Hej.
Jag äger en Qnap TS-439 Pro II+. I denna har jag 4x2TB Seagate 5900rpm. Dessa kör jag i RAID 5 och har gott om plats kvar på diskarna. Men jag upplever den som väldigt långsam. Skrivhastigheten har aldrig kommit över 18MB/s, och jag funderar ibland på om det är en USB 2-disk jag sitter på, trots att den är kopplad via Gb-lan.
Om man kikar på Macworlds test av Qnap TS-259 Pro+ så presterar den en skrivhastighet på 64MB/s och en läshastighet på 87MB/s. Tyvärr står det ju inte om de kör diskarna i RAID 0 eller RAID 1, samt hur stora filerna är, otroligt dåligt!
Släng servern - låt nas:en ta över - MacWorld
Men vad säger ni andra med erfarenhet av NASar? Jag upplever den som rejält trött och funderar på att sälja den och skaffa något annat i stället.
Så finns det någon som har något klokt råd att ge, inte på nya enheter, utan på vad som kan vara problemet med min nuvarande burk? ALLA tips mottages tacksamt!
The difference between Syncing and Backing up:
When you need to use files on both locations - the source and the destination - you should synchronize them. Files get copied from a source to a destination and then back again.
You backup files when you need to use files in one location but want a backup of the files in a second location in case something goes wrong. When backing up, files get copied from a source to a destination. You typically never use the files on the destination other than to restore them to the source.
So what have learned? Your Mac has a hard drive. On the hard drive you have a bunch of files. All the users on the Mac have a Home folder with all their files in it. When you synchronize or backup, you are simply copying files from one location to another. The two sections below point you in the right direction for setting up ChronoSync to synchronize and/or backup.
Sync It!
You should synchronize any data you need to access on other devices like other Macs, iPhones, iPods, or even PCs.
You don't want to synchronize System or Library files outside of your Home folder because these files can vary from Mac to Mac. You don't want to synchronize Applications because all Applications should be installed and updated from an installer or Software update. You should only synchronize files in your Home folder and, more importantly, you should only synchronize some of the files in your Home folder using ChronoSync. There is some Managed Data inside your Home folder you should not sync using ChronoSync. Managed Data are files in your Home folder that are structured into databases like your Address Book, iTunes, iPhoto and Bookmarks. To learn the basics of synchronizing, read the tip Quick Setup and to learn how to sync your Home folder, read the tip Syncing your Home Folder.
If you want to find out more information on synchronizing your Managed Data then get the book Take Control of Syncing Data in Snow Leopard by Michael Cohen.
NOTE: In some circumstances it may be fine to synchronize files outside of your Home folder. This usually only the case if you are dealing with servers or unique situations. This should only be done by the advanced Mac user. So if you do need to synchronize files outside of your Home folder contact us to go over your scenario.
Back it Up!
Unlike synchronizing, which limits what files you can sync, you can (and should!) back up all the files on your Mac. If you fail to regularly do this, eventually you may be one of those people we all hear about who lost their data because they were not diligent about backing up. You can backup to internal drives, external drives, Macs, PC's, iPods, iPhones, or web storage. Many people use Time Machine to backup their Mac and if you do that you are better off than most who do not even backup at all. However, Time Machine does have some limitations that ChronoSync does not have.
First, it can only back up your Mac. It cannot back up data stored in other locations, like external drives. Second, it cannot make a bootable backup. Third, and most notably, Time Machine stores the files it backs up in proprietary format. That means you can only view and restore backed up files using Time Machine. ChronoSync store files exactly in the same way on the destination as on the source. That means you can view and restore backed up files without ChronoSync. So what you see on your Mac is exactly what you see on your backup. In fact, this is the main reason why so many users like ChronoSync for backing up.
ChronoSync does have one limitation that Time Machine does not. Although ChronoSync archives deleted and changed files, it does not have the ability to restore these files by a specific time like Time Machine can. Instead, ChronoSync allows you to restore older files by file version. So every time a file gets deleted or changes, ChronoSync archives the older version in case you need it again. To learn the basics of backing up read the tip Quick Setup and to learn all about bootables read the tip Creating a Bootable Backup.
