The VictoriaMetrics backup manager automates regular backup procedures. It supports the following backup intervals: **hourly**, **daily**, **weekly** and **monthly**.
Multiple backup intervals may be configured simultaneously. I.e. the backup manager creates hourly backups every hour, while it creates daily backups every day, etc.
Backup manager must have read access to the storage data, so best practice is to install it on the same machine (or as a sidecar) where the storage node is installed.
The backup service makes a backup every hour and puts it to the latest folder and then copies data to the folders
which represent the backup intervals (hourly, daily, weekly and monthly)
* -snapshot.createURL - VictoriaMetrics creates snapshot URL which will automatically be created during backup. Example: <http://victoriametrics:8428/snapshot/create>
* -dst - backup destination at [the supported storage types](https://docs.victoriametrics.com/vmbackup.html#supported-storage-types).
* -credsFilePath - path to file with GCS or S3 credentials. Credentials are loaded from default locations if not set.

> *Note*: 0 value in every keepLast flag results into deletion of ALL backups for particular type (hourly, daily, weekly and monthly)
> *Note*: retention policy does not enforce removing previous versions of objects in object storages such if versioning is enabled. See [these docs](https://docs.victoriametrics.com/vmbackup.html#permanent-deletion-of-objects-in-s3-and-compatible-storages) for more details.
See operator `VMStorage` schema [here](https://docs.victoriametrics.com/operator/api.html#vmstorage) and `VMSingle` [here](https://docs.victoriametrics.com/operator/api.html#vmsinglespec).
These steps are assuming that [VictoriaMetrics operator](https://docs.victoriametrics.com/operator/VictoriaMetrics-Operator.html) is used to manage `VMCluster`.
Clusters here are referred to as `source` and `destination`.
1. Create a new cluster with access to *source* cluster `vmbackupmanager` storage and same number of storage nodes.
Add the following section in order to enable restore on start (operator `VMStorage` schema can be found [here](https://docs.victoriametrics.com/operator/api.html#vmstorage):
`vmbackupmanager` exports various metrics in Prometheus exposition format at `http://vmbackupmanager:8300/metrics` page. It is recommended setting up regular scraping of this page
either via [vmagent](https://docs.victoriametrics.com/vmagent.html) or via Prometheus, so the exported metrics could be analyzed later.
Use the official [Grafana dashboard](https://grafana.com/grafana/dashboards/17798-victoriametrics-backupmanager/) for `vmbackupmanager` overview.
Graphs on this dashboard contain useful hints - hover the `i` icon in the top left corner of each graph in order to read it.
If you have suggestions for improvements or have found a bug - please open an issue on github or add
Profile name for S3 configs. If no set, the value of the environment variable will be loaded (AWS_PROFILE or AWS_DEFAULT_PROFILE), or if both not set, DefaultSharedConfigProfile is used
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
Whether to prune previous object versions when deleting an object. By default, when object storage has versioning enabled deleting the file removes only current version. This option forces removal of all previous versions. See: https://docs.victoriametrics.com/vmbackup.html#permanent-deletion-of-objects-in-s3-compatible-storages
Whether to enable reading flags from environment variables in addition to the command line. Command line flag values have priority over values from environment vars. Flags are read only from the command line if this flag isn't set. See https://docs.victoriametrics.com/#environment-variables for more details
Deprecated, please use -license or -licenseFile flags instead. By specifying this flag, you confirm that you have an enterprise license and accept the ESA https://victoriametrics.com/legal/esa/ . This flag is available only in VictoriaMetrics enterprise. See https://docs.victoriametrics.com/enterprise.html
Whether to use pread() instead of mmap() for reading data files. By default, mmap() is used for 64-bit arches and pread() is used for 32-bit arches, since they cannot read data files bigger than 2^32 bytes in memory. mmap() is usually faster for reading small data chunks than pread()
Incoming http connections are closed after the configured timeout. This may help to spread the incoming load among a cluster of services behind a load balancer. Please note that the real timeout may be bigger by up to 10% as a protection against the thundering herd problem (default 2m0s)
The maximum duration for a graceful shutdown of the HTTP server. A highly loaded server may require increased value for a graceful shutdown (default 7s)
An optional prefix to add to all the paths handled by http server. For example, if '-http.pathPrefix=/foo/bar' is set, then all the http requests will be handled on '/foo/bar/*' paths. This may be useful for proxied requests. See https://www.robustperception.io/using-external-urls-and-proxies-with-prometheus
Optional delay before http server shutdown. During this delay, the server returns non-OK responses from /health page, so load balancers can route new requests to other servers
The expiry duration for caches for interned strings. See https://en.wikipedia.org/wiki/String_interning . See also -internStringMaxLen and -internStringDisableCache (default 6m0s)
-internStringDisableCache
Whether to disable caches for interned strings. This may reduce memory usage at the cost of higher CPU usage. See https://en.wikipedia.org/wiki/String_interning . See also -internStringCacheExpireDuration and -internStringMaxLen
The maximum length for strings to intern. A lower limit may save memory at the cost of higher CPU usage. See https://en.wikipedia.org/wiki/String_interning . See also -internStringDisableCache and -internStringCacheExpireDuration (default 500)

Per-second limit on the number of ERROR messages. If more than the given number of errors are emitted per second, the remaining errors are suppressed. Zero values disable the rate limit
Timezone to use for timestamps in logs. Timezone must be a valid IANA Time Zone. For example: America/New_York, Europe/Berlin, Etc/GMT+3 or Local (default "UTC")
Per-second limit on the number of WARN messages. If more than the given number of warns are emitted per second, then the remaining warns are suppressed. Zero values disable the rate limit
Allowed size of system memory VictoriaMetrics caches may occupy. This option overrides -memory.allowedPercent if set to a non-zero value. Too low a value may increase the cache miss rate usually resulting in higher CPU and disk IO usage. Too high a value may evict too much data from the OS page cache resulting in higher disk IO usage
Allowed percent of system memory VictoriaMetrics caches may occupy. See also -memory.allowedBytes. Too low a value may increase cache miss rate usually resulting in higher CPU and disk IO usage. Too high a value may evict too much data from the OS page cache which will result in higher disk IO usage (default 60)
Optional labels to add to metrics pushed to -pushmetrics.url . For example, -pushmetrics.extraLabel='instance="foo"' adds instance="foo" label to all the metrics pushed to -pushmetrics.url
Optional URL to push metrics exposed at /metrics page. See https://docs.victoriametrics.com/#push-metrics . By default, metrics exposed at /metrics page aren't pushed to any remote storage
VictoriaMetrics create snapshot url. When this is given a snapshot will automatically be created during backup.Example: http://victoriametrics:8428/snapshot/create
VictoriaMetrics delete snapshot url. Optional. Will be generated from snapshot.createURL if not provided. All created snaphosts will be automatically deleted.Example: http://victoriametrics:8428/snapshot/delete
Path to file with TLS certificate if -tls is set. Prefer ECDSA certs instead of RSA certs as RSA certs are slower. The provided certificate file is automatically re-read every second, so it can be dynamically updated
Optional list of TLS cipher suites for incoming requests over HTTPS if -tls is set. See the list of supported cipher suites at https://pkg.go.dev/crypto/tls#pkg-constants
Supports an array of values separated by comma or specified via multiple flags.
