Is it possible to use a tape drive under OS X?

I tried posting this on the OS X discussion page without success, but there have been a number of posts on this discussion page regarding DLT drives so perhaps someone here has the know how?
I have a variety of SCSI drives including LTO, DLT, Exabyte and DAT that I read and write under Solaris and Linux, mainly with the 'tar' and 'dd' commands. I want to do the same under OS X, however OS X does not appear to have the vital tools I am used to such as 'mt' to control the drives. Using a backup program such as Retrospect is not an option since the tapes need to be read on other Unix systems - I have distributed 'tar' written tapes to many other individuals without a problem but never to/from a Mac.
Fingers crossed,
Simon

Hi Simon,
We looked in Unix tools for Mac OS X at one stage, and I was under the impression these guys had a command line tool set which was cross platform compatible.

Never really investigated much further as we decided on a different backup system.
Good Luck

How to use multiple tape drive for single filesystem on single client.

Hello All.
I want to backup single filesystem with multiple tape drive.
Incase of Symantec veritas netbackup "NEW_STREAM" for multi-stream backup.
Backup client has a single backup filesystem like /data1 directory with 4 LTO6 drives.
/data1 directory doesn't have a sub-direcotry, just present a files.
If /data1 directory has a sub-directory like /data1/aaa, /data1/bbb, /data1/ccc , Is it possible to use multiple drives?
Please anybody answer the questions.
Thanks advanced.

When using a personal dropbox account, is it possible to use the mapped drive without downloading all my dropbox files to my hard drive as well?

When using a personal (not business) dropbox account on my mac book pro, is it possible to use the mapped drive only? Currently I have dropbox mapped to my computer but it is also saving a redundant copy of the data on my hard drive. My goal is to pull, edit and save files on the mapped drive only without having a redundant back up of all my dropbox files on my computer wasting valuable storage space. Any advice out there? Thanks in advance for your help!

I don't believe that is accurate, but maybe I am missing something (I am not a Windows user).
Looking at 2 explanation of how to map a Dropbox as a drive…
http://lkeng.org/wp/?p=147
https://www.youtube.com/watch?v=5d8uvseVr5A
Both of those are linking to the 'local copy' of Dropbox. It is not a true 'network' drive as far as I can see (it still requires the local copy on the PC).
Another video suggests using another service to mount the Dropbox, but that is not using Dropbox anymore, it is going through Otixo…
https://www.youtube.com/watch?v=FAIpm2qmglU
Dropbox does not provide easy to use URL's to mount as a network disk so I don't think this is possible on OS X.
Dropbox's forum has this too…
https://www.dropboxforum.com/hc/communities/public/questions/202133795-How-to-ma p-dropbox-as-a-network-drive-on-Mac?loca…
You may need to examine the Windows computers carefully - if they have Dropbox installed & running then all the files are stored on the local machine in addition to the 'mapped drive'.
It looks to me like people are 'redirecting' the local copy to appear like a remote disk just so they can address that path on other machines - each PC is being setup the same. You could create aliases on OS X, but it doesn't help move files off the machine.
Hopefully someone else will contradict me, but I don't think this is how Dropbox works.

Is it possible to use an external drive to play movies on my iPhone 5? I am going on a long flight and only have a 16gb iPhone. I will not have access to wifi, so it would have to connect manually.

Is it possible to use an mSata drive as the primary drive?

Greeting everyone,
I recently bought an HP ENVY Phoenix 810 whiich comes with the MS-7826 (Kaili) motherboard which has an mSata slot with a 16gb msata ssd in it, but it's only being used as a cache. So my question is, is it possible to use the mSata drive as as the main bootable drive along with 3 other hard drives? I'm planning to install a 256 msata ssd along with 3 4tb hd, but want to use the msata as the main one. Is it possible, if so how?
I've come across a few forums where they were having problems with the same thing where they were able to use it as the main drive but as soon as they installed the original bootable drive they system will not boot since the drive didn't have an operating system installed in it and it wont boot from the mSata even though the os was installed onto the mSata. Any ideas?
Thanks in advance.

JCCR510, welcome to the forum.
The mSATA drive in the computer can only be used as cache and not as a boot drive. This is the way that HP has it setup.
You certainly can buy a SATA SSD and install it. As you can see in my signature below, I have Samsung EVO 840 SSD in my 810-135qe. It works great.

Is it possible to use LTO tape library as an Archive Device

Is it possible to use LTO tape library as an Archive Device in Final Cut Server System?
Does it requires any additional hardware/software? Is there any recommendations available?

HI Daro, you might want to look at TolisGRoup's impending BRU "Producers edition" http://www.tolisgroup.com/products/macosx/pe/.
I believe they are looking to have these interfaces to some of the  pro-apps. [Will stand corrected].
Whatever the archiver.app, it needs to know where the objects start and end on the data tape volume (e.g Ultrium LTO4]. THis is simply done by knowing the BLOCKID ofthe first block of the file(s) that have been archivied on the tape (this was retrieved when the ARCHVE operation was done via RED BLKID cmd). This is simplest form. That way the software can "+LOCATE BLOCK scsi tape cmd+" to that spot on that tape volume using HIGH SPEED SEARCH and read in what it needs.
Some rather spiffy .apps like SGL's FLASHNET for OSX and others (DIVARCHIVE on windows) will resolve a TCR to a location DATA TAPE volume based on the known codec or in SGL's case, the interface through it's MXF archive implementation. This could be very hand for large high bitrate objects. .
I am waiting for this myself. It is currently in BETA.
Contact Tolisgroup and see what the status is of BR PE. http://www.tolisgroup.com/products/macosx/pe/

How to use multiple tape drive from single client when I want to backup single filesystem?

Hello All.
I want to backup 1 filesystem using 4 tape drives for reducing backup time.
In case of symantec veritas netbackup, they can user "NEW_STREAM" for multi-streaming backup.
Please anybody let me know that how to do use multiple tape drive for single client.
1. Backup Source server : Linux (1 client)
2. Backup Soucre : /data1 (500GB)
-> Current directory structure doesn't have sub directory under /data1, just files present under /data1
If direcotry struceture has a sub-direcotry like( /data1/aaa, /data1/bbb ), Is it availble to use multiple tape drives?
3. Tape Drive with OSB : LTO6 * 4 drives
Thank you.

You would have to create a different dataset for each sub-folder. If you only have files at the top level folder then even the NEW_STREAM option couldn't be used to split the job.
Organise it into folders and then create datasets in a client folder such as :
/usr/local/oracle/backup/admin/config/dataset/Linux/data1_aaa
/usr/local/oracle/backup/admin/config/dataset/Linux/data1_bbb
Then in the schedule you just specify the Linux folder. In each dataset you list the hostname and the folder name, such as :
include host Linux
include path /data1/aaa
Now it will create a new job for each dataset and therefore each folder.
Thanks

Is it possible to use multiple hard drives with iphoto?

I am pretty new to Mac's so bear with me, I used to use multiple hard drives on my pc with my photos seperated by catagory in different hard drives. Is it possible to run iphoto with multiple hard drives without the photos loading onto my Imac? If so, How do I set it up. I have tried importing to a external drive, but when I check the file path of the photos it shows my Imac hd in the address. I seriously dont know why I cant just add the external hard drive as a library and have Iphoto work, Help

There are instructions - and not the caveats - on how to do what you want below.
However, you'e not quite grasping iPhoto:
I used to use multiple hard drives on my pc with my photos seperated by catagory in different hard drives.
When you do this, you're using the Finder (or file manager) to categorise the photos. All well and good, but why? That's exactly iPhoto's job. iPhoto is a database designed to help you manage your pics - including categorising them.
Anyway:
*How to do it:*
Simply go to iPhoto Menu -> Preferences -> Advanced and uncheck 'Copy Files to the iPhoto Library on Import'.
*What Happens:*
Now iPhoto will not copy the files, but rather simply reference them on your HD. To do this it will create an alias in the Originals Folder that points to your file. It will still create a thumbnail and, if you modify the pics, a Modified version within the iPhoto Library Folder.
*Some things to consider:*
1. Importing and deleting pics are more complex procedures. You have to to put the files where they will be stored before importing them. When you delete them you'll need to remove the files from the HD yourself.
2. You cannot move or rename the files on your system or iPhoto will lose track of them on systems prior to 10.5 and iPhoto 08. Even with the later versions issues can still arise if you move the referenced files to new volumes or between volumes.
3. Most importantly, migrating to a new disk or computer can be much more complex.
4. *Because iPhoto has no tools for managing Referenced Files, if, for some reason, the path to the photos changes then you could find yourself resolving aliases for +each photo in the Library+ one by one.*
My own opinion:
I've yet to see a good reason to run iPhoto in referenced mode unless you're using two photo organisers
If disk space is an issue, you can run an entire iPhoto Library from an external disk:
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.
If you're concerned about accessing the files, There are many, many ways to access your files in iPhoto:
*For Users of 10.5 and later*
You can use any Open / Attach / Browse dialogue. On the left there's a Media heading, your pics can be accessed there. Command-Click for selecting multiple pics.
Uploaded with plasq's Skitch!
You can access the Library from the New Message Window in Mail:
Uploaded with plasq's Skitch!
*For users of 10.4 and later* ...
Many internet sites such as Flickr and SmugMug have plug-ins for accessing the iPhoto Library. If the site you want to use doesn’t then some, one or any of these will also work:
To upload to a site that does not have an iPhoto Export Plug-in the recommended way is to Select the Pic in the iPhoto Window and go File -> Export and export the pic to the desktop, then upload from there. After the upload you can trash the pic on the desktop. It's only a copy and your original is safe in iPhoto.
This is also true for emailing with Web-based services. However, if you're using Gmail you can use iPhoto2GMail
If you use Apple's Mail, Entourage, AOL or Eudora you can email from within iPhoto.
If you use a Cocoa-based Browser such as Safari, you can drag the pics from the iPhoto Window to the Attach window in the browser.
*If you want to access the files with iPhoto not running*:
For users of 10.6 and later:
You can download a free Services component from MacOSXAutomation which will give you access to the iPhoto Library from your Services Menu. Using the Services Preference Pane you can even create a keyboard shortcut for it.
For Users of 10.4 and later:
Create a Media Browser using Automator (takes about 10 seconds) or use this free utility Karelia iMedia Browser
Other options include:
1. *Drag and Drop*: Drag a photo from the iPhoto Window to the desktop, there iPhoto will make a full-sized copy of the pic.
2. *File -> Export*: Select the files in the iPhoto Window and go File -> Export. The dialogue will give you various options, including altering the format, naming the files and changing the size. Again, producing a copy.
3. *Show File*: Right- (or Control-) Click on a pic and in the resulting dialogue choose 'Show File'. A Finder window will pop open with the file already selected.
If you really want to spread your photos across volumes like this, Aperture would be a better fit.

Is it possible to use 2 firewire drives as TM backup with raid?

It seems that RAID is used for a lot of things, but I haven't been able to figure out if this is a proper use.
I have two hard drives. (1 TB/320 GB) I'd like to format the two drives into one using RAID in Disk Utility and use fore Time Machine backups. Is this possible or advisable? If this would work, is there a limit to the number of drives in a RAID setup?
Thanks.

It's certainly possible to use a proper RAID with Time Machine, but you don't have the drives to create a proper RAID. A proper RAID system should be built using identical drives - same capacity, same brand and ideally, even the same firmware.

Sony SDT-9000 scsi tape drive under udev

I've installed Arch .7 and have updated the system with pacman. I set up the system to use udev.
I have an Adaptec AHA-7850 scsi card with a Sony SDT-9000 tape drive attached as the only scsi device.
When I check out /dev, there is an sg0 device, but no tape, st0, nst0, etc. dmesg shows the tape drive identified at boot, and cat /proc/scsi/scsi also shows it.
I can't use mt on the sg0 device, and I'm not sure if that is my controller or my tape drive, and if the tape drive, how I gain access to it.
Thanks in advance.

Ok, I figured it out. I was using kernel26-scsi, but didn't realize I still needed to load the scsi tape module (st) into rc.conf. Did that, now it works.

Hello Kulvinderbuttar,
I understand that you are not able to make the recovery media.
Are you using recovery media creation?
Here is a link to walk you through the steps to create the recovery media.
The flash drive that you are using needs to be empty and may need to be reformatted before you can make the recovery media.
Let me know how everything goes.

Possible to use DVD-RW drive from Asus laptop as external drive for S10?

I just purchased a Lenovo S10 netbook, which of course does not have a built in DVDRW. I have an older Asus laptop with a removeable DVD-RW drive. Is it possible to get some sort of case to turn it into a USB external drive?

the links that BaileyMoto posted will work for most laptop dvd/cd drives. i've got one, and it works great with an nec drive in it. only takes one cable for power and data, so you don't use up both ports on your computer.
only the newer laptop cd/dvd drives are sata. your old drive from your asus should work fine in that enclosure. the first link is for the board that comes in the enclosure that's in the second link.

Is it possible to use Target Display Mode under Bootcamp on iMac 27?

I run Solidworks under Windows XP in Parallels 5 on my pre Unibody MBP since a couple of years. Works well but I could need more speed and screen size.
I'm thinking that the following setup would suit me well if it works:
iMac 27 running Windows in Bootcamp
New MBP running OSX
Is it possible to connect the MBP to the iMac and use Target Display Mode when the iMac runs Bootcamp? Haven't been able to find a good answer.
If not - Apple: Will you please implement this in a Bootcamp update...?

Welcome to the Apple Discussions!
If I understand your question, you wish to access the MBP in TDM from the iMac booted into Windows. The iMac using Windows should see the MBP in TDM as it would any other connected external USB or FireWire HDDs. However, you should also face the limits that the version of Windows you use may have regarding reading disks formatted for Macs.

We use a IBM TotalStorage 3573 Tape Library. 1 Drive with 23 slots.
It is a Dell TL2000 tape drive.
The DPM-Server is a x64 Windows 2012 R2 with Microsoft System Center Data
Protection Manager 2012 R2 Version 4.2.1235.0
In Device Manager I have a Medium Changer device which is IBM TotalStorage 3573 Tape Library(Driver Version 6.2.4.1)
and Tape drives has IBM ULTRIUM 6 HH 3580 TAPE DRIVE(Driver Version 6.2.4.1)
The tapes are not write protected.
Is this a tape issue or a protection-agent failure? Any suggestions??

Hi,
We have seen this when using OEM drivers - please install the Microsoft in-box tape drivers.
1) Open device manager
2) Locate the tape drive
3) Right-click and look at the properties.
3) Under the DRIVER tab, select UPDATE DRIVER
a) Select the Install from list or specific location (Advanvced) - next.
b) Select Don't search. I will choose the driver to install. - next.
c) Uncheck the Show comtabile hardware checkbox.
d) Highlight LTO under the manufacturer.
e) Highlight the LTO tape drive under model - then next.
f) This should install the Microsoft ltotape.sys driver.
4) Rescan the tape library in the DPM console, if a duplicate tape drive appears, then run the following utility.
c:\program files\Microsoft dpm\dpm\bin\DPMDriveMappingTool.exe to remap the tape drive and remove the duplicate
5) Now inventory the library and try a new backup.
