# Storage Location for Transaction Logs and Snapshots

The `datadir` engine variable stores the location of transaction logs and snapshots. Transaction logs are typically stored in the `/var/lib/memsql/<node_ID>/data/logs` directory with the log file names resembling the following format: `metrics_3_log_v1_15335424`. In this example,

* `metrics` is the database name
* `3` is the partition number
* `log` is the file type
* `v1` is the file format version number
* `15335424` is the log sequence number (LSN)

Snapshots are typically located in the `/var/lib/memsql/<node_ID>/data/snapshots` directory with the snapshot names resembling the following format: `memsql_snapshot_v1_0_28`. In this example,

* `memsql` is the name of the source database
* `snapshot` is the file type
* `v1` is the file format version number
* the remaining characters represent the sequence number
