care of tape
naming and tape rotation for you.
