SAVSYS is a backup of operating system -related objects.  It is one portion of a complete backup, but it is not a full backup of the system.

Sometimes people ask this question thinking they are asking how to do a complete backup of the system.

To do a complete backup of the system, do and "option 21" backup from the Save menu (GO SAVE).

If you are on V5R4 or later, you can save to "virtual tape", a disk-based object  that emulates tape.  This object can then be moved using FTP.

Complete backup and recovery documentation is available int he IBM Information Center for your OS Release in the System Management section, under Backup and Recovery.  Here's the System's Management link for V6R1, for example:

Hi,

My system is a 515 upgraded with more hd and ram running v5r4.

A full backup needed.

Here's what you need to do.  Read this:

http://publib.boulder.ibm.com/infocenter/iseries/v5r4/index.jsp?topic=/rzaiu/rzaiurzaiu267.htm

Then follow the checklist here:

http://publib.boulder.ibm.com/infocenter/iseries/v5r4/index.jsp?topic=/rzaiu/rzaiurzaiu2tv.htm

Remember that you can't restore the operating system from virtual tape, so for full-system recovery, you need to back up to tape or an optical device that can be used as an IPL source.

Hi,


Thanks a lot for this info.

Also, I readed some topic about people who could not start server after this command and something like this.


Any advise?
Gary PattersonVP Technology / Senior Consultant

Commented:
Maybe they just didn't know how to restart their system?  After an option 21 backup completes is a good time to IPL the system:

GO POWER, option 4.

The system will power down normally, power back up automatically, and start running the system startup program, which should restore the system to normal functioning condition.

If you are running a system with multiple logical partitions, you need to take care to shut down the secondary partitions before powering down the main partition.

Here's information on starting and stopping the system:

how to know the total amount  to be backuped? in order to select the correct slr device slr60 slr140....
Gary PattersonVP Technology / Senior Consultant

Commented:
If you just have one ASP (Auxiliary Storage Pool - means "Disk pool") configured, you can just use the DSPDSKSTS command.

It will show you the size of the System ASP, and what percentage of that disk pool is used:

System ASP:   350.9G
%System ASP used:  39.12%

350.9 x 39.12% = 137.27G used

Plan for 10% more than this when backing up, but be aware that data compression will probably produce significant savings.  How much depends entirely on the characteristics of data stored on your system, but it isn't unusual to see 2:1 compression, or better.

If you have multiple ASPs (or don't know), then use iSeries Navigator (a Windows program that is part of iSeries Access for Windows) and navigate as follows:

Configuration and Service - Hardware - Disk Units - Disk Pools.
This will show you a list of all configured disk pools, total storage in each pool, and % full for each pool.
