Hello,
I want to make a hot backup of my informix data to post on the local networks of the company.
example, the IP address of my server is 192.168.2.10 and I want to make a hot backup to another server that each IP address 192.168.2.12

its possible? what I can do ? i want using the command ONBAR (can you give me the syntax and a small script that allows me to do this operation?)

thank you very much

Using the resources appropriately (samba or nfs) , yes , is possible...
scripts? well, onbar is a little annoying to configure... read the manual...sorry...

if you want to use the ontape, is more easily to say how to do.

ok! can you help me to do a backup with ontape command? the command syntax, with daily backup and weekly
thank you very much

What version of IDS and OS?

OS: RHEL : REDHAT ENTERPRISE LINUX Release 4
IDS: 10

Considering :
ServerA = Informix running
ServerB = Target to save backup

Basic steps.
1) Share the disk on ServerB (with samba or nfs)
2) Mount the ServerB directory on ServerA
Let's suppose you mount in the directory: /RemoteBackup
(all this is OS knowledge, if you don't know how to do, please , search on internet , isn't hard to do)

3)Configure your ONCONFIG , the parameters TAPEDEV and LTAPEDEV :
WARNING: this way you don't have backup of any logical log, if you want to backup the logical log , you have some options what I explain at the end of this post.

4) create the backup file with informix user and set the right permission :
5) Execute the backup
Where the "-L 0" means Level 0 (full backup), if you want a incremental backup, you still have 1 and 2 levels :
But , remember, if use increment backup, to restore the level 2 , you will need the level 1 and 0 previous backuped.

The ontape always ask if the tape are mounted. If you want to automatize this process in a shell script use:
So, to create a full or incremental backup, that is all...

To create the logical logs backup you can use 2 commands;
The "-c" means "continuous" backup , where the ontape command not stop running still the user/operator press CTRL+C or the space where the backup are written become full..
The "-a" means "automatic" backup, where the ontape command backup only the not-backuped logical logs (you can check this with "onstat -l" ).

So, remember , the parameter on the ONCONFIG aren't dynamic , so every time you execute the ontape, the old file will be overwritten . This way , is high recommend you rename the fille after execute the ontape.


I don't detail to much, because this is the basic guideline and depend how your enviroment are configured and how you want your backup work...
