Customer Story - TMHE
Hot Backup with CDP
TMHE (part of Toyota Industries Corp) provides a
complete range of Toyota counterbalanced forklift
trucks and BT warehouse equipment, supported by
services and added value solutions. TMHE employs
4,000 service technicians and is active in more than
30 countries across Europe.
iTERA AVAILABILITY is used to maintain remote
real-time HA/DR environments for the mission critical
Lawson M3 and Movex environments. 24X7
operation is maintained by eliminating down time
during tape backups and planned maintenance and
ensuring fast recovery with no data loss after any
unplanned outage. Industry leading autonomic
capabilities help ensure this is a low maintenance and
flexible solution.
MIMIX RECOVERNOW is used to provide an
additional level of protection for the mission critical
Lawson M3 environment. Data changes are
replicated from the M3 hot backup system to another
remote location where they are stored in a disk vault
for roll-forward recovery after a tape restore. This
allows recovery of objects and libraries to a specific
historical point in time and also provides DR for the
hot backup system during planned maintenance
operations.

MIMIX® RecoverNow 5.1
Recover More Data Than With Tape Alone*(1)
System i DR & CDP
*(1) Typical RPO with tape alone backups is 24 hours.
Typical RPO with RecoverNow is 15-30 minutes
Nightly backups to a local/remote disk*(2)
Users remain on-line during nightly backups
Data changes saved to disk between backups*(3)
Allows recovery potentially right up to point of failure
Or recover data to any historical point in time (CDP)
Uses any TCP/IP disk storage platform (e.g. Windows)
Data compressed on disk typically by 60%
Automates journaling for data capture
Easy to set up and manage
Easy to restore data to a new system/LPAR
Used also for data migration / test environments
Use stand alone or to add CDP to Vision HA
*(2) Optionally nightly backups can be to tape, compatible with BRMS
*(3) Typically every 15-30 mins. User configurabl interval
Recover Objects To Any Historical Point In Time

Standard Tape Backup
Typically Gives 24 Hour RPO
Backup to
Tape
There is typically a 24 hour interval between tape backups
This means there is typically a potential for 24 hours of data loss!
Lost data must be re-keyed after the tape backup is restored
24 hours of lost data can take days or sometimes weeks to re-key!
Nightly backups typically introduce down time
Tip: Recovery Point Objective (RPO) with tape is the
number of hours between tape backups

MIMIX® RecoverNow Backup
Typically Gives 15-30 Minute RPO
Backup to
Disk
Data changes are captured and
‘pushed-to-vault’ frequently
between backups
There is typically a 24 hour interval between disk*(1) backups
Data changes are captured and pushed-to-disk between backups*(2)
Users can remain on-line during the disk backups
Recovery possible potential right up to point of failure
Recovery also possible to any historical point in time (CDP) *(3)
Tip: Recovery Point Objective (RPO) with RecoverNow is
the number of minutes between ‘push-to-disk’
*(1) Backups can be to disk vault or optionally to tape, its compatible with BRMS *(2) Push-to-vault is always to vault at user configurable intervals
*(3) CDP is continuous data protection

MIMIX® RecoverNow Architecture
RecoverNow
Storage Platform / Vault
Tip: RecoverNow is compatible with BRMS
so nightly tape backups can still be done to
tape using BRMS commands… RecoverNow
adds ability to save changed data to disk vault
in between backups

RecoverNow adds:
Data recovery to historical

Option to do hot backups
from local production system
Any TCP/IP
Storage Platform
Tip: HA environments let you recover only to last transaction
Adding RecoverNow adds recovery to a historical point-in-time
Tip: HA environments allow hot backups only from the recovery system
Adding RecoverNow allows hot backups also from the production system

Main Menu & System Controls
All options accessible from a single
menu
Before starting RecoverNow define
connection details to your remote
storage platform (vault) and how
journal receivers will be managed

Active Monitoring
RecoverNow runs automatically so
typically no user actions are needed.
The monitor shows all activity in the
RecoverNow subsystem (saves and
journal receiver pushed to the vault).
The monitor also verifies that all
libraries and objects are being saved
correctly.
Tip: Some compliance regulations
require that backups are actively
checked (unlike tape). The
monitor helps address that
requirement because it’s
proactive.

Saving With MIMIX® RecoverNow
The standard IBM SAVLIB,
SAVOBJ, SAV, SAVSECDTA,
SAVDLO, SAVCHGOBJ or
SAVCFG are embedded as
parameters of RecoverNow IVSAV
command which pushes the save
to the vault and starts journaling (if
it has not yet been started)
Typically libraries and objects are
saved while active because the
journal ensures recovery to a
specific point in time..
Tip: Set this up on the IBM
job scheduler to perform
Daily saves. RecoverNow
allows saves to be rotated
and recycled depending on
the capacity of the vault.

Restoring Libraries & Objects With MIMIX® RecoverNow
From the Work with Save History
screen, select option 12=Work saved
libraries/objects to display all the
libraries of a save.
Select option 15=Restore to
perform the restore. If you select
option 15 on more than one
library, the saves will be
processed one after the other.
Tip: Similar process if you
wish to restore individual
objects

Applying Journal History With MIMIX® RecoverNow
Apply the associated journal
receivers. A message will display
indicating that the apply process has
been submitted.
You are informed when the journal apply
process is finished, transactions are
‘rolled forward’ as if users and jobs had
been updating the data.
Tip: If you want to restore to
a historical point in time,
select only the receivers that
were pushed to vault before
that point.

Data areas and data queues currently not journaled
SAVCHGOBJ *ALL *ALLUSR , SAVSYSINF, SAVOBJ & SAVCHGOBJ using
multiple libraries currently not supported
For remote vaults a T1 line supports approx 1Gb/hour transfer rate
Bandwidth calculator:

SAVSYS is performed outside of RecoverNow to tape as recommended by IBM
In the event of total system failure…do the following:
1. IBM repair or replace the production system
2. Restore SAVSYS from tape
3. Connect to vault manually with TCPIP
4. Restore RecoverNow from vault to new system
5. RecoverNow now guides you to retrieve the save history and guides you to
restore the application libraries to the most recent journal receiver pushed to vault
Tip: No license key required for the restore…but you will need one to start saving again
to a new system. Contact CustomerCare.
