vmrestore

vmrestore restores data from backups created by vmbackup. VictoriaMetrics v1.28.4 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 name.
• <path/to/backup> is the path to backup made with vmbackup 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.

Advanced usage

Run vmrestore -help in order to see all the available options:

How to build from sources

It is recommended using binary releases - see vmutils-* archives there.

Development build

1. Install Go. 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.
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.
