実世界の例のRARのコマンド・ライン
毎週私は別の場所に私のWindowsのASRバックアップに2003のR2サーバーを、そのうちのいくつか物理的にいるする。
その事実のために私は私のオフィスにWAN上の私のデータを得る安全な方法について考えなければならなかった。
公正な平野のコピーは私の完全なASRバックアップ上の1ビット落下は屑であるかどうか私達がすべて知っているので選択ではない。
そして私は貴重な帯域幅を無駄にしよう。
私がと上がることができる解決はまたコマンド・ライン版があったことを私調べた明白で古いWinRarを使用することだった。
しかしその版と来る助けはちょっと秘密である。
次に私が都合した私のコマンド・ラインがある。
rar d:\asr - Bu \される\ asr_server.rar - ri1 - mt2 - ag [yyyy mmdd] - rv10 - v51200 - m5 d:\asr - Bu \ *.bkf
私は詳細のそれを説明する:
rar a d:\asr - Bu \される\ asr_server.rar - ri1 - mt2 - ag [yyyy mmdd] - rv10 - v51200 - m5 d:\asr - Bu \ *.bkf
a =アーカイブ、それにファイルを実際に話す私が考えるそれ自身のために加えなさい。
私達はアーカイブにファイルを加えようと思っている。
rar a d:\asr - Bu \される\ asr_server.rar - ri1 - mt2 - ag [yyyy mmdd] - rv10 - v51200 - m5 d:\asr - Bu \ *.bkf
d:\asr - Bu \される\ asr_server.rar =これは私達が作成しようと思っているアーカイブの名前である。
rar d:\asr - Bu \される\ asr_server.rar - ri1 - mt2 - ag [yyyy mmdd] - rv10 - v51200 - m5 d:\asr - Bu \ *.bkf
- ri1 =これは多くにアーカイブプロセスに最も低い1の優先順位を、この方法アーカイブ低下させないサーバーの性能を与える。
rar d:\asr - Bu \される\ asr_server.rar - ri1 - mt2 - ag [yyyy mmdd] - rv10 - v51200 - m5 d:\asr - Bu \ *.bkf
- mt2 = Multithreaded: 持っていればaはあなたが両方の糸の仕事を与えるこの命令を用いるCPUをそしてmultithreaded。
rar d:\asr - Bu \される\ asr_server.rar - ri1 - mt2 - ag [yyyy mmdd] - rv10 - v51200 - m5 d:\asr - Bu \ *.bkf
- ag [yyyy mmdd] =ここにアーカイブに[2007-11-22]それに付けられるを用いる名前を与える。
rar d:\asr - Bu \されて\ asr_server.rar - ri1 - mt2 - ag [yyyy mmdd] - rv10 - v51200 - m5 d:\asr - Bu \ *.bkf
- rv10 =これは私のため最も重要な選択である: このスイッチは何REVが作られるか数が示すREVファイルと呼ばれる回復ボリュームを作成する。
rar d:\asr - Bu \される\ asr_server.rar - ri1 - mt2 - ag [yyyy mmdd] - rv10 - v51200 - m5 d:\asr - Bu \ *.bkf
- v51200 =ここに私達はrarアーカイブ(私達はいくつかのアーカイブに及ぶの最高のサイズをアーカイブを作成している指定する。 探検家(1024×50)で50.000 KBとしてきちんと示すので第51200は選んだある
rar d:\asr - Bu \される\ asr_server.rar - ri1 - mt2 - ag [yyyy mmdd] - rv10 - v51200 - m5 d:\asr - Bu \ *.bkf
- m5 =これは圧縮のレベル5をである最高の圧縮0である全然ちょうど店圧縮いかに指定しないかである。
rar d:\asr - Bu \される\ asr_server.rar - ri1 - mt2 - ag [yyyy mmdd] - rv10 - v51200 - m5 d:\asr - Bu \ *.bkf
d:\asr - Bu \ *.bkf =ここに私達は何を私達が作成するアーカイブで貯えればいいのか指定する。 My ASR backup is stored at this location, I use also a date in my naming of ASR’s so I must use a wildcard here.
All of this results in the following set of rar files
asr_server[2007-11-22].part001.rar
asr_server[2007-11-22].part002.rar etc…
I hope this helps you.

Thanks for the nice article. I am going to try this to satisfy an off-site backup requirement for our 15GB (and growing) Exchange server backups, which are currently sent on tape via currier every morning. The one thing I would most like to know is what kind of compression ratio can you get when archiving a BKF file? Across my WAN I have calculated that I can transfer about 1.5GB per hour, which means every single offsite backup of my Exchange server will take about 22.5 hours to move across the T1 link, more as time goes on and the database increases in size. I am hoping I can compress it down a LOT, but I have doubts because I think BKF’s are already somewhat compressed. Thanks again!
