Use the Continuous Protection panel
to set the maximum space on local storage for backup copies and the
maximum versions of backup copies on local storage.
How many versions to keep field
Tivoli® Storage Manager FastBack
for Workstations can
save more than one backup version of each file. When you restore a
file, you can choose which version of the file you want to restore.
When the configured number of versions is reached, older versions
of a file are deleted. Keeping more versions requires more local storage
space, but allows you more choices when restoring a file.
Maximum space for backups field
Specify
how much space to use for all backup copies on local storage. When
the storage area becomes full, older versions of files are deleted
until the storage area is at about 80 percent of the configured maximum.
If, after deleting all versioned backup copies, local storage space
is still insufficient, Tivoli Storage Manager FastBack
for Workstations will
delete the oldest non-versioned files.
Note: No warning message
displays when the maximum space is reached.
The default space
for local backups is 500 MB.
Note: If you try to back up a file
which is larger than the space you have allocated for your storage
area, Tivoli Storage Manager FastBack
for Workstations purges
all older versions of your files, and then fails to back up the file.
Make sure that the maximum space for your storage areas is greater
than the file size limit in the Advanced page
of the Tivoli Storage Manager FastBack
for Workstations.
Continuous protection level list
Tivoli Storage Manager FastBack
for Workstations offers
two levels of protection for your files: continuous protection and
scheduled protection.
Use this box to select which storage
areas to use for continuously protected files.
- None
- Files are not protected.
- Local storage only
- Tivoli Storage Manager FastBack
for Workstations creates
backup copies only on the local storage area.
- Remote storage only
- Tivoli Storage Manager FastBack
for Workstations creates
backup copies only on the remote storage area.
- Local and remote storage
- Tivoli Storage Manager FastBack
for Workstations creates
backup copies on both the local and remote storage areas. This choice
provides the most protection for your files, and is the default choice.
If your continuous protection level includes local
storage, Tivoli Storage Manager FastBack
for Workstations creates
backup copies in the \RealTimeBackup\ folder
on the nonremovable drive with the most free space.
Note: The
client can specify the drive for local storage, but the central administration console cannot.
The central administration console defines
a configuration that potentially applies to many clients, and it is
possible that not all the target computers have the same hardware
configuration. Hence, the central administration console configuration
specifies the default drive for local storage, which is the nonremovable
drive with the most free space.
