    Hi all
    I have actually two questions.
    I use a 2012 13" MBA with a 125GB ssd
    I just bought a 1TB ecternal (WD) and would like to use this as a storage HD for my Pictures +/- 400GB
    which file system should I use that TM can automatically back this volume up to my time capsule? Somebody told me i need to format to OS extended (journaled ). Is this correct?
    Secondly and equally important. Did Apple find by now a way around the 4GB file limitation. Many of my RAW panorama or focus stacks are bigger than 4GB and don't realy want to compress as this is even more time consuming!
    Would be nice to get answers to both questions.
    Txs in advance
    Guido:confused:

    Yes, Time Machine requires HFS+ formatted drives for backups.

    The 4GB per file limitation applies to FAT32 format, not HFS+.

    Format A Hard Drive Using Disk Utility (which is in your /Applications/Utilities folder)
    Choose the appropriate format:
    HFS+ (Hierarchical File System, a.k.a. Mac OS Extended (Journaled) Don't use case-sensitive) NTFS (Windows NT File System)
    • Read/Write NTFS from native Windows.
    • Read only NTFS from native Mac OS X [*]To Read/Write/Format NTFS from Mac OS X, here are some alternatives:
      • For Mac OS X 10.4 or later (32 or 64-bit), install Paragon (approx $20) (Best Choice for Lion and later)
      • For 32-bit Mac OS X, install NTFS-3G for Mac OS X (free) (does not work in 64-bit mode)
      • For 64-bit Snow Leopard, read this: MacFUSE for 64-bit Snow Leopard
      • Some have reported problems using Tuxera (approx $36).
      • Native NTFS support can be enabled in Snow Leopard and Lion, but is not advisable, due to instability.
    • AirPort Extreme (802.11n) and Time Capsule do not support NTFS
    • Maximum file size: 16 TB
    • Maximum volume size: 256TB
    • You can use this format if you routinely share a drive with multiple Windows systems.
    exFAT (FAT64)
    • Supported in Mac OS X only in 10.6.5 or later.
    • Not all Windows versions support exFAT. See disadvantages.
    • exFAT (Extended File Allocation Table)
    • AirPort Extreme (802.11n) and Time Capsule do not support exFAT
    • Maximum file size: 16 EiB
    • Maximum volume size: 64 ZiB
    • You can use this format if it is supported by all computers with which you intend to share the drive. See "disadvantages" for details.
    FAT32 (File Allocation Table)
    • Read/Write FAT32 from both native Windows and native Mac OS X. [*]Maximum file size: 4GB.
    • Maximum volume size: 2TB
    • You can use this format if you share the drive between Mac OS X and Windows computers and have no files larger than 4GB.
