File Backup and Recovery

Backups – 4 types to Maintain SystemBootable Clone TapeDaily BackupWeekly BackupMonthend Backup

Backup - Bootable Clone Tape

Creating a mksysb tape*:1. Signon as root2. Type in df >/tmp/df.log4. Type smit mksysb

*Should be run once per month

Bootable Clone Tape (maksysb)

(press F4 List for options)

Daily Backup

The nightly backup command looks like:

cd /

find data13 olog prt tss home var/spool/mail/*cqcs -print | cpio -ovcC32 > /dev/rmt0

bkuptss.sh

(You must be in the root directory!)

Weekly Backup

The weekly backup command looks like:

cd /find . -print | cpio -ovcC32 > /dev/rmt0

bkupall.sh

(You must also be in the root directory!)

Month end Backup

Run during the month end process.Additional scripts used for backup:

ARMOV - run before MBS080 (AR Month Start)

APMOV - run before MAP027 (AP Month Start)

GLMOV - before MGL013 (GL Monthly Update)

Restore

Using the CPIO command to restore

An example of a restore command:cpio –ivcC32umdl < /dev/rmt0 "data13/live/WOBR*"

This command will restore the WOBR* to the disk

Compared to the full backup command:find . -print | cpio -ovcC32 > /dev/rmt0

Recovery

Why Recover?What you need: Clone Tape (mksysb tape)
