Use rsync for this purpose since cp cannot faithfully reproduce all the files that exist on OS X. The benefits of rsync over ditto and cp are: interrupted transfers can restart easily with very little cost. restarts even resume part way through a large file. file exclusion and --dry-run allow easy testing and iterative thinning. The simplest way to use ...

First thing I would like to comment on is "just reliable back-up of specific files." and you asking about Drobo RAID. RAID is not a BACKUP, RAID protects you against a physical drive failure, it doesn't protect against deletion, corruption, overwrites, etc. Just copying your files to a system with RAID (i.e. Drobo) isn't backing them up, it is just making a ...

You forgot to make an exclude-files list, and are likely copying things that can't / shouldn't be copied, including bottomless files like /dev/random. While cp can do the job, there are better tools. Rsync is one, Carbon Copy Cloner or SuperDuper is another. To use a kitchen analogy, you are using a knife to open a can. Rsync is a can opener, Carbon Copy ...

If you want to make a faithful copy of the filesystem contents, avoid using cp. Instead, use the ditto(1) command, which preserves hard links, file permissions, resource forks, and HFS metadata. Unlike cp, ditto is meant to preserve as much of that information as possible by default. It's just a matter of running sudo ditto src dest.

Just found an open source backup script Counterpart (jedda.me) which does exactly this, seemingly does stuff CCC misses too.

I have done this before and all I had to do was connect the HDD to the AirportExtreme and point Time Machine to the new location. I would recommend copying the backups from the drive to another drive if you can before doing so, there are some instances where Time Machine will reject the backups and then you will need to format the drive.

You can try unchecking "Put the hard disk(s) to sleep when possible" on System Preferences > Energy Saver (source). There's also an app that says it will give more detailed control called (appropriately) "Keep Drive Spinning". Here is a link to the developer site, the app sends you to macupdate for the download –be careful with bundled software on the ...

You might check out Transporter. It lets you attach a usb hard drive (or comes with one built in if you get that option) to your network and gives you a "private cloud" to store your files. Think of it as a Dropbox or Box like solution where you control the physical storage. They even let you connect them so if you have friends or family out of state you can ...

Make sure the driver is partitioned in GUID format. If you do elect to reformat it as GUID, this will erase your data. Also, network backups can only be encrypted before the first backup is carried out. Hover over the greyed out checkbox and I think you should be able to see an explanation.

I use an SanDisk Ultra miniDrive (64 GB) for transferable storage. However, I use an external hard drive to maintain Time Machine backups. Of note, for compatibility with Time Machine, the SD's default format (exFat) was incompatible, and I needed to use Disk Utility to reformat to Mac OS Extended (Journaled). For for information about SD cards, Apple ...

When two or more client access the TM service at the same time then a corruption can happen. TimeMachine on a TimeCapsule will create a lock when a backup takes places allowing only one backup being active at any time. Most third party implementations will not mark the TM as unavailable when another backup already is running. I have seen sparse bundle ...

To your first question: Yes it does keep record of lots of stuff--lots of records. Open the Console log and have fun looking through it. To your other questions: Only if you realize the mistake immediately some stuff is recoverable. It also depends how full your disk is (theoretically), so the deleted information would not be immediately overwritten.
