Hello, Hope this letter finds you well. Could you please help me with a question that i have. My question is about the generation of several segment files are incremented on a Node. I used elastic 6.8.12 and I have the infrastructure replicated in two nodes (node A, node B). Now the size of nodes are: **Node A:** /usr/share/Elasticsearch/data/backups/snap\_repo/indices 12 GB **Node B:** /usr/share/Elasticsearch/data/backups/snap\_repo/indices 223 GB the size of backup in node B is bigger than node A but both nodes should be the same size o similar. I revides the files. Why it is generated several segment files **`__** `** in node B, but no in node A?. This is the reason for the different size between nodes. Please find a short exemple below, in general the number of files are very big. Node B: **/usr/share/Elasticsearch/data/backups/snap\_repo** -rw-rw-r-- 1 Elasticsearch Elasticsearch 12K Dec 15 22:50 meta-GtSrbA44STaweZjEH5On9w.dat -rw-rw-r-- 1 Elasticsearch Elasticsearch 900 Dec 15 23:25 snap-GtSrbA44STaweZjEH5On9w.dat -rw-rw-r-- 1 Elasticsearch Elasticsearch 24K Dec 15 23:25 index-1260 -rw-rw-r-- 1 Elasticsearch Elasticsearch 23K Dec 15 23:25 index-1261 -rw-rw-r-- 1 Elasticsearch Elasticsearch 8 Dec 15 23:25 index.latest -rw-rw-r-- 1 Elasticsearch Elasticsearch 29 Mar 11 2020 incompatible-snapshots drwxrwxr-x 28 Elasticsearch Elasticsearch 4.0K Aug 11 21:55 indices **/usr/share/Elasticsearch/data/backups/snap\_repo/indices** drwxrwxr-x 3 Elasticsearch Elasticsearch 4.0K Dec 15 23:25 oMof6-HiT9WqlyrHgCcSog drwxrwxr-x 3 Elasticsearch Elasticsearch 4.0K Dec 15 23:25 iVeUwp81RVaY0OEKxJMWog drwxrwxr-x 3 Elasticsearch Elasticsearch 4.0K Dec 15 23:25 hnt-tkcER8iAW\_6TsEmhOg drwxrwxr-x 3 Elasticsearch Elasticsearch 4.0K Dec 15 23:25 CrScXiJLSN2u6n\_lsFK4pg drwxrwxr-x 7 Elasticsearch Elasticsearch 4.0K Dec 15 23:25 ydFossuQTASNIQoFgcUo2w **/usr/share/Elasticsearch/data/backups/snap\_repo/indices/oMof6-HiT9WqlyrHgCcSog** -rw-rw-r-- 1 Elasticsearch Elasticsearch 1.4K Dec 13 22:50 meta-D8Ux12cqRPmrygR\_MFYnew.dat -rw-rw-r-- 1 Elasticsearch Elasticsearch 1.4K Dec 14 22:50 meta-O679iA7XRGmXeiydvYFDBQ.dat -rw-rw-r-- 1 Elasticsearch Elasticsearch 1.4K Dec 15 22:50 meta-GtSrbA44STaweZjEH5On9w.dat drwxrwxr-x 2 Elasticsearch Elasticsearch 16K Dec 15 23:25 0 **--\> Shard 0** **In Shard /0** **/usr/share/Elasticsearch/data/backups/snap\_repo/indices/oMof6-HiT9WqlyrHgCcSog/0** -rw-rw-r-- 1 Elasticsearch Elasticsearch 331 Dec 13 23:14 \_\_7ntQ7hRdQ8OtbtSOOyMAwQ ???? -rw-rw-r-- 1 Elasticsearch Elasticsearch 6.5K Dec 13 23:14 \_\_y5QKJx3jS4-4KbrGQwUP0g ???? -rw-rw-r-- 1 Elasticsearch Elasticsearch 366 Dec 13 23:14 \_\_mQr7yci9TraSyl2bo\_NtZw ???? -rw-rw-r-- 1 Elasticsearch Elasticsearch 384 Dec 13 23:14 \_\_VNnl\_uv2S0-bTmxqrRtCow ???? -rw-rw-r-- 1 Elasticsearch Elasticsearch 1.3K Dec 13 23:14 snap-D8Ux12cqRPmrygR\_MFYnew.dat -rw-rw-r-- 1 Elasticsearch Elasticsearch 331 Dec 14 23:36 \_\_owHfLo9sTsG3CRZsEccUUA ???? -rw-rw-r-- 1 Elasticsearch Elasticsearch 6.5K Dec 14 23:36 \_\_6zoFdfnCQ3iBZLnRdA7LjQ ???? -rw-rw-r-- 1 Elasticsearch Elasticsearch 366 Dec 14 23:36 \_\_jojncs8XSnGSS80Eb1b8Vw ???? -rw-rw-r-- 1 Elasticsearch Elasticsearch 384 Dec 14 23:36 \_\_qTHPjOvuRHOIec86yJ467w ???? -rw-rw-r-- 1 Elasticsearch Elasticsearch 1.3K Dec 14 23:36 snap-O679iA7XRGmXeiydvYFDBQ.dat -rw-rw-r-- 1 Elasticsearch Elasticsearch 366 Dec 15 23:24 \_\_j0uwN2DVTUOzQzROUXEcfQ ???? -rw-rw-r-- 1 Elasticsearch Elasticsearch 384 Dec 15 23:24 \_\_3CmrEzsPQUaweYiLyZJ\_xg ???? -rw-rw-r-- 1 Elasticsearch Elasticsearch 331 Dec 15 23:24 \_\_1g7ORrhERQ-XO7-1ylEozQ ???? -rw-rw-r-- 1 Elasticsearch Elasticsearch 6.5K Dec 15 23:24 \_\_sjydYk1KSK6a34ELGhT96A ???? -rw-rw-r-- 1 Elasticsearch Elasticsearch 1.3K Dec 15 23:24 snap-GtSrbA44STaweZjEH5On9w.dat drwxrwxr-x 3 Elasticsearch Elasticsearch 4.0K Dec 15 23:25 .. -rw-rw-r-- 1 Elasticsearch Elasticsearch 34K Dec 15 23:25 index-460 drwxrwxr-x 2 Elasticsearch Elasticsearch 16K Dec 15 23:25 . **In node A, inside shard 0, the files `__** ` are not generated, only the file 'snap- **\*\*\*\*\***.data'** **usr/share/Elasticsearch/data/backups/snap\_repo/indices/oMof6-HiT9WqlyrHgCcSog/0** -rw-rw-r-- 1 Elasticsearch Elasticsearch 1.3K Dec 13 23:14 snap-D8Ux12cqRPmrygR\_MFYnew.dat -rw-rw-r-- 1 Elasticsearch Elasticsearch 1.3K Dec 14 23:36 snap-O679iA7XRGmXeiydvYFDBQ.dat -rw-rw-r-- 1 Elasticsearch Elasticsearch 1.3K Dec 15 23:24 snap-GtSrbA44STaweZjEH5On9w.dat Looking forward for your reply.

Do you use shared file system? If you use shared file system and mount the same directory to the same path, it couldn't happen. > **[Register a snapshot repository | Elasticsearch Guide \[7.16\] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/current/snapshots-register-repository.html#snapshots-filesystem-repository)** ---
