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.
|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.|
|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).|
|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.|
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.
|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.|
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.
Settings for disabling/enabling data de-duplication, compression, encryption, real-time file watching, and backing up open files.
|a||Data de-duplication||Controls data de-duplication rate.|
|Automatic - Full de-duplication 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.|
When you enable Backup Sets, the Settings > Backup screen displays the below options.
|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).|
