Can I use cp or dd to perform hot backup?

Hi,
I am wondering whether we can use 'cp' or 'dd' to do hot backup for bdb. IS it safe enough?
If so, why bdb still need to supply the utility tool db_hotbackup?
Thanks.

The behavior/implementation of 'cp' is different from system to system. In Solaris in particular it doesn't work as you might expect. db_hotbackup was written to give you a supported, reliable way to do a hot (live) backup of the database. You don't have to ship the utility, you're free to copy the code from the utility into your application itself. Would that work?

  • Can I use Time Capsule only as a WiFi backup disk w/out having to configure it as my main router?

    I already have an Airport Extreme that works great. Can I use Time Capsule ONLY as a WiFi backup disk w/out having to configure it as my main router with my Internet modem?

    Can I use Time Capsule ONLY as a WiFi backup disk w/out having to configure it as my main router with my Internet modem?
    Yes, you have two options here, each with advantages and disadvantages.
    Option 1...connect the Time Capsule to your AirPort Extreme using an Ethernet cable connection. Turn off the wireless on the Time Capsule since your AirPort Extreme is already providing wireless.
    Advantages...easy to configure, you can backup either over wireless or plug directly into one of the Ethernet ports to backup large files 3-5 times faster than wireless.
    Disadvantages...none, except it requires a wired Ethernet connection to the AirPort Extreme.
    Option 2....configure the Time Capsule as a wireless only hard drive.
    Advantage.....you can locate the Time Capsule anywhere you want as long as it can receive a good wireless signal from the AirPort Extreme.
    Disadvantages....harder to configure, backups will occur only over wireless.

  • Can you use airport extreme 802.11n for files backup

    Can you use airport extreme 802.11 for files back up and sharing

    You can if you connect a hard drive that has been formatted correctly to the USB port on the AirPort Extreme.
    Apple does not officially support Time Machine backups for this type of setup, but you could store regular files this way.

  • Can on use more than one hard drive to backup with time machine ?

    Can one use more than one hard drivewith time machine ?

    Yes, if you have the Mountain Lion operating system installed on the Macs that you want to back up.
    I don't know what the maximum number of hard drives might be, but I have tested with 4 and it works fine. Time Machine automatically rotates the backups when you do this, so drive #1 will be backed up first, then #2, #3, etc. and then back to #1, etc.

  • Can I use my Pismo's external Firewire as backup for my iBook?

    Hi,
    How can I use my Pismo's Seagate 300Gig external Firewire HD to back up my iBook without destroying all of my Pismo data? My Pismo's internal HD is only 10Gig and my iBook's internal HD is 20Gig.
    My external has 2 partitions (10 Gigs of which are a cloned mirror of my Pismo's 10Gig HD and the rest are allocated for disc images of all my lectures). Can it be done without destroying all the data backed up and stored/filed on the external?
    A Little Fish in the BigMac Pond

    Little Fish,
    Just out of curiosity, one of my three partitions on my HD has OS 9.2.2 plus applications, etc. I started up Carbon Copy Cloner on my 10.4.7 partition and cloned my 10.4.7 over to the 9.2.2 partition. None of the existing files was disturbed on the 9.2.2 partition plus the root level (that's what you see when clicking open the HD icon) of the partition was organized just as if both 9.x and 10.x had always been there.
    However, this was a one-time CCC. If you are concerned about not disturbing the disk images already on the large partition and you still want to backup the iBook, you might instead use CCC's option to Create a Disk Image on Target. To restore, you would boot to the other partition, mount the disk image file and restore to the target. I have NOT tried this approach so I have no comment on it.
    I would say this...if your stored image files are very important, you must take all precautions and avoid risking the integrity of that partition. I would thus not be copying over a working OSX; a disk image is probably safer but if that partition with your disk images is corrupted, do you have another backup? I may be overly cautious but I just want to make sure you know the potential pitfalls.

  • Can I use my computer during a My Password backup?

    My first backup using My Password is going to take hours. Can I use my computer during the backup?

    Yes. But expect it to be sluggish at times, especially when trying to read from or write to another disk.

  • Perform hot backup on to a tape

    Can I get a step by step procedure to perform a hot backup of 500 gig db on to a tape. We do not have catalog database and database version is 10.2.0.1.
    Thanks

    You are asking to abstract a manual. This means you can expect nasty replies because no one wants to do voluntarily what you apparently avoid to do: read documentation.
    RMAN can not backup directly to a tape, it needs a media management library, like Legato, or Tivoli, or Netbackup or ....
    Yes you need to allocate channels, and the exact method is different for each library product, so no info is possible.
    Backup database also back ups the controlfile. In Oracle 10g and higher you should have autobackup of the controlfile to disk enabled, this replaces and supplements the catalog database.

  • Can I use the Time Capsule strictly for system backup and continue to use my Airport Extreme for all my wireless needs

    I want to use the Apple Time Capsule as an external drive and continue to use my Airport Extreme for all my wireless needs. Can I do that? The reason I ask is that my Time Machine utility cannot find the TIme Capsule - it only shows me the Airport Extreme, even when I "Rescan". SO I am unable to use the Time Capsule.

    You will need to connect an Ethernet cable from one of the LAN <-> ports on the AirPort Extreme to the WAN "O" port on the Time Capsule.
    Perform a "hard reset" on the Time Capsule by holding in the reset button for 9-10 seconds, then give it another minute to restart to a slow, blinking amber light.
    Open AirPort Utility, select the Time Capsule, and click Manual Setup
    Click the Time Capsule tab located below the row of icons to assign a name to the Time Capsule, a device password, and adjust Time Zone settings.
    Next, click the Wireless tab located to the right of the Time Capsule tab
    Change the setting for Wireless Mode to Off
    Click the Internet icon, then click the Internet Connection tab
    Connect Using = Ethernet
    Connection Sharing = Off (Bridge Mode)
    Click Update at the lower right to save the settings and allow 30 seconds for the Time Capsule to restart to a green light.
    You are all set

  • Can we use SSD in D13 VMs as a backup location

    Team,
    Any comment, as it is taking us 4-5 hours to take 80GB backup on storage space  on D13 VM. While looking to reduce this time, thought of using SSD as a backup location(underlying assumption that it has faster read/write speed although it is not recommended
    for keeping critical data).
    Any further suggestion on taking reducing the backup/restore time other than the compression feature
    Regards
    Gaurav

    Hi,
    Thanks for your post.
    The SSD drive (D:\) is not persistent, so its contents and permissions will be lost if the VM moves to a different host. This can happen in case of a host failure or a VM resize operation.
    Do not store your data or log files there. Use (persistent) drives from Azure Storage.
    If using TempDB and/or Buffer Pool Extensions, SQL Server requires accessing the directory specified to store them. The following section describes how to store SQL Server TempDB and/or Buffer Pool Extensions on the SSD drive and automatically recreate
    directory if the VM moves to a different host.
    You could refer to this article for more detail information:

  • Can i use another mac as a time machine backup?

    HI,
    I was just wondering if i can connect two macs via ethernet or firewire and use of of them to do a time machine backup of the other mac.

    The two machines are connected by Ethernet via an 100BaseT hub and are on a local network. The server has a static IP address and my primary machine uses DHCP. I don't know if this would work for IP over FireWire.
    Truthfully if I were you I would just go ahead and spring for a good FireWire 800 hard drive (and cable of course) to use for your back-ups. I have the server because I use it for a lot of other things - it is available for Time Machine backups for our whole group of computers and I serve a small web site from it for internal use.

  • Can i use and old ipod for time machine backups?

    i've reformatted the ipod and enabled it for use as a hard drive. will it work with time machine? time machine doesn't seem to be recognizing it...

    Generally I wouldn't rely on the iPod for backing up because of how power and caching is taken care of on the iPod. Small files is one thing. But the spin up and down of the iPod can make backups unreliable if done of a system as a whole.

  • Can't use time capsule because it won't backup a "case sensitive drive".  what does this mean?

    Back up fails because the time machine can't back up a "case sensitive" disk.  I have no idea what this means or how to fix it.

    What are you backing-up to, an external HD or a Time Capsule?
    Check the Format of your internal HD and your external HD (assuming that's what you're backing-up to), via Disk Utility (in your Applications/Utiliites folder).
    Click the partition (indented under the main line for the drive) in the sidebar, and see what's shown at the bottom:
    Do the same for your Time Machine drive, and report what you find.

  • How can I use the 4G monthly plan as a backup for WiFi access

    I plan to get an Ipad that I will mostly use with wifi but it would be nice to switch to 4G on rare occasions when wifi is not available.  If I sign up for the monthly 4G prepaid do I have to pay for months when I don't use it?  The contract language in Verizon's brochures seems to suggest I do but I a rep in one of their stores said the opposite.

        We appreciate your interest in utilizing 4G prepaid data for your device WISE1049-5319! Please contact prepay support activations at 877-777-5759. I'm sorry we only support postpaid service here.
