PX Feature clarification (Snapshots) and Crypto Ransomware

Hello,
I am trying to better understand the "Snapshots" feature of the Lenovo PX2 series NAS devices. I currently have a px2-300d (with latest firmware). I have inquired over the phone, but the person I spoke with did not provide a definitive answer.
I would like my PC workstation backups to be protected from Cryptolocker-like malware, however, we do not want to use a cloud based backup system (which does protect against Crypto Ransomware). As you may know, Cryptolocker, and similar malware, can encrypt, or corrupt, all files acccessible from the PC/workstation, including network backup locations containing backups.
I would like to know if the "Snapshots" feature of the PX2 NAS devices would provide adequate protection against this. Additionally, I would like instructions for properly setting up that feature to provide the necessary protection. If the "Snapshots" feature does not provide protection, I'm looking for other suggestions or solutions to the problem that can be used with these NAS devices.
Thanks, in advance, for your time and help.
Regards,
Bob

Hello ohbobva
With px devices you can manage how much of the storage pool is used for specific tasks.
With a default configuration on a px2 it would be RAID1 across the disks creating a single storage pool. This is the storage pool listed under all features>drive management.
The portion of the storage pool that is blue is allocated, the white portion is unallocated.
Under the storage pool name there will be a "Volumes" section, this will list the different typs of volumes that are using the allocated space.
The default is a share volume and usually a portion of the storage pool is allocated (reserved) for that volume's use. iSCSI LUNs(drives) and Snapshots would be other types of volumes that can allocate(reserve) the storage pools unallocated space
If you have a share volume that you want to use snapshots with and it is 2TB in size you would want to allow 2 TB of unallocated space to be available when setting up the Snapshot.
With what your are trying to do, having a 45/45/10 allocation would be best. 45% of the storage pool allocated for the Share volume, 45% for the Snapshots, and 10% left unallocated for the firmware to maintain the storage pool and volumes efficiently.
Again this should not be consided a backup, but more of a volume level fault tolerance.

CDC feature for snapshots and views

Hi,
Can we use the Oracle Change Data Capture (CDC) feature which can be used with Oracle's Publish and Subscribe packages for views and snapshots in Oracle 10g? Or is it only for tables?

This is question for Oracle support as DI is just using it. And they will tell you that it is for tables only.

Cloning a ZFS rooted zone does a copy rather than snapshot and clone?

Solaris 10 05/08 and 10/08 on SPARC
When I clone an existing zone that is stored on a ZFS filesystem the system creates a copy rather than take a ZFS snapshot and clone as the documentation suggests;
Using ZFS to Clone Non-Global Zones and Other Enhancements
Solaris 10 6/06 Release: When the source zonepath and the target zonepath both reside on ZFS and are in the same pool,
zoneadm clone now automatically uses the ZFS clone feature to clone a zone. This enhancement means that zoneadm
clone will take a ZFS snapshot of the source zonepath and set up the target zonepathCurrently I have a ZFS root pool for the global zone, the boot environment is s10u6;
rpool 10.4G 56.5G 94K /rpool
rpool/ROOT 7.39G 56.5G 18K legacy
rpool/ROOT/s10u6 7.39G 56.5G 6.57G /
rpool/ROOT/s10u6/zones 844M 56.5G 27K /zones
rpool/ROOT/s10u6/zones/moetutil 844M 56.5G 844M /zones/moetutil
My first zone is called moetutil and is up and running. I create a new zone ready to clone the original one;
-bash-3.00# zonecfg -z newzone 'create; set autoboot=true; set zonepath=/zones/newzone; add net; set address=192.168.0.10; set physical=ce0; end; verify; commit; exit'
-bash-3.00# zoneadm list -vc
ID NAME STATUS PATH BRAND IP
0 global running / native shared
- moetutil installed /zones/moetutil native shared
- newzone configured /zones/newzone native shared
Now I clone it;
-bash-3.00# zoneadm -z newzone clone moetutil
Cloning zonepath /zones/moetutil...
I'm expecting to see;
-bash-3.00# zoneadm -z newzone clone moetutil
Cloning snapshot rpool/ROOT/s10u6/zones/moetutil@SUNWzone1
Instead of copying, a ZFS clone has been created for this zone.
What am I missing?
Thanks
Mark

Hi Mark,
Sorry, I don't have an answer but I'm seeing the exact same behavior - also with S10u6. Please let me know if you get an answer.
Thanks!

Backpac: A package state snapshot and restore tool for Arch Linux

backpac:
A package state snapshot and restore tool for Arch Linux with config file save/restore support.
https://aur.archlinux.org/packages.php?ID=52957
https://github.com/altercation/backpac (see readme on the github repository for more information)
Summary & Features
It's a common method of setting up a single system: take some notes about what packages you've installed, what files you've modified.
Backpac creates those notes for you and helps back up important configuration files. Specifically, backpac does the following:
maintains a list of installed groups (based on 80% of group packages being installed)
maintains a list of packages (including official and aur packages, listed separately)
maintains a list of files (manually created)
backs up key config files as detailed in the files list you create
The package, group and files lists along with the snapshot config files allows system state to be easily committed to version control such as git.
Backpac can also use these lists to install packages and files. Essentially, then, backpac takes a snapshot of your system and can recreate that state from the files and lists it archives.
Use Cases
Ongoing system state backup to github
Quick install of new system from existing backpac config
Conform current system to given state in backpac config
Backpac is a very, very lightweight way of saving and restoring system state.
It's not intended for rolling out and maintaining multiple similar systems, it's designed to assist individual users in the maintainance of their own Arch Linux box.
Status
Alpha, release for testing among those interested. Passing all tests right now but will continue to rework and refine. Bug reports needed.
Why?
There are a lot of 'big-iron' solutions to maintaining, backing up and restoring system state. Setting these up for a single system or a handful of personal systems has always seemed like overkill.
There are also some existing pacman list making utilities around, but most of them seem to list either all packages or don't separate the official and aur packages the way I wanted. Some detect group install state, some don't. I wanted all these features in backpac.
Finally, whatever tool I use, I'd like it to be simple (c.f. the Arch Way). Lists that are produced should be human readable, human maintainable and not different from what I'm using in non-automated form. Backpac fulfills these requirements.
Regarding files, I wanted to be able to backup arbitrary system files to a git repository. Tools like etckeeper are interesting but non /etc files in that case aren't backed up (without some link trickery) and there isn't any automatic integration with pacman, so there is no current advantage to using a tool like that. I also like making an explicit list of files to snapshot.
Sample Output
This is the command line report. Additionally, backpac saves this information to the backpac groups, packages and files lists and the files snapshot directory.
$ backpac -Qf
backpac

If AUR_HELPER is defined by the user, then either you might need a list of major AUR helpers and their command line switches so you can pick the correct switch for what needs to be done (most use some variation of -S for installing, but not all), or have the user define the correct switch(es) somehow for their chosen AUR helper.
That's a good idea. I'll add that to my AUR refactoring todo.
I also found directory tracking to be a weakness in other dotfile managers that I tried. I think you would definitely have to recursively list out the contents of a tracked directory and deal with each file individually. Wildcard support would be nice...I just haven't personally found a use case for it yet.
I've been thinking that I could just add the directory and scan through it for any non-default attribute files. If those are found then they get automatically added to the files list. That's pretty close to what etckeeper does.
Edit: I just compiled the dev version and removed my comments for already fixed things...sorry!
The master branch should have those fixes as well, but I didn't update the version number in the package build. I'll have to do that.
1. Still apparently didn't handle the escaped space for this item: (the file does exist on my system)
Ok, good to know. This wildcard directory business will require some new code and refactoring so I'll also rework my filenames handling.
2. Suggestion: you should make that awesome README into a man page!
I was working on one (the pkgbuild has a commented out line for the man page) but I had to leave it for later. Definitely want a man page. Once this stabilizes and I'm sure there aren't any big structural changes, I'll convert it to man format.
3. Suggestion: add the word 'dotfile' into your description somewhere on this page, the github page, and in the package description so people looking for dotfile managers will find it. You could also consider modularizing the script into a dotfile manager and the package manager, so people on other distros could take advantage of your dotfile management scheme.
I actually have a different script for dotfile management that doesn't touch packages, but there is definitely overlap with this one. That script isn't released yet, though, and if people find this useful for dotfile management that's great. I'll add that in.
4. Suggestion: since -Q is a read-only operation, why not just make it run with -f automatically to avoid the prompt?
Originally, running backpac without any command line options produced the Query output. I was concerned that since it is a utility that can potentially overwrite system files, it is important to give users a clear statement prior to execution about what will be done. Since the Query output is essentially the same as the Update and System reports in format and content, I wanted to be explicit about the Query being a passive no-change operation. The current command line options aren't set in stone though. If you feel strongly about it being different, let me know.
Long answer to a short question
5. Another suggestion: any thought to providing some sort of 'scrub' function to remove private information from the stored files if desired? This would be cool for publishing public dotfiles to github. Perhaps a credentials file (I did this with python for my own configs). Probably detecting email addresses and passwords without a scrub file would be rather difficult because dotfiles come in so many flavors.
Yes, absolutely. In fact, if you look at the lib/local file (pretty sure it's in both master and dev branches in this state) you'll see some references to a sanitize function. The idea there is that the user will list out bash associative arrays like this:
SANITIZE_WPA_=(
[FILE]='/etc/wpa_supplicant.conf'
[CMD]='sed s/expungepattern/sanitizedoutput/g'
Question: am I missing an obvious option to remove a file from the files.d directory if I delete it from the files list? Or do I have to delete it manually? It might be helpful to add a section to the README on how to update and delete dotfiles from being tracked, and also a more detailed description of what the -b option does (and what is actually created when it's not used).
You are only missing the function I didn't finish. There should be either dummy code or a TODO in the backpac main script referencing garbage collection, which isn't difficult but I just haven't finished it. The idea being another loop of "hey I found these old files in your files.d, mind if I delete them?" It's on my list and I'll try to get it in asap.
And finally, just out of curiosity, why did you choose to actually copy the files instead of symlink like so many other dotfile managers do?
git not following symlinks, hardlinks also out for permissions issues (git wouldn't be able to read the files, change them, etc.)
I definitely would prefer to not make an entire copy of the file, but I haven't come up with a better option. Shout with ideas, though. Also, if there is a way around the link issues I noted above, let me know. I don't see one but that doesn't mean it's not there.
edit: I think a Seattle area Arch meetup would be cool! Perhaps coffee someplace? Bellevue? U-district? Anyone else? BYOPOL (bring your own pimped out laptop)
A general meetup sounds good. I was also thinking it would be fun to do a mini archcon with some demos.

The future of Snapshot, and similar tools.

My apologies for posting this twice. I posted it first as a follow up
to an old thread in ...
novell.support.zenworks.desktop-management.6x.install-setup
I am quoting some comments made in that forum.
Then after surfing the forums for awhile, I thought the issue might get
more attention, if I posted it here. I am looking for ideas and advice
on the future of snap shot, and any tools that Novell might provide to
replace it.
If I could address some of these comments, in hopes of better
understanding ...
RE: >>>

Admin Studio is not cheap. After a client has spend thousands of
dollars to implement ZENWorks, now I have to tell them to drop another
couple thousand down for an application packager. I also don't fully
understand Novell's relationship with the product, they don't seem to be
partnering well together, I'd appreciate anyone else's read on this
relationship.
RE: >>
> Novell has for over 5 years now been trying to steer people from
> Snapshot
I've heard that statement made verbally by many engineers, but I don't
always see the practice following that.
Has Novell ever gone on record to state they will no longer support snap
shot???
RE: >> > If your snapshots are failing with the latest versions of
snapshot, then

> snapshot should be trying to handle.
Maybe I've just gotten lucky? I've have not had many issues with using
snapshot, and I have been involved in a wide variety of applications.
I have seen the statement made on the forum that ZEN Works is not really
a "Packaging" suite. While that may be a true statement, because
Snapshot has been packaged with the product for so long, the mind set of
customers is that it is expected to work, and be supported.
I look forward to additional comments on this matter.

Tom,
I'm not sure what exactly are you searching for? ZdM is already providing
you with snapshot replacement - AdminStudio ZfD edition, included in ZfD
price.
AdminStudio part for preparing snapshot MSI is identical in ZfD and
Professional edition.
All comments you qouted (including this one) are personal opinions - I
suggest you to try AdminStudio ZfD edition and make your own.

HT5824 I've been using numbers for iPad and I accidentally deleted a column. And the auto-save feature saved that and now I can't undo it. Does iCloud storage have backups of saved files from like 10 minutes ago? I have number

I've been using numbers for iPad and I accidentally deleted a column. And the auto-save feature saved that and now I can't undo it. Does iCloud storage have backups of saved files from like 10 minutes ago? I have numbers synced to iCloud.
I tried to undo it but the app crashed.
I am hoping there's like a previously saved version of my file in iCloud somewhere.

No, iOS does not do short term incremental back ups to iCloud such as you get with Time Capsule.It backs up when you do soo manually, or if set properly, when the device is plugged in and connected to WiFi. It will not have saved your changes as of 10 minutes prior.

SQL Server 2008 R2 Replication - not applying snapshot and not updating all repliacted columns

We are using transactional replicating on SQL Server 2008 R2 (SP1) using a remote distributor. We are replicating from BaanLN, which is an ERP application to up to 5 subscribers, all using push publications.
Tables can range from a couple million rows to 12 million rows and 100's of GBs in size.
And it's due to the size of the tables that it was designed with a one publisher to one table architecture.
Until recently it has been working very smooth (last four years)) but we have come across two issues I have never encountered.
While this has happen a half dozen times before, it last occurred a couple weeks ago when I was adding three new publications, again a one table per publication architecture.
We use standard SS repl proc calls to create the publications, which have been successful for years.
On this occasion replication created the three publications, assigned the subscribers and even generated the new snapshot for all three new publications.
However, while it appeared that replication had created all the publications correctly from end to end, it actually only applied one of the three snapshot and created the new table on both of the new subscribers (two on each of the
publications). It only applied the snapshot to one of the two subscribers for the second publications, and did not apply to any on the third.
I let it run for three hours to see if it was a back log issue.
Replication was showing commands coming across when looking at the sync verification at the publisher and
it would even successfully pass a tracer token through each of the three new publications, despite there not being tables on either subscriber on one of the publishers and missing on one of the subscribers on another.
I ended up attempting to reinitialize roughly a dozen times, spanning a day, and one of the two remaining publications was correctly reinitialized and the snapshot applied, but the second of the two (failed) again had the same mysterious result, and
again looked like it was successful based on all the monitoring.
So I kept reinitializing the last and after multiple attempts spanning a day, it too finally was built correctly.
Now the story only get a little stranger. We just found out yesterday that on Friday the 17th
at 7:45, the approximate time started the aforementioned deployment of the three new publications,
we also had three transaction from a stable and vetted publication send over all changes except for a single status column.
This publication has 12 million rows and is very active, with thousands of changes daily.
, The three rows did not replicate a status change from a 5 to a 6.
We verified that the status was in fact 6 on the publisher, and
5 on both subscribers, yet no messages or errors. All the other rows successfully updated.
We fixed it by updating the publication from 6 back to 5 then back to 6 again on those specific rows and it worked.
The CPU is low and overall latency is minimal on the distributor.
From all accounts the replication is stable and smooth, but very busy.
The issues above have only recently started. I am not sure where to look for a problem, and to that end, a solution.

I suspect the problem with the new publication/subscriptions not initializing may have been a result of timeouts but it is hard to say for sure. The fact that it eventually succeeded after multiple attempts leads me to believe this. If this happens
again, enable verbose agent logging for the Distribution Agent to see if you are getting query timeouts. Add the parameters
-OutputVerboseLevel 2 -Output C:\TEMP\DistributionAgent.log to the Distribution Agent Run Agent job step, rerun the agent, and collect the log.
If you are getting query timeouts, try increasing the Distribution Agent -QueryTimeOut parameter. The default is 1800 seconds. Try bumping this up to 3600 seconds.
Regarding the three transactions not replicating, inspect MSrepl_errors in the distribution database for the time these transactions occurred and see if any errors occurred.

How do I download all my photos onto an external hard drive intact without loosing iPhoto's features, important info and details? I need to delete pictures and files to make room in My mac's memory which is currently full.

Hi
How do I download all my photos onto an external hard drive intact without loosing iPhoto's features, important info and details? I need to delete pictures and files to make room in My mac's memory which is currently full.
Maro

So you want to move the iPhoto Library?
Make sure the drive is formatted Mac OS Extended (Journaled)
1. Quit iPhoto
2. Copy the iPhoto Library from your Pictures Folder to the External Disk.
3. Hold down the option (or alt) key while launching iPhoto. From the resulting menu select 'Choose Library' and navigate to the new location. From that point on this will be the default location of your library.
4. Test the library and when you're sure all is well, trash the one on your internal HD to free up space.

Snapshot and backup

Hello BW Experts,
Current Scenario:
There is a daily snapshot of the BW system in nite for our Production server. During this they have to stop any jobs / loads running at that time.
Secondly they take a backup every weekend. They stop any jobs / loads during that time also.
Wondering if you could provide ur experiences, that would very great of you..
1) Is snapshot necessary every day?
2) what is the alternative to daily snapshot?
3) what is the best procedure for daily snapshot ?
4) is there a procedure not to stop the loads / jobs during snapshot ?
5) Is backup necessary every weekend?
6) what is the alternative to weekly backup?
7) what is the best procedure for weekly backup ?
8) is there a procedure not to stop the loads / jobs during backup ?
9) is there any doc / paper / link / notes for the snapshots and backups for BW production system.
10)what is the typical time taken for snapshot?
11) what is the typical time taken for backup ?
any does please mail to [email protected]
Thanks,
BWer

Thanks for the valuable info Mimosa.
In our company, they call the snapshot: copy of the production box to the box on the SAN network. The copy is made to the disc. Here the snapshot disc is on RAID 0 and production disc is on RAID 5. They do this every night.
In our company backup is : taking copy to the tape. they do this every weekend.
Its interesting that they do the 'split mirror on-line backup' daily during system is available to all users & jobs. Wondering if you have any details of this backup. What is the procedure called. What level is this copy done, on the database level, network functionality or sap functionality.....?
Suggestions appreciated.
Thanks,
BWer

How to Export Snapshots and Materlized View in Oracle 9i

Hi,
How to Export Snapshots and Materlized View in Oracle 9i .
I require to Migrate from 9i to 10g with either Export or Script.
Please help

Using exp-imp for snapshots generally causes problems, at least for me. I would prefer taking their creation scripts and running them on the new database.
By the way, what do you mean by "migrate from 9i to 10g"? Are you trying to create the same snapshots in another (10g) database or are you trying to upgrade your 9i database to 10g? If it is the latter then you can just upgrade the database automatically with the upgrade assistant or manually using upgrade scripts.

Remove calling features - Answer 1571 and Privacy ...

I've just ordered a new connection, and decided to opt into the "free" calling features Answer 1571 and Privacy at Home. After completing the order I was notified by email that these features are only free under certain conditions, otherwise there's an additional monthly charge. This was probably mentioned somewhere while I was ordering it, but I didn't see it so I'm guessing it was buried in small print.
I'd like to opt out of these calling features to avoid having to pay any additional charges, but I can't find any information on how to change which calling features I'm subscribed to. Please can you let me know how to turn off Answer 1571 and Privacy at Home.
I'd also like to make a suggestion: You should make it clear to your customers that there are hidden charges associated with these "free" services before they place their orders.
-Mike

You may be able to visit www.bt.com/myaccount. there is a link on there to changing your calling features, if not it's a call to 150

Does SAP use SQL server's snapshot and transactional replication?

Could you help with this?
Does SAP use SQL server's snapshot and transactional replication?
Thanks!

Hi Christy,
no, SAP does not directly leverage these functions.
But none the less, it is up to you to use these on your system. I regulary use the snapshot functionality when applying Support Packages. In case somehing goes wrong a snapshot is the easiest way to roll back the import process (not exactly the best choice when talking about production and users keep on working while importing).
Have a look at this [document |http://download.microsoft.com/download/d/9/4/d948f981-926e-40fa-a026-5bfcf076d9b9/SAP_SQL2005_Best Practices.doc]. It deals with Best Practices and also covers snapshot, replication and mirroring.

data : iatb like bdcmsgcol,
Loop at itab.
Write : itab-msgty, itab-messg1.
endloop.
those having msgty as S are success and those having E are the records not updated.
