The result on the GCS bucket. We see only 3 daily backups:
![daily](vmbackupmanager_rp_daily_2.png)
## Configuration
### Flags
Pass `-help` to `vmbackupmanager` in order to see the full list of supported
command-line flags with their descriptions.
The shortlist of configuration flags is the following:
```
vmbackupmanager performs regular backups according to the provided configs.
-concurrency int
The number of concurrent workers. Higher concurrency may reduce backup 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. 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
-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
-disableDaily
Disable daily run. Default false
-disableHourly
Disable hourly run. Default false
-disableMonthly
Disable monthly run. Default false
-disableWeekly
Disable weekly run. Default false
-dst string
The root folder of Victoria Metrics backups. Example: gs://bucket/path/to/backup/dir, s3://bucket/path/to/backup/dir or fs:///path/to/local/backup/dir
-enableTCP6
Whether to enable IPv6 for listening and dialing. By default only IPv4 TCP and UDP is used
-envflag.enable
Whether to enable reading flags from environment variables additionally to command line. Command line flag values have priority over values from environment vars. Flags are read only from command line if this flag isn't set. See https://docs.victoriametrics.com/#environment-variables for more details
-envflag.prefix string
Prefix for environment variables if -envflag.enable is set
-eula
By specifying this flag, you confirm that you have an enterprise license and accept the EULA https://victoriametrics.com/assets/VM_EULA.pdf
-fs.disableMmap
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()
-http.connTimeout duration
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)
-http.disableResponseCompression
Disable compression of HTTP responses to save CPU resources. By default compression is enabled to save network bandwidth
-http.idleConnTimeout duration
Timeout for incoming idle http connections (default 1m0s)
-http.maxGracefulShutdownDuration duration
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)
-http.pathPrefix string
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
-http.shutdownDelay duration
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
-httpAuth.password string
Password for HTTP Basic Auth. The authentication is disabled if -httpAuth.username is empty
-httpAuth.username string
Username for HTTP Basic Auth. The authentication is disabled if empty. See also -httpAuth.password
-httpListenAddr string
Address to listen for http connections (default ":8300")
-keepLastDaily int
Keep last N daily backups. If 0 is specified next retention cycle removes all backups for given time period. (default -1)
-keepLastHourly int
Keep last N hourly backups. If 0 is specified next retention cycle removes all backups for given time period. (default -1)
-keepLastMonthly int
Keep last N monthly backups. If 0 is specified next retention cycle removes all backups for given time period. (default -1)
-keepLastWeekly int
Keep last N weekly backups. If 0 is specified next retention cycle removes all backups for given time period. (default -1)
-loggerDisableTimestamps
Whether to disable writing timestamps in logs
-loggerErrorsPerSecondLimit int
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
-loggerFormat string
Format for logs. Possible values: default, json (default "default")
-loggerLevel string
Minimum level of errors to log. Possible values: INFO, WARN, ERROR, FATAL, PANIC (default "INFO")
-loggerOutput string
Output for the logs. Supported values: stderr, stdout (default "stderr")
-loggerTimezone string
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")
-loggerWarnsPerSecondLimit int
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
-maxBytesPerSecond int
The maximum upload speed. There is no limit if it is set to 0
-memory.allowedBytes size
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 OS page cache resulting in higher disk IO usage
Supports the following optional suffixes for size values: KB, MB, GB, KiB, MiB, GiB (default 0)
-memory.allowedPercent float
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 OS page cache which will result in higher disk IO usage (default 60)
-metricsAuthKey string
Auth key for /metrics. It must be passed via authKey query arg. It overrides httpAuth.* settings
-pprofAuthKey string
Auth key for /debug/pprof. It must be passed via authKey query arg. It overrides httpAuth.* settings
-runOnStart
Upload backups immediately after start of the service. Otherwise the backup starts on new hour
-s3ForcePathStyle
Prefixing endpoint with bucket name when set false, true by default. (default true)
-snapshot.createURL string
VictoriaMetrics create snapshot url. When this is given a snapshot will automatically be created during backup.Example: http://victoriametrics:8428/snapshot/create
-snapshot.deleteURL string
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
-storageDataPath string
Path to VictoriaMetrics data. Must match -storageDataPath from VictoriaMetrics or vmstorage (default "victoria-metrics-data")
-tls
Whether to enable TLS for incoming HTTP requests at -httpListenAddr (aka https). -tlsCertFile and -tlsKeyFile must be set if -tls is set
-tlsCertFile string
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
-tlsCipherSuites array
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.
-tlsKeyFile string
Path to file with TLS key if -tls is set. The provided key file is automatically re-read every second, so it can be dynamically updated
-version
Show VictoriaMetrics version
