NAME

plakar-backup — Create a new snapshot in a Kloset store

SYNOPSIS

DESCRIPTION

The plakar backup command creates a new snapshot of place, or the current directory. Snapshots can be filtered to ignore specific files or directories based on patterns provided through options.

place can be either a path, an URI, or a label with the form “@name” to reference a source connector configured with plakar-source(1).

The options are as follows:

-cache path

Specify a path to store the vfs cache. Use the special value ‘no’ to disable caching. Use the special value ‘vfs’ to use the in-memory vfs cache (the default).

-category category

Set the snapshot category.

-check

Perform a full check on the backup after success.

-dry-run

Do not write a snapshot; instead, perform a dry run by outputting the list of files and directories that would be included in the backup. Respects all exclude patterns and other options, but makes no changes to the Kloset store.

-environment environment

Set the snapshot environment.

-force-timestamp timestamp

Specify a fixed timestamp (in ISO 8601 or relative human format) to use for the snapshot. Could be used to reimport an existing backup with the same timestamp.

-ignore pattern

Specify individual gitignore exclusion patterns to ignore files or directories in the backup. This option can be repeated.

-ignore-file file

Specify a file containing gitignore exclusion patterns, one per line, to ignore files or directories in the backup.

-job job

Name the snapshot job.

-name name

Name the snapshot.

-no-progress

Do not compute or display progress. By default, plakar backup does two passes on the source of the backup: one to compute the number of items, and a second for processing the items themselves. This flag disables the pass to compute the number of items. It is set implicitly for some importer connectors that don't support the two-passes.

-no-xattr

Skip extended attributes (xattrs) when creating the backup.

-o option=value

Can be used to pass extra arguments to the source connector. The given option takes precedence over the configuration file.

-packfiles path

Path where to put the temporary packfiles instead of building them in the default temporary directory. If the special value ‘memory’ is specified then the packfiles are built in memory.

-perimeter perimeter

Set the snapshot perimeter.

-tag tag

Comma-separated list of tags to apply to the snapshot.

ENVIRONMENT

PLAKAR_TAGS

Comma-separated list of tags to apply to the snapshot during backup. Overridden by the -tag command-line flag.

EXIT STATUS

The plakar-backup utility exits 0 on success, and >0 if an error occurs.

EXAMPLES

Create a snapshot of the current directory with two tags:

$ plakar backup -tag daily-backup,production

Ignore files using patterns in a given file:

$ plakar backup -ignore-file ~/my-ignore-file /var/www

or by using patterns specified inline:

$ plakar backup -ignore "*.tmp" -ignore "*.log" /var/www

Pass an option to the importer, in this case to don't traverse mount points:

$ plakar backup -o dont_traverse_fs=true /
