1/3/2024 0 Comments Chronosync sparse bundleWhen it comes to Mac-to-Mac syncing (assuming that we are talking about syncing over WiFi - there is also syncing in target disk mode, but that requires restarting on the of the computers, so it’s not my first choice), my biggest concern was what happens if I leave home in a hurry. That left me with either a personal cloud device or a Mac-to-Mac sync app. Fast sync sounds like it would solve my problem - but it has a bug such that it fails any time it encounters a zero-byte file, of which I have many (and so do you - for example, SQLite database stores, such as the Messages database, frequently include a zero-byte file). Portable Home Directories operate in one of two modes: slow sync (default), which works by having one computer scan the other for changes over AFP, and is (at my volume of data) unacceptably slow and fast sync (can be turned on from Terminal), which works by having one computer track changes locally so the other computer doesn’t have to actively scan for changes. I spent some time researching the OS X Server option, and learned that it’s completely useless. At that price, I can buy a Transporter and it will pay for itself in 3 years. I ruled out cloud file sharing right away the amount of data I have would put me in the $100-$200 per year Dropbox pricing tier. Cons: complex to set up, syncing away from home requires extra work. Pros: One-time purchase can sync app preferences. Use OS X Server and Portable Home Directories (PHD).Cons: Syncing when away from home requires extra work. Pros: Easy to set up can sync app preferences one-time purchase. Use a Mac-to-Mac sync utility, such as ChronoSync or Synk.Pros: Easy to set up network sync when away from home. Use a personal cloud device, such as Transporter.Cons: Doesn’t sync my app preferences requires substantial monthly fee for the amounts of data that I have. Use a cloud-based file sharing service, such as DropBox.I did some research and learned that my options were basically thus: In short, I want my computers to be convenient and my data to be safe. I want all my data to be backed up using Time Machine.I want to be able to leave home in a hurry, and sync my two computers while I am away from home (but not away from Internet access).I want my app preferences to be synced between the two computers.I want a subset of that data to be readily available on the portable computer, and I want to be able to choose what’s in that subset.I want all my data to permanently live on the desktop computer (where the large hard drive will be).Having recently switched to a dual-computer workflow (one desktop, for performance one laptop, for portability), I was not so much eager to find out how to make them work well together as I was sure I was facing a potentially frustrating adventure. Yes, a first world problem - but how hard could it be? ![]() Realistically, you should use a lengthy password with upper and lowercase letters, numbers and some punctuation, but don't make it something ridiculously long that you are likely to forget.Two macs, one person. They're just looking for a computer to use or sell, and will either wipe the hard drive or use it as-is without any conception of how to harvest what might be on the hard drive. Unless you're a likely target for serious industrial espionage, or something similar, and the data is of such high value that a thief might be trying to get your data and not your computer, an ordinary thief is not likely to have the patience or know-how to crack that encryption. ![]() (2) How long a password do you use? My understanding is that for AES-64 to by effectively immune to a brute force attack, the key needs to be 32 bytes? Is this not the case?ĭepends on how badly a thief might want your data. You can change it once you have unlocked it with the password, but you cannot reset it to gain access if you don't have the password. Resetting the account password does not reset the keychain password. Then make sure not to check the box to store the password in the keychain whenever you open that disk image.īTW, to answer your other question about the security of the keychain, note that unless someone can guess your password or manage a successful brute-force attack, they can't get in. In that case, you would just need to open Keychain Access, find that password and remove it. If it's not prompting you, the password has probably already been stored in the keychain. (1) How do you get OS X to prompt you for a password for an encrypted disk image (rather than having it stored in the keychain)?
