Figure 20. - Work with Job – Create New Backup Job

Job Name – A new definition, unique on this Agent, of up to 30 characters. Note: You may use A to Z, and 0 to 9, but you must NOT start with a number. Special characters _ (underscore) and $ (dollar sign) are also allowed.

Vault Name – (1 to 15 characters) Enter one defined earlier in “Work with Vaults”. Note: F4 will display a list of all current Vaults.

Data Type – Select one of the types of data included in the Job configuration: *OBJ, *IFS, *SYS

OBJ – Libraries and objects in native system.

IFS – Folders and stream files in Integrated File System.

SYS – System state data that contains system security data (SAVSECDTA), configuration objects (by SAVCFG command) and system values.

Note: Other than *SYS (System State), regular system objects include *ALLUSR and *IBM. With *ALLUSR, all user libraries are saved. This includes some libraries that IBM has supplied, but they typically contain user data that changes frequently, so are considered “User Libraries” as well. *IBM saves all system (IBM) libraries, which are considered “System Libraries”.

In the following descriptions, these definitions apply:

• Recursive: Take all libraries and all their contents (objects).

• Save Savefile data: Take contents of Savefile, or just the header information. • Save Active: SYSDFN (System Define) - Save in the current state. If NO, specify a

wait time. Or specify a Trigger for database backups.

• Save Active/Backup wait time: How long to wait before SYSDFN is available to be backed up.

• Deferring: If the Backup Job does not complete in your specified length of time (15 to 2880 minutes), it will pause and continue at the next scheduled Backup time.

• Encryption: Secures your Backup data on the Vault, so that it cannot be read without decrypting. You choose your strength of encryption type (or none).

2.4.1.1 Object Backup

Include Objects – Object name: This list can be up to 128 items (use + for more values). You may choose a single name, or *ALL, *ALLUSR, *IBM or use a generic name.

*ALL - All the objects in the specified library are saved.

*ALLUSR - All objects in user libraries are saved. QSYS becomes the only legal library name. If *ALLUSR is included in more than one entry, all the other entries will be removed.

*IBM - Saves all objects in system (IBM) libraries. QSYS becomes the only legal library name. If *IBM is included in more than one entry, all the other entries will be removed.

generic* - Specify generic name of a group of objects in the specified library to be saved. A generic name is a character string that contains one or more valid characters followed by an asterisk (*).

Library: Either name the library, or use QSYS for all libraries.

Type: Choose a specific type from the list (with F4), or *ALL for all types.

Exclude Objects – Object name: This list can be up to 128 items (use + for more values). You may choose a single name, or *ALL, *ALLUSR, *IBM or use a generic name. Note that a generic (partial) name will start with one or more valid characters, followed by an * (the wildcard).

Library: Either name the library, or use QSYS for all libraries.

Type: Choose a specific type from the list (with F4), or *ALL for all types. (See section 2.2.4 for details on working with Wildcard Exclusions.)

Recursive – YES or NO. Take all libraries and all their contents (objects).

Small Object Size (KB) – Specifies the size limit for objects to be backed up via save files. Objects bigger than a user-defined value set value will be backed up with an IBM API. Backing up small objects via save files drastically improves Restore times.

Save Savefile data – YES or NO.

Save Active – NONE, SYSDFN, or TRIGGER

Save Active/Trigger Wait Time – up to 99999 seconds, or NOMAX (wait forever). Default is 120 seconds. This is the time that the trigger will wait for a quiet period of no database activity, before the Backup starts.

Trigger Retry Period – up to 99999 seconds, or NOMAX (wait forever). Default is 3600 seconds. The trigger will retry for the active/Backup wait time for this retry period. If it does not succeed, the Backup will not start, and an error message will be entered into the log file.

Threading Model – If the Agent is on a multi-cpu system, you can use multi-threading to improve Backup and Restore performance. Choose DEFAULT, SINGLE, COMBINED, BLOCK PROCESSOR, or MAXIMUM BLOCK PROCESSOR. (See section 2.2.5) If you select F10 you will get more options:

Encryption (Type and Password) – NONE, DES56, BLOWFISH56,

BLOWFISH128, TRIPLEDES112, AES128, AES256. (If you use encryption, you will be prompted for a password and to verify that password.)

NOTE: If you lose your Encryption Password, your data is NOT recoverable!

Compression – To reduce the data transmitted and the data size at the Vault you can choose a compression type. Choose NONE, DEFAULT, STANDARD, NORMAL, MINIMUM, BETTER, MAXIMUM or FASTERRST. (See section 2.2.7)

Deferring (Disable and Minutes) – NO or YES. If NO, enter a time of 15 to 2880 minutes, or NODEFER to keep the Backup going until finished.

Quick File Scanning – YES or NO. Do you want to Backup any objects that have not changed since the last Backup.

Update History – YES or NO. (Suppress Archive bit.) If YES, the time/date of the Backup data will be changed.

Log Detail – This option specifies the amount and type of Backup details to be included in the log files. Choose FILE, NONE, SUMMARY, or DIRECTORY.

Disable CRC – YES or NO. You can choose to disable CRC to improve the performance of backups and restores. (See section 2.2.6)

2.4.1.2 IFS Backup

Include IFS stream files - Specifies a list of up to 128 entries of IFS paths that you want to Backup.

Absolute path - specifies the absolute path name of the stream files. File - The files in the specified directory are being saved.

Recursive - Specifies whether sub-directories are included in the Backup.

Exclude IFS stream files - Specifies a list of up to 128 entries of IFS stream files that you don't want to Backup.
