    Overview

    The Settings > Backup page contains settings that determine when CrashPlan runs, the number of versions of files to keep, and when to remove deleted files. Settings > Backup also provides access to advanced performance settings and backup set configuration options.

    Backup Settings

    Backup Settings

    Item Description
    a Backup will run Always - CrashPlan is always running (recommended setting).
      Between specified times - CrashPlan runs only during the time range you specify. For example, you may want to run only between 6 a.m. and 9 a.m. You can also choose the days of the week you want backups to run. Backup is only allowed to run during this timeframe.

    d

    Verify backup file selection every Scan 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.
    e Now Force the file selection verification scan to begin immediately.
    f Frequency and versions: Configure… Display window in which you can specify how often CrashPlan backs up and which versions to retain.
    g Filename exclusions: Configure… Display window in which you can enter file extensions to be excluded from your backup.
    h Advanced settings: Configure… Settings for disabling/enabling data de-duplication, compression, encryption, real-time file watching, and backing up open files.
    i Backup sets… Enable Create backup sets; view and edit backup set options. Once backup sets are enabled, the Backup tab displays additional options. View screen with backup sets enabled.
    j Undo Changes Reset to previous settings (same effect as cancel).
    k Save Apply changes.

    Frequency And Versions Settings

    Backup Frequency and Version Settings

    Item Description
    a Backup frequency Indicates how often CrashPlan backs up a file.
    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 Defaults Return settings to original default.
    h Cancel Ignore changes.
    i OK Apply changes.

    Consideration

    The frequency range depends on the setting for the previous interval. For example, the setting for “Last year” cannot be greater than the setting for the last 90 days.

    Filename Patterns To Exclude Settings

    Filename Patterns to Exclude Settings

    Item Description
    a Extension File extension to exclude.
    b Add Click to add another file extension to exclude. After you click, the extension appears in the window (d).
    c Regular Expression Click to enter regular expressions using Java regex syntax.
    d Exclusions List of exclusions that have been added.
    e Cancel Ignore changes.
    f Ok Apply changes.

    Consideration

    Excluding files previously selected for backup marks the excluded files for deletion from the backup archive. Newly excluded files are purged from the backup archive during the next scheduled Archive Maintenance. Once excluded files are purged, they are gone forever and cannot be restored.

    Advanced Settings

    Settings for disabling/enabling data de-duplication, compression, encryption, real-time file watching, and backing up open files.

    Advanced Settings

    Item Description
    a Data de-duplication Controls data de-duplication rate.
      Automatic - Full compression is used when going over a slow 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. With this setting 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, this setting requires far less CPU power and will speed up initial backup significantly, typically 400% on a single processor system.
    b Compression Controls how CrashPlan 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.
      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 is constantly monitoring for file changes. When enabled, this setting allows CrashPlan to avoid scanning your system for changes. Turning off this setting means that changes will be detected only during a nightly scan or when users press Scan.
    e Back up open files     Indicates whether files that are open (in use) at the time of back up will be backed up.
    f Cancel Ignore changes.
    g Ok Apply changes.

    With Backup Sets Enabled

    When you enable Backup Sets, the Settings > Backup screen displays the below options.

    Multiple Backup Sets Backing Up To A Single Destination
    Backup sets can back up to separate destinations or share a destination. Before creating multiple backup sets that back up to a single destination, please read these important considerations.
    File exclusions
    File exclusions specified for any backup set impact all sets backing up to the same destination. For example, suppose Set A and Set B back up to an external hard drive destination. Set A has an exclusion indicating that files ending in .mp3 shouldn't back up. Even though you haven't specified this exclusion for Set B, MP3s from this set will not back up to the external hard drive. 
    Frequency and version settings
    Only one set of version and deleted file retention settings can be applied to backup sets backing up to a single destination:
    • When multiple backup sets back up to a single destination, the version and deleted file retention settings from the backup set with the highest priority are applied to all sets backing up to that destination.
    • If you would like different backup sets to have different version and deleted file retention settings, back up to multiple destinations.​

    Backup Settings With Backup Sets Enabled

    Item Description
    a Backup set list     List of existing backup sets.
    b Name Name for this backup set.
    c Priority Indicates the sequence in which the selected backup set will run.
    d Add Creates a new backup set. By default, new backup sets have no files selected or destinations specified.
    e Remove Deletes the selected backup set. Backed up files will be removed from their respective destinations in the backup set.
    f Duplicate Makes a copy of the selected backup set, including selected files, destinations and settings.
    g Files Specifies the file/folders to be included in your backup. You can select as many files or folders as you want.
    h Change... Display file tree where you can change (add or remove) files for backup.
    i Files / Backup Size Number of files you are backing up.
    j Destinations List of backup destinations for this backup set. 
    k Change... Displays Destinations window where you specify the destinations for the backup set.
    l –     Destination info includes type of destination, amount stored so far, time of last backup.
    m Backup will run Always - CrashPlan is always running.
      Between specified times - CrashPlan runs only during the time range you specify. For example, you may want to run between 6 a.m. and 9 a.m. You can also choose the days of the week you want backups to run. Backup is only allowed to run during this timeframe.
    n Verify backup file selection every    

    Scan 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.

    Note: CrashPlan alerts you if the time you set to run the verification scan is outside the timeframe you've allowed CrashPlan to run.

    o Now Force the file selection verification scan to begin immediately.
    p Frequency and versions - Configure… Display window in which you can specify how often CrashPlan backs up and which versions to retain.
    Note: When multiple backup sets back up to a single destination, the frequency and version settings from the backup set with the highest priority are applied to all sets backing up to that destination.
    q Filename exclusions - Configure… Display window in which you can enter file extensions to be excluded from backup.
    Note: When multiple backup sets back up to a single destination, exclusions applied to one set are applied to all sets that back up to the same destination.
    r Advanced settings - Configure… Settings for disabling/enabling data de-duplication, compression, encryption, real-time file watching, and backing up open files.
    s Undo Changes     Reset to previous settings (same effect as cancel).
    t Save Apply changes.
