    mfs backup/restore

    I have 3 hr10-250s... all with single 250gb drives
    just started tivoin late this summer btw thank you all !!
    linux nub
    had them all hacked under 3.1.5f, even got the mfs_ftp working w/ insertion

    now the 6.3b is out
    I want to migrate them all to 6.3b HME/HMO !!

    Currently
    one is at 6.3b
    another at 3.1.5f with the 6.3b slices
    third is at 3.1.5f with only 6.3 slices (recently redone with older instantcake)

    none have recordings I need to preserve, those have been moved to my pc as tmf's

    seems the slices for 6.3b are now out of the stream.

    what I am attempting to do is mfsbackup the drive that has the 6.3b slices and then restore it to the drive with only the 6.3 slices.

    I do not want to update my box with the slices for 6.3b, until I get them over to the 3rd box.

    I have followed hindesdale's guide and my 3rd tivo that has the restore image just continues to reboot.

    mfsbackup -f 9999 -6so /mnt/dos/tivo.bak /dev/hdc

    goes fine and my file is just under 200mb, then I swap out drives and

    mfsrestore -s 127 -bzpi /mnt/dos/tivo.bak /dev/hdc

    I do not see any errors and it cleans up and is complete.

    Any help or guidance greatly appreciated

    I have omited the -s 127 now, I see I should not have used it since my drives are the same size ( 250gb )

    I tried this

    mfsrestore -bzpi /mnt/dos/tivo.bak /dev/hdc

    and all seemed to go well once again.

    Results are the same, constantly reboots before I ever get totally booted

    This might be part of the problem:
    Code:
    -f 9999
    With the HR10-250 I'm not sure that all of the relevant system pieces have file-id's below 9999. You might be missing some key bits.

    Thanks for the reply Narf

    Last night was spent doing a

    dd copy of my 250gb hd that has the 6.3b slices on it

    today I am back doing mfsbackup so I do not have to go through a dd again

    when I ran
    mfsbackup -f9999 -6so /mnt/dos/tivo.bak /dev/hdc
    I got an Uncompressed File Size of 790 mb

    today I ran this
    mfsbackup -l32 -6so /mnt/dos/tivob.bak /dev/hdc
    I get an Uncompressed File Size of 1194 mb

    Not sure how to check to see if it works without jepardizing my freshly dd'd drive, I do have smaller drives 80gb laying around.

    You can reduce the size of your backup by correctly choosing the -l or -f parameter. If you remove essential objects you wind up with an image that will not produce a working drive. You cannot produce an image that will restore to a smaller drive (unless you start with a drive that had been previously expanded).

    The ever-helpful Jamie has instructions in this thread for determining the optimal settings to create a minimal backup. I understand about not wanting to waste the hours spent copying the original drive. Might I suggest asking Santa (or your closest Santa-substitute) for a 400 Gig drive for Christmas?

    I know on my hr10-250, the the -f9999 does not give you a working backup.

    Maybe at one point in time it did, the -l is the way to go for anyone with a hr10-250

    I can verify it does give a working copy

    It probably won't work without adding a space between the -f and 9999.
    Please don't PM me or any other members looking for personal assistance. You'll do better by posting (after you've exhausted the search feature, of course) and taking advantage of the collective expertise of the membership instead of a single individual that may or may not be able to help you. Thank you and enjoy your stay at DDB!

    so true, did a backup the other day with -f 9999 and it worked perfectly. Spaces or lack there of will kill you.....

    humm..

    as you can see from below, I used the space, was even quoted as using the space, I just made a typo in the later post, easy to see.

    I should rephrase what I found in my particular situation, as I recreated it many times over.

    the -f 9999 does not create a backup of 3.1.5f with the 6.3b slices on it, and the -l will will backup the slices too.
