A question about partial backups.

In the usual way I backup my iMac to an external hard drive using 3rd party software and that's fine. But for additional security I bought two additional solid state drives of about 60 GB so I could make extra copies of some important files that change frequently.
My question is, what's the best way to backup these smaller SSDs? I can plug each into the main external drive and the iMac but not into each other -- can't daisy-chain them. Is there software made just for this?

There is no software for daisy chaining two drives that cannot be daisy chained. You can use your backup utility or some other utility to backup the files you want individually to the SSD.

    iTunes is required to transfer iTunes content from your iTunes library on your computer - music, movies, TV shows, podcasts, 3rd party apps, and selected photos from your computer to your iPhone. iTunes also serves as the sync conduit for contacts and calendar events between your iPhone and the supported address book and calendar application on your computer.
    iTunes creates and maintains a backup for your iPhone which is updated by iTunes as the first step during the iTunes sync process. The backup does not include all data on your iPhone. The backup does not include any iTunes content - music, movies, TV shows, podcasts, or 3rd party apps. All iTunes content on your iPhone should remain in your iTunes library on your computer and the backup doesn't include any photos transferred from your computer. All photos transferred from your computer should remain on your computer as well.
    This link provides the data that is included with your iPhone's backup.

  • Thunderbolt / USB3 questions about external backup drives for my new MacBook Pro

    I have a new MacBook Pro retina 13". It has two USB3 and two Thunderbolt2 ports.
    Until now on my iMac I've kept two backups on two WD USB2 drives. I have never had any problems with any of my WD Passport drives. One for Time Machine and one for CCC (a complete bootable clone incrementally created at 3:30 am every day).
    I'd like to get new portable drives for my MBP for these backups going forward and have a few very basic questions, since this is the first time to have a device with a USB3 port, and the first time I even heard about Thunderbolt.
    If I get a USB3 drive and need to use it to restore things on my older iMac, which just has USB2, will it generally connect and run with USB2 at a slower speed? Or would I have to get a drive with both USB2 and USB3 ports?
    Is Thunderbolt just an Apple thing? Or is it a new standard widely used by peripherals now? I just never heard of it before. Is it faster than USB3?
    Is it common for drives to have both Thunderbolt and USB2 connections?
    Are there "hubs" for Thunderbolt like there are for USB? Considering the limited number of ports, I'm wondering the best way to connect 2 external drives. My iMac has 4 USB2 ports on the back, and I connect one drive separate to each of those ports, rather than going through a hub.
    Is USB3 like USB2 in that if you have even 1 USB2 device (e.g. my Logitech headset) connected to a USB3 hub it will slow down everything on that hub to USB2?
    Any recommendations for good, portable backup drives?
    Thanks,
    Doug

    Hi Doug,
    Lets see if we can address some of these:
    If I get a USB3 drive and need to use it to restore things on my older iMac, which just has USB2, will it generally connect and run with USB2 at a slower speed? Or would I have to get a drive with both USB2 and USB3 ports?
    USB3 is "backwards compatible" with USB2 so plugging a USB3 drive into a USB2 port should work, but at USB2 speeds.
    Is it common for drives to have both Thunderbolt and USB2 connections?
    Drives sold as Thunderbolt often (not always) have USB as well, drives sold as USB never (in my experience) have Thunderbolt connections.
    Are there "hubs" for Thunderbolt like there are for USB? Considering the limited number of ports, I'm wondering the best way to connect 2 external drives. My iMac has 4 USB2 ports on the back, and I connect one drive separate to each of those ports, rather than going through a hub.
    Yes there are (but don't expect them to be comparable in price to a USB hub) e.g. see here: http://www.belkin.com/uk/p/P-F4U055/
    Is Thunderbolt just an Apple thing? Or is it a new standard widely used by peripherals now? I just never heard of it before. Is it faster than USB3?
    I'ts an Apple technology (like firewire) and is far from widely used on peripherals.  There ARE Thunderbolt drives etc by companies such as LaCie, WD etc but they are still very expensive (3 or 4x the price of an equivalent sized USB drive).  For some this was a worthwhile expense since Thunderbolt is many times faster than USB2.  But the arrival of USB3 has, in my opinion, changed the landscape.  Yes, Thunderbolt is theoretically faster than USB3 (up to twice as fast) but benchmark tests have shown that in real world situations, the speed difference varies from no difference to Thunderbolt being 25 or 30% faster.  When you take into account that USB3 drives are more common than Thunderbolt and are only a little more expensive than USB2 drives at present, then it's a "no brainer" as far as I am concerned.
    Hope this helps.

  • Simple question about iPhone backups and password

    I can't remember the password to my iPhone-backup in iTunes. But, phew, I haven't lost any data, as I have my iPhone with all data intact. So I deleted the backup in iTunes, and tried to start a fresh backup with a new password. But alas, that doesn't seem to be possible (it backs up, but doesn't ask for a password, and when trying to uncheck encryption I get asked for a password).
    Does this mean iTunes now won't let me back up and retrieve the data I actually have on my very own phone? And does it mean that I now have two options:
    a. Keep on using my iPhone, keeping the data on it, but without the ability to backup and retrieve the backups, or
    b. restore and set up my iPhone as a new device, losing all my data

    If you update you will not be able to go back to a previous iOS version. The iOS is not included in the backup.  The following link gives details of what is included: iTunes: About iOS backups

    I have backed up my old iPhone that used Ios 6. Now I have a new iPhone and my question is: Can i restore that new one if it has ios 7? Will it change back to Ios 6 or not??? Thanks!!!

    Yes, you can restore the new iPhone from the old one. It will not restore the older version of iOS; that's not part of the backup. To see what is in the backup, go here;

  • Question about image backup and restore

    W701 about 18 months old.
    I regularly back up using Rescue and Recovery. It says: "Saving an image of your system to your USB external storage device." I haven't found a way to get any clue about what is included in the image. I can't select properties of the backup, or find out what the size is.
    I've also tried google, and of the new info, none of it was useful.
    Does this backup include both drives, C and D?
    And it seems that this backup is just to do a restore on the same computer. If I even replace the SSD with a larger rotating hard drive, I don't suppose I'd be able to use the restore, would I?

  • Question about full backup and Transaction Log file

    I had a query will taking full backup daily won't allow my log file to grow as after taking the full backup I still see the some of the VLF in status 2. It went away when I manually took the backup of log file. I am bit confused shall I
    perform backup of transaction log and full database backup daily to avoid such things in future also until I run shrinkfile the storage space from server won't get reduced right.

    yes, full backup does not clear log file only log backup does. once the log backup is taken, it will set the inactive vlfs in the log file to 0.
    you should perform log backup as the per your business SLA in data loss.
    Go ahead and ask this to yourself:  
    If  a disaster strikes and your database server is lost and your only option is restore it from backup, 
    how much data loss can your business handle??
    the answer to this question is how frequently your log backup should be?
    if the answer is 10 mins, you should have log backups every 10 mins atleast.
    if the answer is 30 mins, you should have log backups every 30 mins atleast.
    if the answer is 90 mins, you should have log backups every 90 mins atleast.
    so, when you restore, you will restore latest fullbackup+differential(latest one taken after restored fullback)
     and all the logbackups taken since the latest(restored full or differential backup).
    there several resources on web,inculding youtube videos, that explain these concepts clearly.i advice you to look at them.
    to release the file space to OS, you should the shrink the file. log file shrink happens from the end upto the point it reaches an active vlf.
    if there are no inactive vlf's in the end,despite how many inactive vlf's the log file has in the begining, the log file is not shrinkable
    Hope it Helps!!

  • Basic questions about config backup/restore

    I've searched around with limited success. I've just inherited the Ironport devices in our enviornment and need to perform an OS upgrade of our cluster. Prior to doing so, I want to backup each members config file. (also, I want to do this before doing any config changes)
    If I back up each member's config to the device, how I can access/edit these config files so I can replaced the masked password fields with the actual passwords?
    I'm aware of the unmasked/hashed password version of the file, but we'd like to avoid that if we can.

    The config file itself is just a text/xml file and most good text editors (vi/textpad) will handle it easily.
    Even when passwords are not masked, they are always encrypted. The only way to manually insert a password would be to encrypt it and put the result back in the config file.
    As long as you are choosing strong passwords (hint) it is not at all an easy task to force decrypt the hashed password string. Even if you are completely paranoid, just store the config file somewhere in an encrypted format.
    Bottom line: don't mess up your "backup" by manipulating it in a way that could render it useless just when you most need it. Manual editing of config files is tricky and AFAIK not officially supported in any way.

  • Is there anybody out there that can answer the question about the backup on the external hard drive?

    I need some help please. I have been using an external hard drive to keep my itunes on because the file was so big. I understand that Itunes backs up all of the text, photos, contacts, ect.. everytime you sync your phone. Is this where itunes is storing all this information and if so how do I find it?

    Hi,
    I agree that the back up file is big and the file you saved was your iTunes Library (%USERPROFILE%\Music\iTunes) but, your iTunes saves your backup data in a different location.
    if you are on Windows XP: %USERPROFILE%\Application Data\Roaming\Apple Computer\MobileSync\Backup
    if you are on Windows Vista/7: %USERPROFILE%\AppData\Roaming\Apple Computer\MobileSync\Backup
    so i suggest you also back up those folder(s) in your computer to your external hard drive.(I recommend that you backup the iTunes & MobileSync folder found in AppData as you may need if in the future.)
    as for the iTunes Folder found in Music/My Music folder, that is your iTunes library and you should also backup that folder so that in the future, if anything happens to your computer, you will be able to still sync you iDevice on another computer with the same library.
    Note: In the Backup Folder, there will be a folder with a very long name. If you have several iDevices backed up, you will find it useful to know that each iDevice has a Identifier (UDID) and that the long name of the folder is your iDevice Indentifier (UDID) and the "-" next to the UDID is the Date followed by the time.
    eg.2b6f0cc904d137be2e1730235f5664094b831186-20101016-222905
    Meaning UDID was 2b6f0cc904d137be2e1730235f5664094b831186
    the Date was 16/10/2010 (20101016)
    and the Time was 22 Hours 29 Minutes 5 seconds (222905)
    to Find your iDevice UDID, refer to this page: http://support.apple.com/kb/HT4061
    Hope this helps.

  • Question about partial access with "infinite" partial length

    Suppose you want to read partial data starting at offset 100 but you don't know the total length.
    Or, suppose you want to write partial data, replacing all bytes from offset 200 to the end of the data.
    One would think that calling DatabaseEntry.setPartialLength(Integer.MAX_VALUE) would do the trick... but I'm worried that this will cause integer overflow in the internals of the JE library and screw things up.
    Is using DatabaseEntry.setPartialLength(Integer.MAX_VALUE) safe?

    Hi,
    Looks like this is answered by the javadoc for DatabaseEntry.setPartial. Please take a look and let us know if there is some way we can improve the doc.

    but than I've got next question, something like "do you want to merge data or you want to overwrite your phone" and I've pressed "merge" by accident
    Now....is there any way back from it? How I can get data from all apps back to my phone ?
    All app's are there, but all of them are empty ! Please help!

  • Partial backup question

    Hallo developers.
    We are testing the partial backup procedure and we have some doubts.
    We would like to know how the partial backup is made consistent; if during the operation of backup (the copy of the jdb files) the application writes to the last jdb file after a commit is there any problem of consistency?
    In the guide is written clearly that you can copy the files during database operations: when you open the environment from the backup is the new environment reconstructed from the last chekpoint?
    Kind regards
    Massimo

    Hi Massimo,
    We would like to know how the partial backup is made
    consistent; if during the operation of backup (the
    copy of the jdb files) the application writes to the
    last jdb file after a commit is there any problem of
    consistency?JE uses a log based storage system. Once a record is written to the log, it is never overwritten again -- inserts, updates, and deletes are only ever appended to the log. In addition, there are never any "holes" in the log file. Therefore, if you copy log files from the environment directory in lexicographic order (essentially numerical hex order), and you copy the sectors in those files in ascending order, you will always have a consistent backup.
    For example, if you have files 000000ab.jdb through 000000af.jdb and you copy them in order (ab, ac, ad, ae, af) you will have a consistent backup snapshot of your environment. If you want to do an incrental backup on top of that backup, then you should copy any files that have been modified since the last backup was started. In this example, if 000000af had been modified (as it probably would have been since it was the last file, but probably not completely full when the backup finished), you would copy that file and any ones after that (e.g. b0, b1, ...). When you restore, you would take the most recent (and most full) copy of af (as well as all the other files).
    When the recovered databases are opened, JE runs a recovery (as usual) and makes the transactional state consistent. So if your backup included records from a transaction had not yet committed, and the backup did not copy the commit record, that transaction would be rolled back at recovery time.
    Now what causes a problem is if the cleaner is running. I won't go into a lengthy discussion of it here, but you can read about it at
    http://www.oracle.com/technology/documentation/berkeley-db/je/index.html
    under the javadoc for com.sleepycat.je.util.DbBackup.
    The net result is that you should use the DbBackup utility class for your backups.
    In the guide is written clearly that you can copy the
    files during database operations: when you open the
    environment from the backup is the new environment
    reconstructed from the last chekpoint? Correct. Because the log file is append only, when you copy files you will see a consistent, although possibly not most-recent, state of the database. By the way, a checkpoint is really just a performance improvement -- it is possible that there are no checkpoints in the database to recover from, but JE will still be able to recover the Environment.
    I hope this is useful.

  • A question about restoring from cold backup(control file backup not clear)

    Hi,
    I had another question about restoring the cold backup. My database is in noarchivelog mode and after taking a consistent cold backup, all I need to do is to restore the backup right? -Why I got this question is because: when I backup my control file to trace, I see statements like this:-----
    -- Commands to re-create incarnation table
    -- Below log names MUST be changed to existing filenames on
    -- disk. Any one log file from each branch can be used to
    -- re-create incarnation records.
    -- ALTER DATABASE REGISTER LOGFILE '/uo1/app1/arch1_1_647102958.dbf';
    -- Recovery is required if any of the datafiles are restored backups,
    -- or if the last shutdown was not normal or immediate.
    RECOVER DATABASE
    -- Database can now be opened normally.
    ALTER DATABASE OPEN;
    My database is in noarchivelog mode now so don't know why these statements (of register the logfile) is there in the backup of control file? so when I restore the cold backup of this database, it will still work correct? (there is no logfile I have only CRD files in cold backup -no archive log files.)
    thanks
    Nirav

    Thanks for your inputs! It is most useful to me.

  • A question about backup

    hello chris:
    I have a question about backup, last time I had done a incremental backup, after a long time, i found the system record the log LSN, and the log can't remove.
    Command> CALL ttLogHolds();
    < 306, 12446304, Backup , /timesten/TimesTen/backup/data >
    < 1082, 7749304, Checkpoint , data.ds0 >
    < 1082, 21337776, Checkpoint , data.ds1 >
    < 1082, 22546632, Replication , DATA >
    how to resolve this problem?? Can TimesTen not record the backup lsn??
    thank you

    Hi,
    In TimesTen, incremental backup is driven off the transaction log files, just like replication and XLA, So, once you have initialised an incremental backup set, logs must be retained until they have been copied away to the incremental backup set. So, to ensure that logs can be purged you need to run an incremental backup frequently, either manually or by scheduling using something like cron. If you do not run an incremental backup then logs will be 'held' and cannot be purged by checkpointing (which is what you are seeing).
    If you no longer require the incremental backup set then you can disable the incremental backup tracking using ttBackup -type incrementalStop and then logs can be purged normally.
    Chris
