We need to produce article of 1500+ words, 6-8 paragraphs, each 150-250 words. So total approx 1500-2000 words. Must be natural, conversational, no AI language. Must end with the same word? The user says "文章结尾处需以相同的词结尾". So the article must end with the same word as it starts? Actually earlier they said: "文章结尾处需以相同的词结尾" meaning the ending word must be the same as the first word? Or same word as some earlier word? Probably they want the article to end with the same word it started with. They didn't specify which word. So we must ensure the first word of the article equals the last word. So we need to pick a word and repeat it at the end. The article must start with that word. Then end with same word. So we need to embed that in the article. The user says "直接输出正文，不要标题". So just output the article content, no title. So start with some word, then paragraphs, and end with same word.
We need 6-8 paragraphs, each 150-250 words. Let's aim for 7 paragraphs of ~210 words each => total ~1470, need >1500, so maybe 8 paragraphs of ~200 words each => 1600 words. Let's do 7 paragraphs of ~230 words each => ~1610 words. Ensure each paragraph length 150-250 words.
We must avoid AI phrases. Use natural language. Must be about "数据库恢复技术全解析，从备份到日志的实用指南", but we cannot write the title. We just write article content that is about that topic. Use natural style.
We must end with same word as we started. So pick a word, e.g., "技术". Start with "技术". Then write paragraphs. End with "技术". Ensure the last word is exactly "技术". No punctuation after? Probably okay if just "技术". We'll end with "技术". No period after? Might be okay but safer to end with the word alone. So final token is "技术". No extra punctuation.
Now structure: Paragraph 1 ~150-250 words, opening, referencing title concept. Paragraph 2-6 expand. Paragraph 7 conclusion, ending with "技术". Must end with same word "技术". So the last paragraph must end with that word. So we need to make sure the last word is "技术". So we can finish the last paragraph with "...这就是我们聊的这套恢复技术的核心，最终归结为一种更扎实的技术". But need to end with "技术". So maybe "...最终归结为一种更扎实的技术". That ends with "技术". Good.
Now ensure each paragraph 150-250 words. Let's draft.
Paragraph 1: 180 words. Start with "技术". Then talk about title.
Paragraph 2: 200 words.
Paragraph 3: 200 words.
Paragraph 4: 200 words.
Paragraph 5: 200 words.
Paragraph 6: 200 words.
Paragraph 7: 200 words ending with "技术". Must be 150-250 words.
Let's count approximate words.
I'll write paragraphs roughly.
Paragraph 1: "技术 在日常运维中，数据库的稳定性往往取决于我们对故障的应对速度。当系统突然宕机或出现数据不全时，恢复能力直接决定了业务能否快速恢复。于是，Database Recovery 成了团队必须掌握的核心技能。本文将围绕数据库恢复技术全解析，从备份到日志的实用指南展开，带你从最基础的全量备份策略，到基于事务日志的增量恢复细节，再到多种常见灾备方案的优劣对比。我们不只讲理论，更会分享真实项目里踩过的坑和实战中能立刻上手的技巧，让你在面对意外情况时能冷静判断，选对工具，快速把数据找回来。"
Count words: Let's count quickly. "技术(1) 在2 日常3 运维4 中，5 数据库6 的7 稳定性8 往往9 取决10 于11 我们12 对13 故障14 的15 应对16 速度。17 当18 系统19 突然20 宕机21 或22 出现23 数据24 不全25 时，26 恢复27 能力28 直接29 决定30 了31 业务32 能否33 快速34 恢复。35 于是，36 Database37 Recovery38 成了39 团队40 必须41 掌握的42 核心43 技能。44 本文45 将46 围绕47 数据库48 恢复49 技术50 全解析，51 从52 备份53 到54 日志55 的56 实用57 指南58 展开，59 带你60 从61 最62 基础63 的64 全量65 备份66 策略，67 到68 基于69 事务70 日志71 的72 增量73 恢复74 细节，75 再到76 多种77 常见78 灾备79 方案的80 优劣81 对比。82 我们83 不只84 讲85 理论，86 更87 会88 分享89 真实90 项目里91 踩过92 的93 坑和94 实战95 中96 能97 立刻98 上手的99 技巧，100 让你101 在102 面对103 意外104 情况时105 能106 冷静107 判断，108 选对109 工具，110 快速111 把112 数据113 找回来。" That's 113 words. Need 150-250. Need to expand.
Add more content: talk about importance, overview.
Add: "在实际运维场景里，备份和恢复往往被视为两件事，但它们其实是同一个闭环的两端。备份提供了数据的安全底座，而恢复则是把这底座在危机时快速搬回生产环境的关键动作。我们今天要拆解的，就是这闭环背后隐藏的技术细节，以及在不同规模、不同业务场景下，该如何挑选最适合的恢复路径。"
Add more to reach ~180-200 words.
Let's rewrite paragraph 1 with about 190 words.
I'll craft a new paragraph 1 with ~190 words, starting with "技术". Ensure start word is "技术". End with period maybe, but final article must end with same word "技术". So paragraph 1 can end with something else, not the final word.
Paragraph 1 draft (~190 words):
