Seeking advice for backing up Xserve G5 w/ RAID PCI card

Hello all!
I'm a newbie to Macs and server admin, and I have inherited the job of setting up a server at work for file storage. I'll do my best to give a concise description of our set-up - I'm looking for some advice on the last few odds and ends... mainly how we can backup the system.
We bought an Xserve G5 with an option RAID PCI card. We have 3 500GB drives in the Xserve, configured to RAID 5 (giving us effectively 1TB of storage space). We will be using the server for data storage. About 20 computers will access the server over a network; we are using an assortment of Macs and PCS.
I am seeking advice on backup systems for the server. In the event that the RAID5 fails, we don't want to lose our data. We just need a snapshot of the server; we don't need to archive data or to take the HD offsite. Our old server just used Retrospect to run incremental backups every night (with a complete clean backup once a month). Our current thought is to attach large external hard drive to our admin computer (not the server directly) and run nightly backups as before.
The major points I have are:
-Any thoughts on reliable 1 TB external drives?
-Any recommendations on software that can backup from a RAID over a network? I found info for Retrospect Server 6.0 - it seems to do what we want, but is rather pricey.
Thanks in advance for any advice! I really appreciate it!

Greetings-
We all started out as newbies at one time or another-no worries. That is why we are here.
I personally use the Lacie branded drives. They are sturdy and reliable. My only thoughts here are to have at least three external drives-one for today's backup, one for a backup stored securely nearby, and one to be securely stored off-site. Rotate the drives daily so that your worst-case scenario will be a catastrophe that requires you to use a three-day old backup, depending upon how old your off-site backup is. Not ideal but better than the alternative. External drives are cheap enough these days to allow you to do this at a reasonable cost. Plus it is easy enough to throw one in a briefcase and tote it home for safety (just don't lose it!)
I would stay away from Retrospect. If you search these forums you will find several instances of folks having some serious issues with the program. I use a program called Carbon Copy Cloner that does the job nicely for my basement server. There are ways to do the backups via the command line interface as well but I am not so familiar with those commands. You may have to dig a little deeper to find something that works for you.
One of the other advantages of the FW external drive is that you can share it with other users, so perhaps you can set things up to have your network backups to go to that drive. Tis a thought.
Luck-

Advice for backing up

I need some advice on backing up
I don't want to use time machine because i dont need regular back-ups, i just need a program that will backup everything on my macintosh HD to my external hard drive once every 2 weeks or so
any suggestions?

So you're perfectly happy losing as much as two weeks of work when (not if) your HD fails, or some other major failure happens?
As Malcom says, you can still use Time Machine. Another way is to turn it off in TM > Preferences, then when you want to do a backup, use the +Back Up Now+ option from the TM icon in your Menubar, or control-clicking (right-clicking) the TM icon in your Dock.

Seeking Help for Guidance in developing a product using JAVA CARD

Hi All,
I am using windows environment with netbeans 6.8 as developer tool and MySql Server connectivity for back end process.My requirement is to develop applets and installing them to my Smart card and reader.my question is
1. how i am supposed to create applets to get the student id of particular student whose id is already registered in the database?
2. how to install them into the smart card?
3.what are the commands i am supposed to follow if other than APDU commands?
4.i found there is APDU commands but what do that each CLA,INS,p1,p2,Lc,le..commands used for?how can i use them in my creation of applets.i found the command varies for certain requirements.
5.if possible please help me with a small example so that i will start developing it.
can anyone help me in developing this application.i will be so helpful if anyone helps me in guiding me to develop the java card product.

Hi,
Welcome to the wonderful world of embedded Java development!
Sijukj wrote:
1. how i am supposed to create applets to get the student id of particular student whose id is already registered in the database?The first step is to download the Java Card Development Kit (JCDK) from the Sun website (along with the related documentation/specifications). If you plan on using your code on a real card, I would recommend JC version 2.2.1 or 2.2.2. If it is sufficient to run your applet on a simulator (as a proof of concept or for assignments) with no intention on running on real hardware you could go for JC 3.0.2 and use the supplied simulator. This version of JC does not have commercially available cards as of yet.
Once you have the applet coded and installed on your card, you would personalise the card for the card holder. This means loading card holder specific data into your application. This may also involve registering the smart card ID with the student in your database.
2. how to install them into the smart card?The procedure for loading and installing applets is outlined in the Java Card documentation (available with the JC development kits from Sun) and the GlobalPlatform card specifications (available from [http://www.globalplatform.org]). You can look into some open source tools for doing this (GPShell and the Java Card Development Kit).
3.what are the commands i am supposed to follow if other than APDU commands?This depends on what you are trying to achieve with your applet. If you want interoperability you could implement a standard like ISO7816 or IOS24727. This is a lot of work so you may just want to implement the proprietary you require for each operation you need (e.g. set student ID, get student ID etc).
4.i found there is APDU commands but what do that each CLA,INS,p1,p2,Lc,le..commands used for?how can i use them in my creation of applets.i found the command varies for certain requirements.These are defined in ISO7816 part 4.
The CLA byte gives information on the command you are sending such as secure messaging, command chaining, ISO or proprietary command
The INS is the instruction or command you are trying to perform
P1 and P2 are parameters to the command. These may not be required for each command but are able to be used to convey further information to the applet.
Lc is the length of the data field you are sending (e.g. for a PUT DATA command this would be the amount of data you are sending)
Le is the length of the data you expect to receive back from the card. If this is absent you do not expect the card to return any data, 0x00 means send all the data you have left (up to the limit of the response APDU)
5.if possible please help me with a small example so that i will start developing it.You can find example code in the Java Card Development Kit. There are a wide range of examples there that can help you get started.
Cheers,
Shane

In need of advice for backing up HD Video

So we returned from a vacation,
where I shot all the video in HD 1080p.
We got back, and I used Final Cut Express to convert the AVCHD files from .mkv to .mov files.
All together, the total files come to a whopping 78.93 GB. Wow.
I need to back these up to DVD's or something
(My wife says she doesnt want them on an external hard drive, her last one died)
is there a way I could compress these?
or should I use quicktime/visualhub to bring down the quality a little?
any advice would be greatly appreciated
thanks

Solutions:
1) ignore the wife and backup to a good hard drive such as a LaCie quadra. usb or firewire.
2) Buy Time Capsule and backup to it.
3) what would i do? Use MPEGStreamClip to make mp4 files , to control the file size. The picture will still look very good but it does not do 5.1 channel sound. Handbrake does but since the file is HD probably will crash while encoding so will VisualHub. Another consideration, MPEGStreamClip on a 2 gig HD movie will take 15 hrs on a Mac pro let alone an iMac.
Currently not too many programs will do HD encoding.
4) backup to optical disc, I'd never do that ; too many compatibilty issues with different drives perceived for future usage.
5) back to the wife, user should alway have three backup stategies; ie main drive then backup # 1 then backup #2. I've backup to external and internal hard drives for over a decade without problems.

Need advice for XRaid and Xserve configuration

Hi,
sorry for my perhaps dumb question but I am new to XServe RAID and did not find an answer to my problem by searching the forum.
In my (university) department we will change our complete server infrastructure this year and I could persuade my colleagues to consider to switch to apple hardware.
Now the point is that the server installation should be redundant. Thus I would purchase two XServes and set them up as described in the "High Availability Admin" guide on the support pages of OS X Server. As data storage there would be a XServe RAID but the problem is that as I read in this forum you can attach it to only one server without additional equipment. That would mean that in a failure case it would be necessary that someone disconnects the fibre channel cables and plugs them into the second server acting as fail back -> no good.
Then I read about XSan but noticed that you need one (or better two!) additional servers for metadata. As the solution must not cost too much and there is no real need to access data from more than one server at the same time the XSan solution would be real overkill.
So next is a comment I found that it would be possible to use the fibre net switch to make this switching from the failed server to the backup one. Do all fibre switches support this option? How much do those cost? The only machines that would be connected are one XRaid with two cables and two XServes resulting in 4 needed ports.
Of course all different suggestions are welcome!

Thanks for the answers!
The first tip is interesting (and somewhat pricely more affordable). Unfortunately in a failure case by using the synced RAID there would be some data inconsistencies as the sync process would be made only in certain time intervals, e.g. every hour. When the primary server and its copy of the RAID comes back online there would be the problem to determine which copy of a file is to be kept.
To avoid this problem the time interval of the rsync could be shortened but how much process load does a nearly constant (lets say every minute rsync produce? The network load is not the problem as data could be transferred through the dedicated firewire connection between the two Xserves that is used for IP failover.
The second tip is what I had in mind. As right now I have to fiddle around with several linux servers I am not new to CLI so I will find out how to realize that. If not I will give the consulting team a try.
Are there certain FC switches that can be recommended or a certain brand? Primarily it should be low cost.

Parsing XML with Java - seeking advice for method to pursue

Hi guys
So here's the deal: I want to parse some XML from a server, get all the data I need from it, then shunt that data to the classes that need it. However, I'm really not sure what the best way of parsing the XML is.
I've just written a class for obtaining the file, and one for building a DOM from the XML file. But looking at org.w3c.dom in the Java API documentation (see HERE) I'll have to implement shedloads of interfaces to be able to take advantage of the DOM, and I don't even know a lot about it.
So am I best just writing a simple parser based on regular expressions to get the data I want? There's about 5 attributes in the XML file that I need to get - 5 for each instance of the containing element. So I don't think it'll be hard to do with regular expressions.. plus even if I did decide to implement all the DOM interfaces, the only way I'd know how to do half the stuff is with regular expressions anyway. I mean, how else would you do it? How else could you match up Nodes according to the Strings you're using for the elements, attributes etc?
I worry that a parser using regular expressions might be too slow... I'm building this as an applet to visually display information from the server. I have nothing to support those fears, I'm just not experienced enough to know whether speed would be a problem if I chose this route... I don't think it would, but really need confirmation of that suspicion being unfounded.
Any advice would be very, very welcome, as I'm tearing my hair out at the moment, unsure what to do.

Komodo wrote:But JDOM is not in the core class libraries, is it? So if I want to create an applet embedded into a website, am I able to get people to download that as well?
Sorry, I don't know anything about applets.
Komodo wrote:Everyone's advice is appreciated, but my core question remains unanswered - would using regular expressions, considering how simple and unchanging the XML files are, be a viable option in terms of speed?
Yes! I've done more than my fair share of XML processing with REs. It's not always easy. I often wish I could just use something XPath-like. But it's certainly easy to do and would probably mean that you'd have something up and running quicker than if you spent time investigating pure XML parsing approaches.

Seeking advice for a self-teaching programme of new Java techs

Hello,
after a few years of technically poor projects (I learnt a lot in terms of process, quality, and non-Java technologies, by the way), I'd like to catch up with mainstream Java development.
I am preparing a programme to learn a few technologies I have missed over the past years. I plan to develop a couple of utilities (simple CRUD apps) on my spare time, gradually including bits and bits of the bricks I want to grasp.
I need some advice though to make this learning effective.
My first priority is to invest in reusable knowledge, so I will stick to "standard" bricks, and will aim mostly at off-the-shelf tools that work out of the box
(for example, I don't want to spend hours to fix a DB install&configuration issue, as I know I will probably never be paid for that kind of job).
Specifically, the technologies I plan to embrace are:
* Java SE 5 and 6
* jUnit 4
* Spring
* EJB 3 & JPA
* Web UIs
Here are the points where you might help me:
* JDK 1.5 vs 1.6
No real doubt here, the biggest language gap was introduced by 1.5. If I'm correct, 1.6 essentially brings new APIs; as long as those APIs are not my primary target (I'll try them only after I've completed my first round of catch-up :o), I am not missing much language-wise, am I correct?
I could also jump directly to 1.6, ignoring its new APIs, and concentrate on
1.5 language features, but the risk is stability (losing time with a 1.6 beta bug).
* jUnit 4
Nothing special, except I have practically read nothing about it on these forums (contrast this with TSS, where there are regular threads disputing the relative merits of jUnit vs TestNG).
Is v4.0 a non-event? It seems to bring some niceties (mark test components using annotations), but how much comfort did it bring to those of you who have used it over jUnit 3.8.1?
* Spring
Leaving aside that it's on my must-do list, I actually wonder which version I should try?
I also feel I should try it first on a non-EJB app, to avoid mixing concerns. I will skip the JDBC wrapping API though, as I already have a lot to do with other persistance APIs.
Any feedback?
* EJB3/JPA
(I formerly worked with generation 2.1 of the EE specs)
1) The biggest issue here is to find a reliable EJB3 container.
* I've heard JBoss is EJB3-ready, but I don't think it's certified yet.
* Project GlassFish (Sun-driven open-source JEE5 container) is still in the making
* Sun SASP9 is, well, released, but I don't know how much of JEE it supports, and haven't investigated into the licensing details yet
Any feedback on what you're using as a JEE5 container?
2) As far as EJB vs JPA goes, I also have the plan to use the persistence API
outside of EJB (likely, I will develop the same simple CRUD app twice,
once as a Webapp and once as as Swing app, both over the same DB schema).
But maybe this is pointless, as the entity annotations and API are agnostic; have you experienced some difference that deserve thorough learning?
3) Obviously I will need a DB. If the EJB container includes one, fine, at least for the EJB part, otherwise I'll need to install and configure one, that will need to run on a desktop PC on MS WIndows, and preferrably include a handy SQL client console for manual verification.
I know enough of SQL to build even a sub-optimal application schema. However I know nothing of a DB administration, and I don't want to invest in that direction.
Any advice as to a simple off-the-shelf free DB that runs on Windows?
* Web UIs
The dilmena here is two-fold:
1) In term of "view" technology, I hesitate between plain JSP and JSF
If I understand correctly, JSF is a specification for reusable view components.
My local job market leaves me no oportunity to be a UI component developer, whereas I am more likely to someday be tasked to integrate 3rd-party UI components into a business project.
Is my surface understanding of JSF correct? In this case, how much of JSF should I know if I don't have to develop JSF components?
2) In terms of controller, as part of my Spring learning, I'll probably have a look into Spring MVC.
My question is, how much of the servlet/JSP API does springMVC show/hide?
Is it a good idea to use springMVC to learn servlets and JSPs, or should I stick to manual servlet+JSP?
I should add that I've worked with servlets/JSPs formerly (as of J2EE 2 or 3),
I only need to dig new servlet/JSP features.

Seeking advice for a wookiee video person...

I'm shooting alot of videos lately. Typically - they just sit in a folder when I transfer via usb to my dell laptop (sorry I don't have a Macbook pro quite yet!).
I know there is Windows Movie Maker and some other "free" junk out there.
I see Camtasia looks pretty fabulous - but I think all I need is something simple to basicaly do minor editing and then compressing and prepping to share via the internet in various ways with family and friends.
Would QuickTime Pro give me all I need or should l look at buying both QuickTime Pro AND Compressor 4?
(Assuming these are both available for Windows 7).
Any advice would be appreciated.
Thanks,
David Murphy

Compressor is Mac only
QT Pro will only act as a cut editor so hardly the application for you, there is no transitions, titles sound mixing or effects.
Adobe Premier Elementsis fantastic value for money for Windows machines if you plan to do decent hobbyist editing. Look at the website here:

Advice for backing up media - Blu Ray? Anyone try it?

I am currently using external drives to back up lots of video and was wondering if anyone has tried using a Blu Ray burner to do this? Not sure what the data limitations of the disk are? Are there external ones? Would you recommend it or wait a bit longer?
Thanks.

Absolutely, original tapes, along with a project in which they've been properly logged and captured, are the best form of backup.
But not everyone works with DV sources, and not all of our source material is batch-re-capturable.
For instance, I work with an agency that reps touring bands, and a lot of the source material I get is on DVD video. I have to rip and extract the video (to which the clients hold the rights) and import it. At this point, whiile I could theoretically repeat this procedure and get a file almost identical, it still isn't frame accurate and would require some reworking to rebuild any project if teh media were lost.
I agree Blu-ray isn't cost-effective yet per GB, and DVD-5 requires a lot of time and patience to archive. But it's still a good, safe way to back up material like this, IMHO. To steal Shane's example, drop a DVD and a hard drive from a foot off the ground and see which still works. I do archive to hard drives to keep things accessible, but I know too well how vulnerable that storage medium is to failure.
my two cents.

Seeking advice for mirroring systems

Hi all. I'm working on a documentary. Here's the set-up: main editor works on computer connected to full-res versions of footage. She passes sequences off to an assistant, who reconnects them on a second computer to low-res copies of the same footage, works on the sequences and passes them back to the main editor.
Reconnecting never seems to go right. FC invariably has trouble finding certain clips, even though the names are identical for the low-res and high res versions. There is no logic that we can discern for which clips FC will find and which clips it won't. Sometimes it misses whole groups of clips, and sometimes it finds one clip in the group, and not the others, at least not by itself, and we have to manually find and connect each one, one by one, which takes a long time and is extremely tedious.
Obviously our set-up is not ideal, but we're stuck with it, and we'd like to make it work better. So I was wondering if someone could give me some tips, or point me to an article, on how to make the reconnecting process more efficient. I've noticed, for example, that FC is more likely to miss clips that are stored at the end of a series of sub-folders, so we've cutback on folders. Any other changes we should make?

Trying to understand more of your question;
Sounds like two different computers with FC? Accessing the same Media? But at different times? To do two different functions?
In general, yes I agree connecting, or reconnecting Media can be a crap shot. Technically you're supposed to be able to get a good connection process going by asking/choosing to connect all the other related Media which may have the same file path.
But with what ever you're trying to do, it's not working.
And in general, I've found that using Media Manager to re-connect/re-organize all that media can be helpful somtimes. For me, it put all the media that I may have had in several dozen folders all into ONE. This may or may not be helpful, but after using Media Manager, I'm able to open the new project without any media connection problems.
One other thought, perhaps try 'RENAMING' the sequences in each FC editor, so they're not the same.

Seeking advice for a scenario

Hi everyone I am currently a student pursuring my CCNA and one of the things we need to do is a case study. What I've got is a building that is going to use 3 subnets out of a given address space of 192.168.100.0/24. Looking for advice on what router (or routers if more than 1 would be better) would work best for this situation.

Beside the information provided in the other posts, for basic routing, L3 switches and routers often do much the same. However, the former tend to be able to provide much higher level of performance, the latter additional features. Sometimes, especially with the non-chassis platforms, you might need to use both device kinds to obtain both (LAN) performance and (WAN) features.
For example, your 3825 (350 Kpps) could struggle to route 100 Mbps of traffic, where even the smallest (8 port) 3560 (2.7 Mpps) handles much more. Yet, the 3825 supports various interface types, NAT, firewall features, advanced QoS, VPN, etc., while the 3560 doesn't.

Seeking advice for a nagging BT related issue

Dear Forum,
I would appreciate your advice on a performance issue related to using the BT SW stack.
*Some information*:
Non-Toshiba notebook, Intel dual core @ 1.2 GHz, 2 GB RAM, running WinXP pro (5.1.2600 SP2 Build 2600), all MS updates, company computer, MS Office 2003. I got the PC two months ago and separately purchased the 'Wireless 360' internal Bluetooth USB module (Toshiba device, VID 413C, PID 8140, firmware 43.15). I installed the hardware module and BT software stack (Toshiba BT Stack, version v4.41.02(D)). I'm using BT mainly to connect to my mobile phone, for which 'Nokia Suite' v6.85.141 is installed. The Nokia Suite works fine and as expected using the BT link.
*Problem*:
When opening a .doc/.xls file by double clicking it in Windows Explorer, the system response is very slow. Like 40 (!) secs to open a 30 KB Word document. This is reproducible. For some other files, like .pdf the response is much better. Starting Word via the start button and using Word's file/open to access the same file is OK. Opening Windows Explorer using Windows-E hotkey is very slow as well, opening Windows Explorer via start menu is normal.
I do not see any 'heavy' disk access or 100% CPU during the delay.
For the rest, the notebook seems to run OK.
*Findings so far*:
1) Re-installing the Toshiba BT Stack did not improve things
2) When shutting down the PC, frequently the TosOBEX.exe process needs to be ended ‘manually’
3) Uninstalling the BT SW stack makes the PC respond normal again
4) Disabling the BT Manager (system tray, right click BT icon, exit) has same effect
5) Stopping the TosBTmng.exe process removed the problematic effect as well
6) Starting the PC with all non Microsoft processes disabled – except the BT stack – give a normal responsiveness (!)
7) Uninstalling McAfee virus scanning tools does not help
8) Replacing the BT stack with version 5.10.12(T) solves the issue, but creates another problem: process “services.exe” continues to consume too much CPU time (~35…40%)
9) I have not been able (yet) to identity the non BT process(es) which effect(s) this problem
*Questions:*
Anybody familiar with this effect?
Any suggestions for next steps?
Forum’s advice would be appreciated!
Wytze

Hi people. Same thing here.
My Satellite A100 delays opening word and excel 2003 documents only when bluetooth manager is running.
I don't see a cpu load on the services process though (or any other process for that matter).
I had version 4 installed when detected the problem. Switched to 5.10.12(T) and the wait time is still there.
Then I followed the previous post suggestion of wiping-out everything bt related and install again. But still no luck.
Even reinstalled office but that didn't help either.
Some maybe useful information: I'm running Nokia PC Suite 6.85 over bluetooth and Adobe Acrobat Professional 8 which integrates menus in Word and Excel.
Wait time still occurs when killing all PC Suite processes or changing acrobat installation to not integrate in word.
This kind of time wait resembles some king of name resolution timeout. But why only office apps?
Has anyone already have any light to shed on this?

Seeking advice for timer design

Hi,
I am designing a timer application with Flex Builder 3 which
is basically a stop watch that will remember when it was started if
the page is reloaded (on a different computer, for instance). My
original plan was to use JavaScript and mySQL but I'd like to give
it a try with Flex first.
Since Flex doesn't interact directly with databases I'm
wondering if using mySQL to store the timer settings is the best
idea? I think I could manage interfacing it with PHP but I'm not
sure how much trouble this is going to be since I'm a new Flex
user.
How would you approach the project?
Thanks,
tekfetish

Interfacing with a server part is very simple using Flex, PHP
would be just fine - as well as any other server side
language/system.
Here is an Actionscript idea:
You just create a HTTPService variable
quote:
* gateway : this is the communication layer with the server
side php code
private var gateway:HTTPService = new HTTPService();
Then set properties of this service
quote:
gateway.url = '
http://www.myServer.com/myScript.php';
gateway.method = "POST";
gateway.useProxy = false;
If you'd like to pass parameters, use something like this:
quote:
parameters['someNameHere'] ='John Doe';
parameters['whichTimer'] = 'timer 1';
gateway.request = parameters;
Then, define which functions should be called once the
HTTPService returns [resultHandler on success and faultHandler on
error:
quote:
gateway.addEventListener(ResultEvent.RESULT, resultHandler);
gateway.addEventListener(FaultEvent.FAULT, faultHandler);
Then do something in these functions:
quote:
public function resultHandler(e:ResultEvent):void
// your code here...
public function faultHandler(e:FaultEvent):void
var errorMessage:String = "Connection error: " +
e.fault.faultString;
if (e.fault.faultDetail)
errorMessage += "\n\nAdditional detail: " +
e.fault.faultDetail;
Alert.show(errorMessage);
Finally, perform your request:
quote:
gateway.send();

Seeking advice for Wireless LAN solution

I have a site that has a pipeyard in which I am considering covering with Wireless LAN. The transport vehicles that roam the pipeyard have terminals which currently use cellular cards & VPN to connect to an app server that is updated with stock that they move. The server is actually in an office adjacent to the pipeyard. The cellular coverage is poor and the connection drops are frustrating to the operators. For this reason, I am considering covering the area with Wireless LAN and replacing their cellular cards with 802.11a/b/g radios. The pipeyard has no obstructions. The area is outdoors and is about 122 acres in size.
Does anyone have suggestions about what Cisco solution could be applied to this pipeyard so that the mobile operators can maintain continuous connection to their server as they move about the yard?

IPad virgin seeking advice for first purchase

Been a long time Apple snob but haven't broken down to purchasing an iPad until now. My 6 year old MacBook Pro is losing steam quick and I feel like I'm going blind constantly searching the web on my iPhone. Overwhelmed by all the reviews on the various iPads and now the new iPad mini and just really looking for some insider opinions for what might best suit my needs. Love editing pictures and videos, surfing the web and playing music. Don't stream many movies or play with a ton of apps at the moment, but feel like the kids will hijack my device at times so need to consider that for memory. Any thoughts would be greatly appreciated. Thanks!

While there are some photo editing Apps, the iPad is not really suited for deep Photo editing or video editing. Like the iPhone the Apps are nice an friednly, but don;t really offer the control of a desktop Application.
Your better off doing that on a PC.
The iPad Mini would work is you don't have high resolution pics or if you can live with an almost 8 inch screen.
Personally I like the larger screen of the regular iPads as it makes reading things much easier.
The iPad is at its core a media consumption device. You may not think you'll use a lot of memory but it can quickly add up, with photos and videos. Even if you don;t expect to use it. the syaing is its better to have it and not need it, than to not have it and need it.
So personally I'd go for the 32GB as 16GB can become very confining very fast.
