Savepack

This screen displays details of the selected Savepack. To create a Savepack, click on Add a new savepack.

Name
Enter a name for the Savepack.
Compression type allowed
Click on this drop-down list to select the type of compression that will be applied to the files and directories included in the Savepack. Arkeia includes the Lempel Ziv compression scheme to obtain better performance on large files. The types of compression are:
Encryption type allowed
Click on this drop-down list to select the type of encryption that will be applied to the files and directories included in the Savepack. The encryption schemes that are available are:
Command before Savepack
It is possible to enter a command in this field that must be executed on the client before the backup of the Savepack.

Caution - Command before

Arkeia will not perform the backup if the command entered in the Command before Savepack field fails and returns a standard error code. For instance, if a tar command should be performed on some files before the backup, and tar returns a standard error code (an error code larger than 0 -- Success, then Arkeia will not perform the backup.

If the command did not perform as expected and returned an error code, but the backup should be performed nonetheless, click on the check box Backup Savepack if command fails below the entry field.

A command can be any standard UNIX command, a shell program, a batch file (on Microsoft® Windows® computers) or any other program that can be launched from a command line. The following commands are valid entries for a Command before Savepack:
machine_fqdn!file:/home/john/scripts/dump.pl (Perl script on a Linux machine)
windows_fqdn!file:c:/Program Files/Arkeia/Arkeia/myscript.bat (batch script on a Windows machine)


Command after Savepack
In the same way that a command can be entered to be executed before the backup of the Savepack, another command can be entered to be executed after the backup itself (see above for more details). To allow the execution of this command even if the backup itself has failed, click on the Execute if Savepack backup fails check box below the entry field.
Media server
When a backup job using this Savepack is run, the resulting backup data set will be sent to this media server for storage. The default is:
Click the button to see a drop list of available media servers, and choose another media server if you do not want to use the default.
Comment
Enter an optional comment about this Savepack.
Number of retries
Choose the number of times Arkeia will unsuccessfully attempt to access this Savepack before aborting.
Follow symbolic links
Choose whether Arkeia backs up the files to which symlinks in this Savepack refer.
Follow file systems
Choose whether Arkeia should backup different file systems in this Savepack.
File systems allowed
Choose which file systems will be backed up, and which will not be backed up.
Reset access times
Choose whether the access time for files in this Savepack is changed as a result of backup or restore operations.
Backup POSIX ACLs
Choose Yes if you want the file ACLs (Access Control Lists) in this tree to be saved on backup. The value No means that Arkeia will ignore any ACLs when backing up this Savepack. Note that the setting of Backup POSIX ACLs in Tree advanced options can override the setting you enter here. Setting POSIX ACL backup to Yes increases the processing overhead for every file, whether or not the file uses ACLs. For this reason, the default is No for ACL backup.
Backup Linux extended attributes
Choose Yes if you want the Linux extended attributes in this tree to be saved on backup. The value No means that Arkeia will ignore any Linux extended attributes when backing up this Savepack. Note that the setting of Linux extended attributes in Tree advanced options can override the setting you enter here.
Linux extended file attributes is a file system feature that enables users to associate computer files with metadata not interpreted by the filesystem, whereas regular attributes have a purpose strictly defined by the filesystem (such as permissions or records of creation and modification times). In Linux, the ext2, ext3, ext4, JFS, ReiserFS and XFS filesystems support extended attributes (abbreviated xattr) if the libattr feature is enabled in the kernel configuration.
For OES 2 users, this is possible to backup NSS information (Metadata and trustees) with this feature. Novell has implemented a way to push the extended attributes into the standard Linux xattr framework so that all of this specialized metadata can be preserved by standard Linux xattr APIs. The following lines must be added to the nssstart.cfg file:
/ListXattrNWMetadata /CtimeIsMetadataModTime
The nssstart.cfg file is found at:
/etc/opt/novell/nss/nssstart.cfg on OES 2 servers.
Find filter
Enter the name of a file containing a filter expression you wish to use.
Inclusion filter
Enter regular expression for the filename criteria you wish to include in this Savepack.
Exclusion filter
Enter regular expression for the filename criteria you wish to exclude from this Savepack.

Click on Create to save this Savepack. The Savepack is empty at first. To add the filenames to be backed up, click on the Savepack name in the Select a Savepack list, then Manage trees for... in the actions menu.
