TM is perpetually connected (or often) to your computer, and corruption spread to corruption, without isolation, which TM lacks (usually), migrating errors or corruption is either automatic or extremely easy to unwittingly do.ĥ. Time machine mirrors your internal HD, in which cases of data corruption, this corruption can immediately spread to the backup as the two are linked. A HD clone is not subject to these errors.Ĥ.

This extra link of failure in placing software between your data and its recovery is a point of risk and failure. Time machine can and does have the potential for many error codes in which data corruption can occur and your important backup files may not be saved correctly, at all, or even damaged. Time machine is controlled by complex software, and while you can delve into the TM backup database for specific file(s) extraction, this is not ideal or desirable.ģ. Time Machine is not bootable, if your internal drive fails, you cannot access files or boot from TM directly from the dead computer.Ģ. Failure to look at one data in this matter is a failure which often can and does culminate in data loss.ĭata Storage Platforms their Drawbacks & Advantagesġ. Ones vital data must always be considered wholly independent and irrelevant of any data on the computer itself. External drives will invariably fail, and since most people falsely believe their external HD is their 'safety', this error of perspective must be countered by yet another external copy of ones data. Being the backup failsafe to the first external HD, not to the data on the computer which never should be counted in terms of data protection as 'a copy'.ģ. Any drive connected, backup or otherwise, is not to be considered a safe data redundancy.Ģ. Protected data redundancy begins at the second external copy due to:ġ. Only the second external HD is your first safe data redundancy. All data on the first external HD is your backup.ģ. All data on the computer is just that, your data.Ģ. Hard drives are cheap as dirt, your data is priceless, and your wifes data. Never make the HUGE mistake everyone else does, thinking a single external HD is a safe data backup Yourself as well, a SINGLE external data backup is by far the biggest mistake people make in general.

Which is why I and many dont use Itunes and Iphoto specifically.īut my wife has 16,000+ photos and growing! She is down to 50 gigs remaining on the 128 gig drive. The iphoto library has to be local on the drive as with itunes Mohr308 wrote:if its not on the drive you cant access them using iTunes or iPhoto.
