    Hello all

    I’ve searched the internet without any success, so now I turn to you gurus for help.

    I run a small network only consisting macs. Every mac have time machine set up to backup to a NAS Synology server, which means there is a user registered to each mac on the server.

    I’m about to upgrade two users with new MacBook airs, and I don’t want to set these macs up with a four year old time machine backup filled to the edge with old files and what not.
    However, I still want to set up time machine on the same username.

    So, the big question is: If I create a new time machine backup on the same username that back up the old mac on this new MacBook air, will the old backups be deleted?
    Or will the backup-line continue?

    I am too afraid to just try it out and see what happens because, you know; I’m guessing there is no turning back once these files get overwritten.

    Thanks in advance,
    - Sig

    I suppose that for each user Time Machine creates a bundle with the name of the Mac. So, I suppose that if the new Macs have different names, you will not overwrite the other time machines backups.

    hmm

    Do you know what would happen if I did this on the same mac?
    A couple of weeks ago I formatted a mac and re-installed everything due to slowness. I did not dare take the risk so I made a new user just in case.

    i know when I did a reformat and didn't set up from a backup, time machine just created a new sparsebundle And i used the same username and everything

    for example

    MacBook Pro (original file)
    MacBook Pro 1 (new file after reformat)

    The results

    You guys where right!

    I just went ahead and did a Time Machine backup on this new MacBook Air, and a new bundle appeared on my NAS server. Nothing got overwritten.

    Thanks! :D

    The issue of "proof in the pudding" will be when you attempt a restore. I'm truly hoping the best for you and your backups.
