Device Backup Reference

Applies to:
  • CrashPlan PRO
  • Code42 CrashPlan (previously CrashPlan PROe)

Overview

The Backup tab under Settings > Device Backup allows you to control how and when Code42 CrashPlan 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 sheet in which 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 CrashPlan 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 Lock Locks this setting to prevent users from changing it in their personal settings.
Available in Code42 CrashPlan (previously CrashPlan PROe) only.
e Push Applies these settings to existing users in addition to new users.

File selection

Device backup settings, file selection options, included and excluded files

Item Description
a Include 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 Files list.
c Included filenames list Displays pathnames of directories that are included in backups. If the File Selection settings are not locked, users are allowed to add to this list and to remove selections from this list. Click the X to remove an item from the list.
d File Exclusion Adds pathnames of directories that should be excluded from backups of this device.
e + Adds item to the Excluded Files list.
f Exclude filenames list Displays pathnames of directories that are excluded from backups. If the File Selection settings are not locked, users are allowed to add to this list, and to remove selections from this list. Click the X to remove an item from the list.
g Lock Locks this setting to prevent users from changing it in their personal settings.
Available in Code42 CrashPlan (previously CrashPlan PROe) only.
h Push Applies these settings to existing users in addition to new users.

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.

User profile backup

This section allows you to view or modify Windows user profile backup settings for all organizations in your Code42 environment.

Windows User Profile Backup

Item Description
a Enable User Profile Backup Enables Windows user profile backup.
b Backup Frequency Defines how often Windows user profile backup runs.
c User Specifies a custom MigUser.xml. When an .xml is selected, the filename is displayed.
d App Specifies a custom MigApp.xml. When an .xml is selected, the filename is displayed.
e

Docs

Specifies a custom MigDocs.xml. When an .xml is selected, the filename is displayed.
f Exclusion Specifies a custom Custom.xml. When an .xml is selected, the filename is displayed.
g Custom Specifies a custom .xml. When an .xml is selected, the filename is displayed.
h ScanState Options Specifies command line options for the USMT ScanState.
i LoadState Options Deprecated - no effect.
j Push Applies these settings to existing users in addition to new users.

Destinations

This section allows you to choose which destinations are used by newly added devices immediately upon first signing in. Available in Code42 CrashPlan (previously CrashPlan PROe) only.

Destinations - no destination selected

Selecting a destination will cause new devices to automatically start backing up to it. Deselecting a destination will allow users to back up to the destination by clicking Start Backup in the CrashPlan app.

When you select at least one destination, the label changes from Auto-start to Use:
Destinations - one or more destinations selected

Filename exclusions

Device Settings, Filename exclusions

Item Description
a Platforms Tabs display filename patterns to hide.
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 Lock Locks this setting to prevent users from changing it in their personal settings.
Available in Code42 CrashPlan (previously CrashPlan PROe) only.
h Push Applies these settings to existing users in addition to new users.

Frequency and versions

Frequence and Versions settings

Item Description
a Frequency - Back up new version Indicates how often Code42 CrashPlan backs up and creates new versions of files in your archive.
b Versions to keep from last week Indicates which versions to keep from last week (not including today).
c Versions to keep from last 90 days Indicates which versions to keep from last 90 days (not including last week).
d Versions to keep from last year Indicates which versions to keep from last year (not including the last 90 days).
e Versions to keep 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 Lock1 Locks this setting to prevent users from changing it in their personal settings.
Available in Code42 CrashPlan (previously CrashPlan PROe) only.
h Push1 Applies these settings to existing users in addition to new users.

1 Code42 server version 5.4 and later provides one set of lock and push buttons that applies to both Frequency and Version retention settings. Code42 server versions prior to 5.4 had two pairs, one for frequency, one for retention. If either Frequency or Version retention is locked when a Code42 server upgrades to 5.4, then both will be locked when the upgrade completes.

Changes to frequency and version settings
Changes to frequency and version settings are applied to each backup archive after the user's device connects to the Code42 server.

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 CrashPlan 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 CrashPlan 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 CrashPlan service is constantly monitoring for file changes.
e Back up open files Indicates whether files that are open (in use) at the time of back up will be backed up.
f Lock Locks this setting to prevent users from changing it in their personal settings.
Available in Code42 CrashPlan (previously CrashPlan PROe) only.
g Push Applies these settings to existing users in addition to new users.
