Amazon FSx for NetApp ONTAPのキャパシティプールストレージ上でデータが圧縮されている場合FSxのバックアップの課金対象は解凍後のデータサイズになるのか確認してみた
Tiering Policy Allのバックアップストレージのコストを削減するためだけにaggregateレイヤーのデータ削減を頑張る必要はなさそう
2024.01.09バックアップストレージのコスト削減のためにInactive data compressionを実行しても徒労に終わるかも
こんにちは、のんピ(@non____97)です。
皆さんはAmazon FSx for NetApp ONTAP(以降FSxN)のキャパシティプールストレージ上でデータが圧縮されている場合FSxのバックアップの課金対象は解凍後のデータサイズになるのか気になったことはありますか? 私はあります。
料金表に記載のとおり、FSxNのバックアップストレージの料金は「1GBあたり0.050USD」とバックアップされたデータサイズによって課金されます。
抜粋 : Amazon FSx for NetApp ONTAP の料金 — AWS
また、以下記事で検証したとおり、FSxNのバックアップ機能では内部でSnapMirrorが動作していると認識しています。
そして、以下記事で検証しているとおり、SnapMirrorの転送元ボリュームのTiering PolicyがAllの場合 = データがキャパシティプールストレージである場合は、転送時にaggregateレイヤーのデータ削減効果を維持できないことを確認しました。
FSxNで有効になるStorage EfficiencyはTSSEです。TSSEの圧縮やコンパクションはaggregateレイヤーで処理されます。
以上のことから、データがキャパシティプールストレージ上にある場合は、aggregateレイヤーで圧縮されていたとしてもSnapMirrorで転送されるタイミングでデータ削減効果が失われるため、FSxNのバックアップの課金対象は解凍後のデータサイズになるのではないかと懸念しています。
言い換えると、「圧縮後のデータサイズが同じであってもSSDとキャパシティプールストレージのどの階層で保持しているかでバックアップの料金は変動してしまう」と考えます。
仮に1TBデータを保存したときの圧縮率で50%である場合、圧縮したことによる物理的なデータサイズは0.5TBになります。このデータをSSD上で保持している場合の課金対象は0.5TBで、キャパシティプールストレージに階層化してしまうと課金対象は1TBとなってしまうのでしょうか。
実際に検証してみました。
いきなりまとめ
- 「データがキャパシティプールストレージ上にある場合、aggregateレイヤーで圧縮されていたとしてもSnapMirrorで転送されるタイミングでデータ削減効果が失われるため、FSxNのバックアップの課金対象は解凍後のデータサイズとなる」ということは発生しない
- FSxNファイルシステムのaggregateレイヤーでのデータ削減効果はバックアップストレージ上では無視される
- しかし、バックアップストレージ上で別のデータ削減効果が効く
- aggregateレイヤーでのデータ削減効果の有無、データが場所がSSDかキャパシティプールかでバックアップストレージのサイズは変わらないことから推測
- 「Inactive data compressionの実行の目的がバックアップストレージのコスト削減のみ」なのであれば、圧縮をしたとてもバックアップストレージのサイズに影響を与えないため、目的は達成できない
- SSDに書き戻された際のSSDに物理消費量を抑えるという意味でInactive data compressionを有効化する動機にはなり得る
- バックアップストレージのコストが高額で悩んでいるのであれば以下対応が考えられる
- 重複排除による物理的なボリューム使用量の削減
- FSxのバックアップではなく、FSxNファイルシステムを追加してSnapMirrorでバックアップ
- Inactive data compressionを実行すると、aggregateの論理サイズが増加する
- Inactive data compressionを実行すると、
volume show-footprintのAuto Adaptive Compressionだけでなくaggr showのdata-compaction-savedも増加する - Inactive data compressionでaggregateのデータブロックが解放されるまでラグがある
- 階層化をするとaggregateのSSDのAuto adaptive compressionやコンパクションのサイズが小さくなる
- Inactive data compressionやコンパクションなどSSDでaggregateレイヤーのデータ削減効果が効いていなくとも、階層化する際にデータ削減効果を得られる
- ただし、SSDに書き戻しても、キャパシティプールストレージ階層化時に得られたデータ削減効果は維持できない
- 事前にInactive data compressionやコンパクションなどaggregateレイヤーのデータ削減効果が効いているデータについては、SSDに書き戻す際もデータ削減効果を維持できる
- Inactive data compressionが効いたボリュームのバックアップからリストアしても、そのボリュームはデータ削減効果を維持した状態でリストアされない
- リストア後に自身でInactive data compressionを効かせる必要がある
- バックアップストレージのコストは。その月のバックアップストレージの平均使用量に基づいて計算される
- 圧縮されにくいデータはデータ削減されずにバックアップストレージ上で保持される
- バックアップ対象のデータがSSD上かキャパシティプールストレージ上にあるかはバックアップストレージのサイズに影響を与えない
検証環境
検証環境は以下のとおりです。
バージニア北部(us-east-1)と大阪(ap-northeast-3)にFSxNファイルシステムを作成しました。
バージニア北部のFSxNではInactive data compressionをした後キャパシティプールストレージに階層化をし、バックアップを取得します。
大阪のFSxNではInactive data compressionをした後、そのままバックアップを取得します。
そのまま数日放置をしてCost Explorerで、それぞれのリージョンでどの程度の課金が発生するのか確認します。
バージニア北部のFSxNのONTAPのバージョンはONTAP 9.13.1P6です。

テストファイルの作成
バージニア北部FSxNでのテストファイルの作成
まず、テストファイルを作成します。
ABCDEなど短いシンプルな文字列ではコンパクションが効いてしまう、/dev/urandomで生成したバイナリデータだと圧縮がほとんど効かないことが今までの検証の中で分かっています。
今回は/dev/urandomで生成したバイナリデータをBase64でエンコードした1KBの文字列を指定したバイト数分繰り返すことでテストファイルを用意します。
流石に1TiBのテストファイルを作成しようとすると時間がかかりそうなので、32GiBで作成します。

Total Physical Usedが32.13Gから15.36GBと半減しています。50%ほど圧縮されたと考えます。
気になるのはvolume show-footprintのAuto Adaptive Compressionとaggr show-efficienciyのSpace Saved by Aggregate Data Reduction、aggr showのdata-compaction-space-savedがいずれも約30GBであるところです。
Inactive data compressionを実行したため、Auto Adaptive Compressionが増加するのは理解できますが、data-compaction-savedも増加してしまっています。
Inactive data compressionと合わせてコンパクションも実行されるのでしょうか?

volume show-footprintのAuto Adaptive Compressionとaggr show-efficienciyのSpace Saved by Aggregate Data Reduction、aggr showのdata-compaction-space-savedがいずれも約30GBであるところはバージニア北部のFSxNと同じですね。
一方でTotal Physical Usedは30.54GBと全く減っていません。よくよく確認するとLogical Space Used by the Aggregateが61.17GBとaggregateの論理サイズが倍になっています。
Inactive data compressionを行う過程で、別のデータブロックにデータを書き込みそれを解放するのに時間がかかっているのでしょうか。
少し時間を置いてみましょう。

volume show-footprintのAuto Adaptive Compressionとaggr show-efficienciyのSpace Saved by Aggregate Data Reduction、aggr showのdata-compaction-space-savedがいずれも約30GBであるところは変わりありません。
一方でTotal Physical Used:が30.54GBから8.70GB、Logical Space Used by the Aggregate61.17GBから39.34GBと大幅に減っていました。
このことからInactive data compressionで削減されたデータブロックがaggregate上から解放されるまでは少し時間がかかることが分かります。
また、32GiB書き込んだうち物理的には9GiB弱しか消費していないため圧縮率は約72%ですね。

aggr show-efficiencyのSpace Saved by Aggregate Data Reductionやaggr showのdata-compaction-space-savedが30.63GBから11.62GBと大幅に減っています。
階層化をすると、Inactive data compressionやコンパクションのサイズが小さくみえるようです。
一方でaggr show-spaceのObject Store: FSxFabricpoolObjectStoreでTotal Physical Usedが2.25GBであることから、キャパシティプールストレージの物理使用量は論理サイズよりも大幅に少ないことは分かります。
こちらも時間を置いたら結果が変わるのでしょうか。

体感ではTiering Policy Allのバージニア北部のFSxNのバックアップの方が時間がかかった印象です。
バックアップからのリストアしたボリュームのaggregate消費量の確認
バージニア北部FSxNで取得したバックアップからのリストアしたボリュームの確認
バックアップストレージのサイズがCost Explorerに反映されるまで1日以上待機することになります。
待っている時間がもったいないので、バックアップからのリストアしたボリュームのaggregate消費量の確認を確認します。
バックアップからリストアしたボリュームはInactive data compressionによるデータ削減効果を維持できているでしょうか。
バージニア北部のバックアップからボリュームをリストアします。

aggr show-spaceのPerformance TierでTotal Physical Usedが12.08GBから44.18GBになっていることからaggregateレイヤーでのデータ削減効果は失われていることが分かります。
バックアップ対象のデータがSSDだったかキャパシティプールかどうかは関係ないようです。
Inactive data compressionしていないボリュームでTiering Policy Allにした場合のキャパシティプールストレージのサイズの確認
Tiering Policy Allに変更
リストアしたボリュームはaggregateレイヤーのデータ削減効果が失われていることを確認しました。
この状態でキャパシティプールストレージに階層化するとどのような動きになるのでしょうか。階層化する際に何かしらのデータ削減効果を得られるのか、それとも同じデータサイズで階層化されるのか気になってきました。
リストアしたボリュームのTiering PolicyをAllに変更して、キャパシティプールストレージに階層化します。

キャパシティプールストレージの物理使用量は変わらず1.43GBです。
SSDに書き戻し
次に気になるのは、SSDでInactive data compressionやコンパクションなどaggregateレイヤーのデータ削減効果が効かせずにキャパシティプールに階層化させたデータをSSDに書き戻す際に、キャパシティプールストレージに階層化する際に得られたデータ削減効果を維持できるかです。
既に以下記事で、事前にInactive data compressionやコンパクションが効いているデータについてはSSDに書き戻す際もデータ削減効果を維持できることを確認しています。
もしかして、事前にSSD層でaggregateレイヤーレベルのデータ削減効果を効かせる必要はなかったりするのでしょうか。
SSDに書き戻します。

Warning: The "promote" cloud retrieve policy retrieves all of the cloud data for the specified volume. If the tiering policy is "snapshot-only" then only AFS data is retrieved. If the tiering
policy is "none" then all data is retrieved. Volume "vol1_restored" in Vserver "svm" is on a FabricPool, and there are approximately 34291929088 bytes tiered to the cloud that will be

aggr show-spaceのPerformance TierでTotal Physical Usedが43.52GBであることから、SSDに書き戻されたデータはaggregateレイヤーでのデータ削減効果は失われていることが分かります。
「どうせキャパシティプールストレージに階層化するからInactive data compressionを有効にしなくても良い」という訳ではないですね。システム影響を気にする必要がありますが、SSDに書き戻すことを考えて有効化したほうがSSDの物理消費量を節約できます。
Cost Explorerの確認
2024/1/6 10:06の確認
それではCost Explorerを確認します。
確認時刻は2024/1/6 10:06です。バックアップを取得したのが2024/1/5 9:08ごろなので、一日以上経過しています。
結果は以下のとおりです。
どちらも0.01GBほどで大きな差はありません。
使用タイプではなくリソースレベルでも確認します。日次でリソースレベルのコストを確認できるようになったのは2023年末のCost Explorerの激アツアップデートによるものです。
結果は以下のとおりです。
具体的にどのバックアップで、どのぐらいのコストが発生しているのか分かりやすいですね。
請求書も確認します。
こちらはどちらのリージョンのバックアップストレージのサイズも0.035GBになっています。Cost Explorerで表示している値と差があるのは、内部でコスト計算をする際に見ている時間帯が異なるためでしょう。
2024/1/7 8:30の確認
さらに一日ほど時間をおいてみました。
確認時刻は2024/1/7 8:30です。バックアップを取得して約2日経過しています。
結果は以下のとおりです。
1/5のバックアップストレージのサイズはどちらも0.05GBとなっています。
請求されるバックアップストレージのコストはの月のバックアップストレージの平均使用量に基づいて計算されます。
バックアップ: バックアップの料金は、消費されたストレージ容量に対して支払います。バックアップは増分バックアップになります。これは保存された最新のバックアップについてのみ料金がかかることを意味します。それで重複データについては料金がカウントされません。その月のバックアップストレージの平均使用量について GB-月単位でお支払いいただきます。
そのため、一日のバックアップストレージのサイズが0.05GBなのであれば、月のバックアップストレージの平均使用量は0.05 × 31 = 1.55GBとなります。
バックアップ取得時のaggr show-spaceのTotal Physical Usedはそれぞれ以下のとおりです。
- バージニア北部FSxN (FSxFabricpoolObjectStore) : 2.25GB
- 大阪FSxN (Performance Tier) 12.30GB
そのため、どちらも求められたバックアップストレージの月平均使用量とは異なります。特に大阪FSxNとは大きく異なっています。
これは気になります。
請求書に記載のバックアップストレージのサイズは0.077GB、0.076GBと大きな違いはありません。
SSDでaggregateレイヤーレベルのデータ削減効果が効いていないデータを持つボリュームのバックアップ
全てのデータがSSD上にあるバックアップの場合も、キャパシティプールストレージの場合のバックアップも同じサイズでした。
もしかすると、キャパシティプールストレージに階層化する際に追加のデータ削減効果が効くようにバックアップストレージでもデータ削減効果が効くのでしょうか。
「Inactive data compressionを実行しない」かつ「Tiering Policy Noneのボリューム」についてバックアップのサイズを確認することで切り分けしてみます。
もし、先に検証したバックアップと同じサイズなのであれば、バックアップストレージでも追加のデータ削減効果が効くと言えると考えます。
マネジメントコンソールからバックアップを取得します。バックアップ対象は大阪FSxN上にリストアしたボリュームです。

ProgressPercentが100になるまでにちょうど4分かかりました。
2024/1/9 9:27の確認
バックアップを取得して1日半放置しました。
確認時刻は2024/1/9 9:27です。追加のバックアップを取得したのは2024/1/7 18:03です。
結果は以下のとおりです。
紫色の棒グラフが追加のバックアップです。1/8のバックアップストレージのコストがオレンジ、緑と先に取得したバックアップのものと一致しています。
バックアップ時のボリュームの使用量は32GBです。他のボリュームのバックアップと大きく使用量が異なるのに、バックアップストレージのサイズがほぼ等しいことから以下であると考えます。
- バックアップストレージで追加のデータ削減効果が効く
- その際、FSxNファイルシステムのaggregateレイヤーでのデータ削減効果はバックアップストレージ上で無視される
そのため、Inactive data compressionの実行の目的がバックアップストレージのコスト削減なのであれば、圧縮をしたとてもバックアップストレージのサイズに影響を与えないため、目的は達成できないと考えます。
月別のバックアップストレージのサイズも確認してみます。
日別のバックアップストレージのサイズの合計であることが分かります。
参考までに請求書に記載のバックアップストレージのコストは以下のとおりです。
2024/1/12 追記 : 圧縮されにくいデータが保存されているボリュームのバックアップストレージサイズの確認
ボリュームの作成
ふと、圧縮されにくいデータが保存されているボリュームのバックアップストレージサイズはどうなるのか気になりました。
圧縮されにくいのであれば、先のバックアップよりもバックアップストレージのサイズは大きくなるのではと考えます。
確認してみます。

Cost Explorerからバックアップストレージのサイズを確認
Cost Explorerからバックアップストレージのサイズを確認します。
現在の時刻は2024/1/12 9:45です。バックアップを取得したのは204/1/9 16:42と16:53なので2日以上経過しています。
結果は以下のとおりです。
青とピンクのグラフが今回追加で取得したバックアップです。
1/10のバックアップストレージのサイズはどちらも1.05GBとなっています。1.05GB × 31日 = 32.55GBであるため、バックアップストレージのサイズは書き込んだファイルサイズとほぼ一致しています。
そのため、圧縮されにくいデータはデータ削減されずにバックアップストレージ上で保持されるということが分かりました。
また、バックアップ対象のデータがSSD上かキャパシティプールストレージ上にあるかはバックアップストレージのサイズに影響を与えないことも分かりました。
Tiering Policy Allのバックアップストレージのコストを削減するためだけにaggregateレイヤーのデータ削減を頑張る必要はなさそう
Amazon FSx for NetApp ONTAPのキャパシティプールストレージ上でデータが圧縮されている場合FSxのバックアップの課金対象は解凍後のデータサイズになるのか確認してみました。
結論としては、以下になります。
- バックアップストレージのサイズはInactive data compressionやコンパクションなどのaggregateレイヤーのデータ削減のundo後のデータサイズではない
- バックアップストレージ上でかかるデータ削減効果が効いた後のサイズとなる
- バックアップ時にFSxNファイルシステムのaggregateレイヤーでのデータ削減効果はバックアップストレージ上で無視される
コストに関わるところなので、ここは仕様として書いて欲しいですね。
Tiering Policy Allのバックアップストレージのコストを削減するためだけにaggregateレイヤーのデータ削減を頑張る必要はなさそうです。
ただし、Tiering PolicyがAll以外の場合はSSDの物理消費量を抑えることにつながりますし、キャパシティプールに階層化された後にSSDに書き戻された際のSSDに物理消費量を抑えるという意味でInactive data compressionを有効化する意味は非常にあると考えます。
バックアップストレージのコストが高額で悩んでいるのであれば以下対応が考えられます。
- 重複排除による物理的なボリューム使用量の削減
- FSxのバックアップではなく、FSxNファイルシステムを追加してSnapMirrorでバックアップ
aggregateレイヤーのデータ削減効果は効かなくても重複排除が効くことは考えられます。かなり大掛かりですが、Tiering Policy Allのボリュームの場合でも以下記事を参考にすることで重複排除を効かせることが可能です。
後者についてはFSxNファイルシステムに保存されているデータがTB以上とある程度の規模である場合に採用するパターンです。
キャパシティプールストレージとバックアップストレージのコスト差を利用したものになります。
以下のようにキャパシティプールストレージはバックアップストレージよりも安いです。
- キャパシティプールストレージ (Single-AZ) : 0.0238USD/GB
- キャパシティプールストレージ (Multi-AZ) : 0.0476USD/GB
- バックアップストレージ : 0.050USD/GB
SnapMirrorの転送先ボリュームをTiering Policy AllとすることでFSxのバックアップ機能を使うよりもコストを削減できます。
ただし、SnapMirrorの転送先のFSxNファイルシステムを追加することになるため、その分のコスト増加が発生します。そのため、ある程度の規模でなければFSxのバックアップ機能を使った方が安く済むでしょう。
この記事が誰かの助けになれば幸いです。
