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)
Full (weekly) system backup Daily BackupA copy of the df command
Two Step Process:Restore using one or more backup from aboveApply the TRANSACTION LOGGER.
Transaction Logger – Error Writing Recovery
1. Error writing recovery message in the morning:FIX: logon as root
chown prog:users /olog/RCLOGchmod 777 /olog/RCLOG
The users MUST log off and back on to clear the error.2. Error writing recovery message later in the day:
FIX: Moving existing RCLOG file to /data13logon as rootdf –k /olog (check here to see if 100%)mv RCLOG.Z /data13mv RCLOG /data13cp /tss/macros/RCLOG /olog/RCLOG
The users MUST log off and back on to clear the error.
