Backup method
|
The following options are available:
-
Full - Back up entire database or filegroup. Select this option
to back up the entire database or filegroup. This option is
selected by default.
See Backing up SQL databases.
-
Log - Back up transaction log. Select this option to back up
only the data contained in the transaction log; it does not back up
database data. After the transaction log is backed up, committed
transactions are removed (truncated).
Select this option to be able to select No recover - Place
database in loading state or Standby - Place database in standby
state under Enable advanced log backup options.
See Backing up SQL transaction
logs.
-
Log No Truncate - Back up transaction log - no truncate. Select
this method only when the database is corrupted or database files
are missing. Since the Log No Truncate method does not access the
database, you can still back up transactions that you may not be
able to access otherwise when the database is in this state. You
can then use this transaction log backup along with the database
backup and any previous transaction log backups to restore the
database to the point at which it failed; however, any uncommitted
transactions are rolled back. The Log No Truncate method does not
remove committed transactions after the log is backed up.
See Backing up SQL transaction
logs.
-
Differential - Back up database or filegroup changes only.
Select this option to back up only the changes made to the database
or filegroup since the last full backup. Because differential
backups allow the restore of a system only to the point in time
that the differential backup was created, you should also create
multiple log backups between the differential backups.
-
Database Snapshot (SQL 2005 or later) - Read-only, point-in-time
copy of another database - Select this option to create a read
only, point-in-time copy of another database.
See About SQL 2005/SQL
2008 database snapshots.
-
Full Copy-only (SQL 2005 or later) - Back up entire database or
filegroup without affecting future differential or log backups -
Select this option to back up the entire database or filegroup
without affecting future differential or log backups.
Unlike the Full backup method, the Full Copy-only backup method
does not reset the SQL 2005 differential baseline that is used to
indicate the database blocks that have changed since the last full
backup.
After making a full backup, you can use the Full Copy-only
backup method to make a copy of a SQL 2005 database without
affecting the baseline backup set required to run future
differential backups.
|
Database snapshots to keep
|
(SQL 2005 only) Use this option to select the number of database
snapshots to keep on disk. As the threshold is met, older database
snapshots are deleted, which are then replaced with new snapshots.
Because database snapshots continue to grow as the SQL 2005
database is updated, limiting the number of snapshots enables you
to minimize both the disk space and SQL Server processing time that
is required when the snapshots are updated.
See About SQL 2005/SQL
2008 database snapshots.

Consistency check before backup
|
Select one of the following consistency checks to
run before a backup:
-
None. Select this option if you do not want a consistency check
to run before a backup. Symantec strongly recommends that you
always run a consistency check either before or after the backup.
This option is selected by default.
-
Full check, excluding indexes. Select this option to exclude
indexes from the consistency check. If indexes are not checked, the
consistency check runs significantly faster but is not as thorough.
Only the data pages and clustered index pages for each user table
are included in the consistency check. The consistency of the
nonclustered index pages is not checked.
-
Full check, including indexes. Select this option to include
indexes in the consistency check. Any errors are logged.
-
Physical check only. Select this option to perform a low
overhead check of the physical consistency of the database. This
option only checks the integrity of the physical structure of the
page and record headers, and the consistency between the pages'
object ID and index ID and the allocation structures.
The Physical check only option is not supported under SQL
7.0.
|
Continue with backup if consistency check fails
|
Select this option to continue with the backup operation even if
the consistency check fails. You may want to continue with the
backup when the consistency check fails if you think that a backup
of the database in its current state is better than no backup at
all, or if you are backing up a very large database with only a
small problem in a table.
|
Consistency check after backup
|
Select a consistency check to run after a backup. Because
database transactions can occur during or after the consistency
check, but before the backup runs, consider running a consistency
check after the backup to ensure the data was consistent at the
time of the backup.
The following options are available:
-
None. Select this option if you do not want a consistency check
to run after a backup. Symantec strongly recommends that you always
run a consistency check either before or after the backup. This
option is selected by default.
-
Full check, excluding indexes. Select this option to exclude
indexes from the consistency check. If indexes are not checked, the
consistency check runs significantly faster but is not as thorough.
Only the data pages and clustered index pages for each user table
are included in the consistency check. The consistency of the
nonclustered index pages is not checked.
-
Full check, including indexes. Select this option to include
indexes in the consistency check. Any errors are logged.
-
Physical check only. Select this option to perform a low
overhead check of the physical consistency of the database. This
option only checks the integrity of the physical structure of the
page and record headers, and the consistency between the pages'
object ID and index ID and the allocation structures.
The option Physical check only is not supported under SQL
7.0.

Enable advanced log backup options
|
Select this option to choose either the No Recover - Place
database in loading state option or the Standby - place database in
standby state option to apply to the backup.
This option is only available after you select the backup method
Log - Back up transaction log.
|
No recover - Place database in loading state
|
Select this option to put the database in a loading state when
the log file backup completes. Users cannot connect to or query the
database while it is in a loading state.
This option is only available after you select Enable advanced
log backup options.
|
Standby - Place database in standby state
|
Select this option to put the database in standby mode when the
log file backup completes. Users can connect to and query the
database when it is in standby mode, but cannot update it.
You can convert a standby database to a live database by
restoring the latest transaction log. Ensure that you select the
following recovery completion state Leave the database ready to
use; additional transaction logs or differential backup cannot be
restored.
This option is only available if Enable advanced log backup
options has been selected.
This option is not supported for SQL 7.0.
|
Use checksums on backup (SQL 2005 only)
|
Select this option to have SQL 2005 add checksums to the SQL
2005 database data being backed up by Backup Exec. Adding checksums
to the data being backed up is required if you want to use the
option Run verify only; do not restore data. Using this option,
along with Run verify only; do not restore data, ensures that
during a restore of the SQL database, you are restoring from a
verified SQL 2005 backup.
|
Create on-disk copies of SQL backups to be placed on the SQL
server where the database is located
|
Select this option to create an on-disk copy of the SQL database
being backed up. This option lets you simultaneously back up a SQL
database to storage media while also writing a copy of the database
to a disk path you specify in the Save to path box.
This option gives IT administrators the ability to back up SQL
databases while also providing database administrators with copies
of the database on disk, which can be used for such things as tests
and restores.
|
Save to path
|
Enter a path in which to save on-disk copies of SQL backups.
|
SQL Server 2008 Enterprise Edition software compression (SQL
Server 2008 Enterprise Edition only )
|
Select the compression setting you want to use for this backup
job. Select None if you do not want to use compression. Select
Compress if you want to use SQL Server 2008 compression.
SQL compresses the data on the computer on which SQL Server 2008
Enterprise Edition is installed. Therefore, faster SQL 2008 backups
should occur if you use SQL compression.
If you back up remote SQL 2008 computers and you use SQL 2008
software compression, you must use the latest version of the Remote
Agent.
You can find a list of compatible operating systems, platforms,
and applications at the following URL:
http://entsupport.symantec.com/umi/V-269-1
Symantec recommends that you do not use SQL 2008 software
compression in a backup job that uses Backup Exec-initiated
software compression. Minimal additional SQL 2008 compression
benefits are gained when you enable Backup Exec compression. In
fact, in jobs where both compression schemes are used, backup times
may increase.
SQL 2008 software compression is not used if a backup job that
includes SQL 2008 data uses the Advanced Open File Option.
