Operating Systems AIX Help in understanding how backup and restore works in any organization? Post 302932608 by techy1 on Thursday 22nd of January 2015 06:25:41 PM

it maybe a lot of work without any tools but for this question:

How can we backup user data (not OS) on regular basis using OS commands ? incremental or full backups ?


Since you are taking a mksysb and hopefully on a remote server, depending on what the situations are like, allocate a new LUN make this a backup drive, use something like rsync to make the backups for you. I'm not really sure this will do incremental backups though.

Here is some info from rsync:
Code:
     Rsync copies files either to  or  from  a  remote  host,  or
     locally  on  the  current  host (it does not support copying
     files between two remote hosts).

ginstall - copy files and set attributes SYNOPSIS
install [OPTION]... SOURCE DEST (1st format) install [OPTION]... SOURCE... DIRECTORY (2nd format) install -d [OPTION]... DIRECTORY... (3rd format) DESCRIPTION
In the first two formats, copy SOURCE to DEST or multiple SOURCE(s) to the existing DIRECTORY, while setting permission modes and owner/group. In the third format, create all components of the given DIRECTORY(ies). Mandatory arguments to long options are mandatory for short options too. --backup[=CONTROL] make a backup of each existing destination file -b like --backup but does not accept an argument -c (ignored) -C Install file, unless target already exists and is the same as the new file, in which case the modification time won't be changed. -d, --directory treat all arguments as directory names; create all components of the specified directories -D create all leading components of DEST except the last, then copy SOURCE to DEST; useful in the 1st format -g, --group=GROUP set group ownership, instead of process' current group -m, --mode=MODE set permission mode (as in chmod), instead of rwxr-xr-x -o, --owner=OWNER set ownership (super-user only) -p, --preserve-timestamps apply access/modification times of SOURCE files to corresponding destination files -s, --strip strip symbol tables, only for 1st and 2nd formats -S, --suffix=SUFFIX override the usual backup suffix -v, --verbose print the name of each directory as it is created --help display this help and exit --version output version information and exit The backup suffix is `~', unless set with --suffix or SIMPLE_BACKUP_SUFFIX. The version control method may be selected via the --backup option or through the VERSION_CONTROL environment variable. Here are the values: none, off never make backups (even if --backup is given) numbered, t make numbered backups existing, nil numbered if numbered backups exist, simple otherwise simple, never always make simple backups AUTHOR
