Adjust your backup settings

# Settings

# Automatic backups

Turn this option on to have Déjà Dup automatically back up for you. This is recommended so that you don’t forget to do it yourself. Backups are more useful the more recent they are, so it is important to regularly back up.

# Backup location

Use these options to specify the backup location that Déjà Dup will use when backing up or restoring:

# Cloud Services

The first few backup locations are cloud storage services provided by various companies. For a small fee, they hold your data for you. A cloud service like this is recommended because it is an easy way to keep your data offsite (meaning out of your home: in case of disaster or theft, your data will still be safe).

These services costs money. Read their rates carefully before using them.

# Remote Servers

Choose the type of remote server to which you want to connect. Then you can enter the server information. Alternatively, if you know your server’s URL, choose Custom Location and enter it.

# 可移动媒体

您可能会在列表中看到外置硬盘或闪盘之类的可移动媒体。

# Local Folder

您可能还想选择一个本地文件夹作为备份位置。请注意，备份的体积可能相当大，因此请确保您拥有足够的可用磁盘空间。

This is not recommended, because if your hardware fails, you will lose both your original data and your backups.

# Folders to back up

Choose a list of folders to back up. Press the Add or Remove buttons to modify the list. If you are only interested in backing up your own data, the default of Home is sufficient.

# Folders to ignore

Choose a list of folders to not back up. Press the Add or Remove buttons to modify the list.

您的一些数据可能体积庞大，并且对您而言不是非常重要。如果是这样，不备份它们可以为自己节省一些时间和空间。

Some locations are always ignored by default:

~/.adobe/Flash_Player/AssetCache

~/.cache

~/.gvfs

~/.Private

~/.recent-applications.xbel

~/.recently-used.xbel

~/.thumbnails

~/.xsession-errors

/proc

/sys

/tmp

# Keep backups

选择备份文件的最短保留时间。如果您发现备份文件占用的空间过多，可能想缩短这段时间。由于实现细节上的缘故，文件的保留期可能比选择的时间略长。但不会有任何文件被提前删除。

Backups are kept forever by default, but still may be deleted earlier if the backup location begins to run out of space.
