Re: zLinux backup solutions

2016-11-14 Thread Ponte, Douglas C. (JMD) 
Right, I should have specifically mentioned the use of FLASHCOPY/snap as the 
much preferred method to copying LIVE fullpack volumes with z/OS. 
As well as the need to determine compatibility, with respect to any COTS/vendor 
products and OS's. 

Good point in regards to another LOCAL backup approach...DB admins should 
definitely consider using the backup software that is included with the DB 
product. 
That would fit well in conjunction with the other methods (which would then 
backup these local backups).

The rationale for the multi-method approach is to protect (i.e. CYA) with 
redundancy, using various methods that may be more suitable for zLinux, DB's 
and the z/VM and CMS storage.

WARNING:  To do this reliably, you need software that is capable of 
establishing an I/O consistency group.  If you want to FLASHCOPY the volumes 
and sequentially backup the volume copies, that's ok, but do NOT just 
sequentially copy the live volumes of a running z/VM system.  (If you wouldn't 
do it to a running z/OS system, don't do it to any other system.)  This process 
is intimately tied to your DR strategy, too, so get it right.

If you have databases, use the backup software for the database.  If you're 
using hardware replication, be sure that it's supported by the database vendor.

Some people take a too-casual approach to backups and DR.  I too often hear 
"Don't worry, I'm doing it from z/OS." as though z/OS has magical powers over 
z/VM and Linux.  Don't fall into that trap.  That way there be dragons.

Yes, but there are a few restrictions, provisos, and quid-pro-quos:
1. All PPRCOPY volumes must be dedicated volumes or full-pack minidisks.
2. The managing guest directory entry must contain "STDEVOPT DASDSYS 
DATAMOVER".

As far as IBM DS8000 is concerned, if you have Flashcopy, you also have 
Metro Mirror (PPRC), as both are part of the Copy Services (CS) feature. 
In fact, here are the function in each license type:

Base function License (BF)
? Operating Environment License
? Logical Configuration support for FB (Open Systems)
? Thin Provisioning
? Easy Tier
? I/O Priority Manager

Copy Services License (CS)
? IBM FlashCopy®
? Metro Mirror
? Global Mirror
? Metro/Global Mirror
? z/Global Mirror
? z/Global Mirror Resync
? Multi-Target PPRC

z-Synergy Services License (zsS)
? FICON attachment
? PAV
? HyperPAV
? High-performance FICON (zHPF)
? IBM z/OS Distributed Data Backup

To me, it's simpler and more cost-effective to get GDPS.  The 
configurations include local HA with Hyperswap and flashcopy images (with 
zero data loss and no down time), as well as remote copy (Global Mirror) 
along with flashcopy images to allow DR testing while still maintaining 
local and remote HA.  The important thing is that YOU don't support it. 
(Care and feeding of disk mirrors is not trivial.)

ICKDSF and the CP FLASHCOPY family of commands are the only native 
functions in z/VM that manage Copy Services.  I wish we had Copy Services 
Manager (CSM) for the CMS environment.

Good point.  When I said to use FLASHCOPY, I meant to use the technology, 
not the command.  The CP FLASHCOPY command cannot be used to create a 
multi-volume consistency group.

Maybe we are talking about different things...you can establish

In the ICKDSF manual

Re: zLinux backup solutions

Scott,

You don't need Copy Services Manager, you just need a storage subsystem capable 
and enabled for Global Mirror, which is independent and outside of any 
operating system.  z/VM disks can be part of a consistency group, just as VSE, 
z/OS, Linux or TPF disks can.

While z/VM can't use consistency groups -- z/OS and zLinux can with CSM

we have this running on a zLinux guest to be able to flash with consistency

WARNING:  To do this reliably, you need software that is capable of 
establishing an I/O consistency group.  If you want to FLASHCOPY the 
volumes and sequentially backup the volume copies, that's ok, but do NOT 
just sequentially copy the live volumes of a running z/VM system.  (If you 
wouldn't do it to a running z/OS system, don't do it to any other system.) 
 This process is intimately tied to your DR strategy, too, so get it 
right.

If you have databases, use the backup software for the database.  If 
you're using hardware replication, be sure that it's supported by the 
database vendor.

Some people take a too-casual approach to backups and DR.  I too often 
hear "Don't worry, I'm doing it from z/OS." as though z/OS has magical 
powers over z/VM and Linux.  Don't fall into that trap.  That way there be 
dragons.

Re: zLinux backup solutions

2016-11-10 Thread Ponte, Douglas C. (JMD) 
Hi,



Overall, a 4-tiered approach would be ideal:



o Full volume backups



o Incremental backups



o Local/administrator access backups



o Disaster Recovery mirroring

Fullpack volume backups  can be run daily, weekly and monthly, using JCL 
with automation tools (existing on z/OS already, e.g. BMC Control-M or Tivoli 
Automation). This should be done with all z/VM and zLinux volumes.



In the full volume backup cases, stopping/shutting down is not always 
necessary, albeit it may be good practice to at least quiesce when it comes to 
DB’s and heavy use servers. (e.g. DB2, Oracle, etc)



++

Incremental backups --- should also be done, separately. When performing 
incremental backups, a full volume backup is done first. This also allows for 
full volume restores, from another backup source and/or method. A file or 
filesystem itself can be backed up or restored using previous iterations of 
saved copies.

Tivoli Storage Manager (TSM) is one option that can do this, from IBM.

FDR Upstream is a another option, from Innovation. Similarly, it can  be used 
primarlily for the zLinux filesystems, where the server resides on z/OS.

FDR Upstream Reservoir can be used in place of the z/OS server, which allows 
putting the backups/server on another platform (x86, AIX, SUN, etc.). The 
Reservoir scheme may require tape management for z/VM, so it is recommended to 
use the z/OS server repository (just plain UPSTREAM).

HIDRO, VM:Backup or IBM’s z/VM Backup and Restore Manager…these are good for 
full/minidisk backups, but will NOT be able to backup to the zLinux filesystem 
level, which might not be helpful to you, unless combined with one of the 
products above. However, these two products are very good solutions for z/VM 
minidisks/CMS users.

I think NetBackup can be used this way too, but I have never administered that 
product.

++



Local/manual backup  In the x86 and UNIX world, restoration of files and 
filesystems are done on Linux, AIX and Solaris via NetBackup and Flash Archive 
images (FLAR). Solaris admins state that this method can take hours to recover 
full LDOM images or large filesystems.



There are some other methods that can be relatively crude or even redundant 
(whether manually done or automated) in doing local backups to zLinux 
filesystems. This includes tools like rsync, etc.



However, some centralized solutions are available for zLiunx. For example, with 
RHEL via their RH Satellite server. This also provides a change management 
solution that may be already practiced by x86 RHEL admins, which may be 
helpful. The x86 RHEL sat server admins can carve an organization out for the 
zLinux folks. It would provide better transition for administrators and 
configuration/file migration (if moving applications between platforms). The RH 
Satellite server can provision new RHEL guests and backup all filesystems for 
full image recovery (if needed from another source). Although, this is a good 
solution for file/filesystem level backup, since it can provide multiple 
iterations of files. Therefore, the administrator could logon to the RH 
Satellite server, retrieve and deploy older versions of files. Or they could 
restore filesystems and entire images.



++



Disaster Recovery - also should be addressed. Mirroring can be used to 
easily copy data off-site; for many, this is a commonly used by mid to large 
shops with z/OS and z/VM.

Re: zLinux backup solutions

2016-11-09 Thread Steffen Maier 
[disclaimer: FCP rather than FICON point of view assumed in the 
following so there might be differences]


If your workload could live with an atomically consistent but "dirty" 
disk content, you could use online block device snapshot technologies. 
Maybe inside Linux with LVM snapshot. Storage servers can also do this 
for you without Linux CPU cycles and even more so they can support 
snapshot consistency groups which you need if some filesystem (or raw 
RDBMS table space) spans multiple volumes (such as with LVM striping).


There might be backup software solutions exploiting above, but that's 
beyond my knowledge.


On restarting your workload (such as Linux boot) after a restore of such 
snapshot content, the workload will see some consistent atomic disk 
content, but the content is not clean as in closed application files or 
as in unmounted filesystems. So the application/filesystem (or whatever 
read/writes from/to disks) needs to cope with that, e.g. by replaying a 
journal.


I suppose if you not only collect disk snapshots but before doing so 
suspend the Linux to disk (potentially with hypervisor support), you 
could resume such Linux with those disk snapshots and apps/fs would not 
even notice (because they slept and then wake up with the old state as 
if nothing happened inbetween). Suspending is of course already some 
kind of disruption or temporary outage taking some time as opposed to 
what I mentioned above.
