## vmrestore
|
||
|
|
|
||
|
|
`vmrestore` restores data from backups created by [vmbackup](https://github.com/VictoriaMetrics/VictoriaMetrics/blob/master/app/vmbackup/README.md).
|
||
|
|
VictoriaMetrics `v1.29.0` and newer versions must be used for working with the restored data.
|
||
|
|
|
||
|
|
Restore process can be interrupted at any time. It is automatically resumed from the inerruption point
|
||
|
|
when restarting `vmrestore` with the same args.
|
||
|
|
|
||
|
|
|
||
|
|
### Usage
|
||
|
|
|
||
|
|
VictoriaMetrics must be stopped during the restore process.
|
||
|
|
|
||
|
|
```
|
||
|
|
vmrestore -src=gcs://<bucket>/<path/to/backup> -storageDataPath=<local/path/to/restore>
|
||
|
|
|
||
|
|
```
|
||
|
|
|
||
|
|
* `<bucket>` is [GCS bucket](https://cloud.google.com/storage/docs/creating-buckets) name.
|
||
|
|
* `<path/to/backup>` is the path to backup made with [vmbackup](https://github.com/VictoriaMetrics/VictoriaMetrics/blob/master/app/vmbackup/README.md) on GCS bucket.
|
||
|
|
* `<local/path/to/restore>` is the path to folder where data will be restored. This folder must be passed
|
||
|
|
to VictoriaMetrics in `-storageDataPath` command-line flag after the restore process is complete.
|
||
|
|
|
||
|
|
The original `-storageDataPath` directory may contain old files. They will be susbstituted by the files from backup.
|
||
|
|
|
||
|
|
|
||
|
|
### Troubleshooting
|
||
|
|
|
||
|
|
* If `vmrestore` eats all the network bandwidth, then set `-maxBytesPerSecond` to the desired value.
|
||
|
|
* If `vmrestore` has been interrupted due to temporary error, then just restart it with the same args. It will resume the restore process.
|
||
|
|
|
||
|
|
|
||
|
|
### Advanced usage
|
||
|
|
|
||
|
|
Run `vmrestore -help` in order to see all the available options:
|
||
|
|
|
||
|
|
```
|
||
|
|
-concurrency int
|
||
|
|
The number of concurrent workers. Higher concurrency may reduce restore duration (default 10)
|
||
|
|
-configFilePath string
|
||
|
|
Path to file with S3 configs. Configs are loaded from default location if not set.
|
||
|
|
See https://docs.aws.amazon.com/general/latest/gr/aws-security-credentials.html
|
||
|
|
-configProfile string
|
||
|
|
Profile name for S3 configs (default "default")
|
||
|
|
-credsFilePath string
|
||
|
|
Path to file with GCS or S3 credentials. Credentials are loaded from default locations if not set.
|
||
|
|
See https://cloud.google.com/iam/docs/creating-managing-service-account-keys and https://docs.aws.amazon.com/general/latest/gr/aws-security-credentials.html
|
||
|
|
-customS3Endpoint string
|
||
|
|
Custom S3 endpoint for use with S3-compatible storages (e.g. MinIO). S3 is used if not set
|
||
|
|
-loggerLevel string
|
||
|
|
Minimum level of errors to log. Possible values: INFO, ERROR, FATAL, PANIC (default "INFO")
|
||
|
|
-maxBytesPerSecond int
|
||
|
|
The maximum download speed. There is no limit if it is set to 0
|
||
|
|
-memory.allowedPercent float
|
||
|
|
Allowed percent of system memory VictoriaMetrics caches may occupy (default 60)
|
||
|
|
-src string
|
||
|
|
Source path with backup on the remote storage. Example: gcs://bucket/path/to/backup/dir, s3://bucket/path/to/backup/dir or fs:///path/to/local/backup/dir
|
||
|
|
-storageDataPath string
|
||
|
|
Destination path where backup must be restored. VictoriaMetrics must be stopped when restoring from backup. -storageDataPath dir can be non-empty. In this case only missing data is downloaded from backup (default "victoria-metrics-data")
|
||
|
|
-version
|
||
|
|
Show VictoriaMetrics version
|
||
|
|
```
|

### How to build from sources
|
||
|
|
|
||
|
|
It is recommended using [binary releases](https://github.com/VictoriaMetrics/VictoriaMetrics/releases) - see `vmutils-*` archives there.
|
||
|
|
|
||
|
|
|
||
|
|
#### Development build
|
||
|
|
|
||
|
|
1. [Install Go](https://golang.org/doc/install). The minimum supported version is Go 1.12.
|
||
|
|
2. Run `make vmrestore` from the root folder of the repository.
|
||
|
|
It builds `vmrestore` binary and puts it into the `bin` folder.
|
||
|
|
|
||
|
|
#### Production build
|
||
|
|
|
||
|
|
1. [Install docker](https://docs.docker.com/install/).
|
||
|
|
2. Run `make vmrestore-prod` from the root folder of the repository.
|
||
|
|
It builds `vmrestore-prod` binary and puts it into the `bin` folder.
|
||
|
|
|
||
|
|
#### Building docker images
|
||
|
|
|
||
|
|
Run `make package-vmrestore`. It builds `victoriametrics/vmrestore:<PKG_TAG>` docker image locally.
|
||
|
|
`<PKG_TAG>` is auto-generated image tag, which depends on source code in the repository.
|
||
|
|
The `<PKG_TAG>` may be manually set via `PKG_TAG=foobar make package-vmrestore`.
