Backup options¶
backup:
priority:
"localhost:28019": 2.5
"localhost:27018": 2.5
"localhost:27020": 2.0
"localhost:27017": 0.1
compression: <string>
compressionLevel: <int>
priority¶
Type: array of strings
The list of mongod nodes and their priority for making backups. The node with the highest priority is elected for making a backup. If several nodes have the same priority, the one among them is randomly elected to make a backup.
If not set, the replica set nodes have the default priority as follows:
- hidden nodes - 2.0
- secondary nodes - 1.0
- primary node - 0.5
backup.compression¶
Type: string
Default: s2
The compression method for backup snapshots. Available in Percona Backup for MongoDB as of version 1.8.0.
When none is specified, backups are made without compression.
Supported values: gzip, snappy, lz4, s2, pgzip, zstd. Default: s2.
backup.compressionLevel¶
Type: int
The compression level. The default value depends on the compression method used.
The following table shows available compression levels per compression method:
| Compression method | Supported compression levels | Default |
|---|---|---|
zstd |
1 - fastest speed, 2 - default, 3 - better compression, 4 - best compression | 2 |
snappy |
no levels | |
lz4 |
From 1 (fastest) to 16 | 1 |
gzip and pgzip |
-1 - default compression, 0 - no compression, 1 - best speed, 9 - best compression | -1 |
Note that the higher value you specify, the more time and computing resources it will take to compress the data.
