Creating Container Backup

On the New Backup screen you are supposed to define all the parameters of the backup operation.

In the Backup Description section, enter any commentary you think can be practical for further backup operations.

In the Backup Options section, define the level of compression and the type of the backup:

• On the Backup Type drop-down menu, select one of the following types of backup:
  • Full backup. This type is recommended when doing a backup job for the first time and contains all the data selected for the backup. A full backup storage space and completion time requirements are the highest.
  • Incremental backup affects only those files and data which have changed since the last backup and takes less storage space and creation time.
  • Differential backup includes only the data modified since the last full backup. (Whereas a differential backup will save the data changed after any last backup, be it a full, incremental, or differential, this is only a full backup a differential backup considers to be the last one.)

  You can also leave here the default Use Hardware Node Settings value. In this case, every Container will be backed up with the default backup parameters of its Hardware Node. To view or set the Hardware Node default backup parameters, select a Hardware Node and click Configure -> Container Backup Settings on the top toolbar.

• On the Compression Level drop-down menu, choose one of the possible levels:
  • None. This level suggests no compression at all and is recommended if you need to perform a fast backup but do not need to save disk space necessary for backups storage;
  • The normal level of compression takes a little more time and allows for some disk space saving;
  • While extending the backup creation time, the high level of compression saves you even more disk space;
  • The maximum compression level means the longest backup creation time and the best backup compression.

    Note: It is recommended to choose the backup compression level according to the type of the data the Container stores. The Virtuozzo Containers software will try to compress the backup regardless of the data type, but some data are worth spending time for compression (such as text files and data bases) and some, such as already compressed archives are not. Therefore, select the None checkbox when the Container you are backing up stores no data that suggest or need compressing.

  You can also leave here the default Use Hardware Node Settings value. In this case, every Container will be backed up with the default backup parameters of its Hardware Node. To view or set the Hardware Node default backup parameters, select a Hardware Node and click Configure -> Container Backup Settings on the top toolbar.

• On the Backup Node drop-down menu, select the Hardware Node that will be used for storing the created backups.

  You can also leave here the default Use Hardware Node Settings value. In this case, every Container will be backed up with the default backup parameters of its Hardware Node. To view or set the Hardware Node default backup parameters, select a Hardware Node and click Configure -> Container Backup Settings on the top toolbar.

The Exclude section allows you to keep certain files and directories from backing up:

• Hidden files;
• System files;
• Single files or directories. If you do not want to back up a whole directory, type it into the corresponding field; to add more directories to be excluded from the backup, click the plus sign.

  Warning! If you exclude one or more system or hidden files/folders from the Container backup (e.g. either the Hidden files or System files checkbox is selected), you'll be able to restore only separate files from this backup, but not the Container as a whole.

The Include section allows you to limit the backup process with a number of selected files or directories inside the Container. In the field provided, type the absolute path to the file or directory you wish to back up. To include additional files or directories, click the plus icon to the right of an existing path and enter a new path.

The backup will contain only those files and directories that you have indicated in the Include section. To back up the whole Container, leave the Include section empty.

You can also delay the backup operation till the time specified in the Backup Start group of options.

To start performing the backup, click Backup, otherwise, click Cancel.
