CrashPlan for Small Business Device Backup reference

Overview

The Backup tab under Settings > Device Backup allows you to control how and when backup operations take place, what files to include and exclude from backup, the frequency of backup, and how long versions should be retained. Advanced settings allow you to control backup processes like real-time file watching, data de-duplication, encryption, and compression.

General

Device Backup Settings, backup sets options

Item		Description
a	Backup Sets	Displays Backup Sets where you can create and configure backup sets.
b	Backup will run	Indicates whether backups are always running or running only at specific times.
		Always - Backup is always running.
		Between specified times - Backup will run only at specified times. When set to run between specified times, the Code42 app uses the time provided by the device's operating system.
c	Verify selection every	Scans system for file changes and deleted files within your backup selection at the interval and time of day you specify. If the computer is powered off or asleep at the scheduled scan time, the scan will wait until the next scheduled scan time to run.
d	Push	Applies these settings to existing devices in addition to new devices.

File selection

Device Backup File Selection

Item		Description
a	Included files	Adds pathnames of directories that should be included in backups of this device. Pathnames are case sensitive (see alert below).
b	+	Adds item to the Included filenames list.
c	Included filenames list	Displays pathnames of directories that are included in backups. A yellow folder icon indicates a folder. A purple document icon indicates a file. Click the X to remove an item from the list.
d	Excluded files	Adds pathnames of directories that should be excluded from backups of this device.
e	+	Adds item to the Excluded filenames list.
f	Excluded filenames list	Displays pathnames of directories that are excluded from backups. A yellow folder icon indicates a folder. A purple document icon indicates a file. Click the X to remove an item from the list.
g	Push	Applies these settings to existing devices in addition to new devices.

Consideration: Keep in mind that excluding previously selected files results in excluded files being deleted from the backup archive. The now-excluded files will not be available for restoring.

Included and excluded files
Inclusions are processed first, followed by exclusions. Files that are in both the inclusions and exclusions will be excluded, since the exclusion list is processed last.

Incorrect drive-letter capitalization may cause data loss
Drive letters are case sensitive. Adding a file path with incorrect capitalization of the drive letter removes all files from the backup file selection for devices with a different case drive letter. For example, adding a file path that starts with lowercase c (such as c:\Users) removes the backups of files whose actual path on disk starts with a capital C (such as C:\Users).

See also Real-time changes not detected due to case sensitivity for details about directory-name case sensitivity.

Do not use UNC file paths
Code42 does not support UNC file paths (for example, //SERVERNAME/shareddir/). The Code42 app appears to back up your files, but there is no way to restore them later because the file path is invalid, and thus the archive-maintenance process removes those files from the archive. This is a data-loss scenario.

File selections must use an absolute path (such as a C: drive) to ensure backup and restore ability.

Filename exclusions

Device Settings, Filename exclusions

Item		Description
a	Platforms	Displays excluded filename patterns per platform.
b		Enter filename pattern to exclude from backup.
c	Regular Expression	Enter text in the form of a Regular Expression (regex).
d	+	Adds text in text box to list of filename patterns to exclude.
e	Import	Displays window in which you can paste the contents of a text file with filename patterns / regex items you wish to exclude.
f	Export	Displays window in which you can copy the contents of the excluded files list, which you can in turn paste into your favorite text editor for editing.
g	Push	Applies these settings to existing devices in addition to new devices.

Frequency and versions

Frequency and Versions settings

Item		Description
a	Frequency - Back up new version	Indicates how often CrashPlan for Small Business (previously CrashPlan PRO) backs up and creates new versions of files in your archive.
b	Versions to retain from last week	Indicates which versions to keep from last week (not including today).
c	Versions to retain from last 90 days	Indicates which versions to keep from last 90 days (not including last week).
d	Versions to retain from last year	Indicates which versions to keep from last year (not including the last 90 days).
e	Versions to retain from previous years	Indicates which versions to keep from previous years (not including last year).
f	Remove deleted files after	Period after which deleted files are removed from the archive.
g	Push	Applies these settings to existing devices in addition to new devices.

Advanced settings

Advanced Settings

Item		Description
a	Data de-duplication	Controls data de-duplication rate.
		Automatic - Full de-duplication is used when going over an Internet connection. Minimal is used when going direct to disk or over LAN.
		Full - Every effort is made to identify duplicate data. While being 100% effective, it requires a great deal of CPU power. You're sacrificing CPU and speed to save bandwidth and disk at destination.
		Minimal - Several methods are used to identify duplicate data. While about 90% effective, it requires far less CPU power and will speed up initial backup speed significantly, typically 400% on a single processor system.
b	Compression	Controls how Code42 service compresses your backup. Compressed backups use less bandwidth and less disk space. Compression does consume some CPU, but not enough to offset overhead due to maxing out your bandwidth or I / O. Because you generally have more CPU available than bandwidth or disk I / O, we do not recommend turning off compression.
		Automatic - Files that do not compress well or are already compressed are not compressed by Code42 service.
		On - All files are compressed.
		Off - No files are compressed.
c	Encryption enabled	Indicates whether encryption is turned on.
d	Watch file system in real-time	Indicates whether Code42 service is constantly monitoring for file changes. See How Backup Works for more information.
e	Back up open files	Indicates whether files that are open (in use) at the time of back up will be backed up. See Backing Up Open Files And Databases for more information.
f	Push	Applies these settings to existing devices in addition to new devices.
