The Advanced options affect the overall operation of the software.
Backup options that normally do not need to be changed are also located on this tab.
· Software Updates:
· Check for New Versions:
How frequently the software should check for newer software versions.
How frequently the software should check for newer software versions.
· Automatically Install Updates:
If this is checked, then after each backup (or when the backup manager is running) it will automatically download and install software updates. If this is unchecked, updates will automatically be downloaded, but you will be asked if you want to install the update before it proceeds.
You probably do not want to turn this option on if you are using a software firewall or Internet security product that restricts outbound Internet access only to approved applications. This is because if the software is continually changing, your security software will treat the backup program as a new program and will block its Internet access until you manually tell your firewall to approve access. If you always allow outbound traffic on port 443 (or port 5470 if you are configured to use that port instead), then it is safe to turn on this option.

· Treat Minor Versions as Major Versions:
Software updates are classified by our development team as either minor or major. Minor updates are more frequent and contain minor feature updates or specific bugfixes. If this is set to No then it will only automatically install major versions (if you have automatic installs of updates enabled). You may always use the software updates tab on the system status page to check for a new version (minor or major) at any time.

· Software Security:
· Access Control Level:
You can prevent users who do not know your account password from changing your backup settings (even if they are an administrator on this machine). If you change this option to Require Account Password then your settings will be locked and cannot be changed until they are unlocked.
There is a button in the lower-left hand corner of the window that can be used to unlock the settings. Settings will remain unlocked for 30 minutes, or until you re-lock the settings using the button, or until the program exits (whichever comes first).

· Access Control User List:
If the Access Control Level is set to Require Account Password then normally it will ask for the password of the account currently configured on the My Account page in the software before allowing settings to be changed. This setting forces the software to only allow changes if the correct password is typed for one of the accounts listed in this setting.
This setting can be used to lock down the software so that the settings can only be changed by someone who knows the password for a specific account. This setting should contain the list of usernames of the users authorized to change the backup settings. Multiple users can be specified by separating usernames with commas.

· Start Backup Manager at Logon:
If enabled, the backup manager will automatically start when the current Windows user logs in to Windows.

· Windows Registry:
· Registry Storage Location:
The software can either store its settings in either a machine-specific location (HKEY_LOCAL_MACHINE) or a user-specific location (HKEY_CURRENT_USER). This is an advanced setting. Normally you should always store the settings in a machine-specific location.

· Use Secure ACLs:
If this option is enabled it uses Windows security features to restrict non-administrators from reading or modifying the configuration of the software in the Windows registry. It should always be left on in almost all circumstances.

· Backup Engine:
· Number of Concurrent Connections:
Large data sets may backup faster if more than one file is backed up at the same time. This setting determines how many files can be backed up concurrently.
Large data sets may backup faster if more than one file is backed up at the same time. This setting determines how many files can be backed up concurrently.
· Maintenance Mode:
Every 7 to 14 days, extra work is performed on the account, such as checking for old deleted files to purge and to verify all data that should be stored in the backup is actually stored in the backup. This process can take quite a while if there are hundreds of thousands of directories. Set the maintenance mode to Background to have this work be performed in the background and not during the main backup job. This ensures that backup jobs do not take longer than normal. The maintenance running in the background will not interfere with backup jobs running at the same time.

· Extra Days Between Maintenance:
Accounts with millions of directories in the backup set may want to run account maintenance work once a month instead of once every 7 to 14 days. Change this setting to 24 to enable such a strategy. We also recommend setting the Maintenance Mode to Background for accounts this large.

· Directory Cache Size:
For performance, during backups while changed files are being uploaded in the foreground, a background process is scanning the directories in the backup set to determine which files have changed. This determines how "far ahead" this background process can get. Increasing this value has the potential to increase performance for accounts with millions of directories, but does require more memory. Typically the default setting of 10,000 is a good balance.

· Always Check Block Fingerprints:
Data Protection uses the modification date and time and size of a file in order to quickly determine if the file has changed since the last time it was backed up. For certain types of files, this technique is not sufficient to detect all changes.
For example, Microsoft Exchange and SQL server can write data to a file for several days or even weeks without causing the modification date on the file to change. In general, any application that will keep a file open for days, weeks, or even months without re-opening the file will need to have the file contents scanned in order to detect changes.
Turning this option on tells the backup engine that it must scan the contents of files in order to determine whether or not they have changed. Typically you do not turn this option on for all folders here, but rather you turn it on only for the specific top-level folders that contain the data that needs the more thorough change-detection technique (such as Exchange and SQL server data). Please see our knowledge base for more information.
Note that Data Protection will always scan the contents of the following file types to detect changes: .chk, .edb, .stm, .mdb, .ldb, .mdf, .ldf, .ndf, .db, .vhd, .vmdk, .vdi.
WARNING: Do not change this setting to Disabled without contacting technical support.

· Local Backup Engine:
· Synchronous File Updates:
Whether or not to force the flushing of the target medium's physical write buffers after backing up each file for local disk backups. (For remote backups this is always enabled.)

· Periodically Flush Buffered Writes:
Certain file systems or NAS devices may have trouble if the local disk backup is too fast and the target storage device has a very large write cache. Enabling this option will cause the write buffer to be flushed every 5 MB, and may help improve backup stability if the backup target medium is heavily loaded or stalls out periodically.
