 <sect id="backup">Necessary actions prior to the upgrade
 <sect id="backup">升級前所需事項

  <p>極之推薦在升級之前,把系統完全復制備份, 或最少把你不能替代的資料及配置檔
  復制備份. 雖然升級程式及過程是十分穩定可靠, 但硬件在升級中途失控亦會嚴重損
  害系統.

  <p>Before upgrading your system, it is strongly recommended that you make
  a full backup, or at least, backup any data or configuration information
  you can't afford to lose. The upgrade tools and process are quite
  reliable, but a hardware failure in the middle of an upgrade could result
  in a severely damaged system.

  <p>最主要及必需復制備份的檔案, 包括 <file>/etc</file>,
<file>/var/lib/dpkg</file>
  和 <tt>dpkg --get-selections</tt> 的輸出.

  <p>The main things you'll want to save are the contents of <file>/etc</file>,
  <file>/var/lib/dpkg</file> and the output of <tt>dpkg --get-selections</tt>.

  <p>預早通知用戶系統升級的計劃是明智的, 雖然用戶經由 ssh 進入系統, 在升級途
  中應不會發覺多大變動, 並有可能希望繼續使用. 如果想加倍小心, 在升級前你亦可
  把用戶的區分 (<file>/home</file>) 卸下或復制備份.

  <p>It's wise to inform all users in advance of any upgrades you're
  planning, although users accessing your system via ssh (at least)
  shouldn't notice much during the upgrade, and may want to continue
  working. If you wish to take extra precautions, back up or unmount
  user's partitions (<file>/home</file>) before upgrading.
