rclone bisync
Perform bidirectional synchronization between two paths.
Synopsis
Perform bidirectional synchronization between two paths.
Bisync provides a bidirectional cloud sync solution in rclone. It retains the Path1 and Path2 filesystem listings from the prior run. On each successive run it will:
- list files on Path1 and Path2, and check for changes on each side. Changes include
New
,Newer
,Older
, andDeleted
files. - Propagate changes on Path1 to Path2, and vice-versa.
Bisync is in beta and is considered an advanced command, so use with care. Make sure you have read and understood the entire manual (especially the Limitations section) before using, or data loss can result. Questions can be asked in the Rclone Forum.
See full bisync description for details.
rclone bisync remote1:path1 remote2:path2 [flags]
Options
--backup-dir1 string --backup-dir for Path1. Must be a non-overlapping path on the same remote.
--backup-dir2 string --backup-dir for Path2. Must be a non-overlapping path on the same remote.
--check-access Ensure expected RCLONE_TEST files are found on both Path1 and Path2 filesystems, else abort.
--check-filename string Filename for --check-access (default: RCLONE_TEST)
--check-sync string Controls comparison of final listings: true|false|only (default: true) (default "true")
--compare string Comma-separated list of bisync-specific compare options ex. 'size,modtime,checksum' (default: 'size,modtime')
--conflict-loser ConflictLoserAction Action to take on the loser of a sync conflict (when there is a winner) or on both files (when there is no winner): , num, pathname, delete (default: num)
--conflict-resolve string Automatically resolve conflicts by preferring the version that is: none, path1, path2, newer, older, larger, smaller (default: none) (default "none")
--conflict-suffix string Suffix to use when renaming a --conflict-loser. Can be either one string or two comma-separated strings to assign different suffixes to Path1/Path2. (default: 'conflict')
--create-empty-src-dirs Sync creation and deletion of empty directories. (Not compatible with --remove-empty-dirs)
--download-hash Compute hash by downloading when otherwise unavailable. (warning: may be slow and use lots of data!)
--filters-file string Read filtering patterns from a file
--force Bypass --max-delete safety check and run the sync. Consider using with --verbose
-h, --help help for bisync
--ignore-listing-checksum Do not use checksums for listings (add --ignore-checksum to additionally skip post-copy checksum checks)
--max-lock Duration Consider lock files older than this to be expired (default: 0 (never expire)) (minimum: 2m) (default 0s)
--no-cleanup Retain working files (useful for troubleshooting and testing).
--no-slow-hash Ignore listing checksums only on backends where they are slow
--recover Automatically recover from interruptions without requiring --resync.
--remove-empty-dirs Remove ALL empty directories at the final cleanup step.
--resilient Allow future runs to retry after certain less-serious errors, instead of requiring --resync. Use at your own risk!
-1, --resync Performs the resync run. Equivalent to --resync-mode path1. Consider using --verbose or --dry-run first.
--resync-mode string During resync, prefer the version that is: path1, path2, newer, older, larger, smaller (default: path1 if --resync, otherwise none for no resync.) (default "none")
--slow-hash-sync-only Ignore slow checksums for listings and deltas, but still consider them during sync calls.
--workdir string Use custom working dir - useful for testing. (default: {WORKDIR})
Options shared with other commands are described next. See the global flags page for global options not listed here.
Copy Options
Flags for anything which can copy a file
--check-first Do all the checks before starting transfers
-c, --checksum Check for changes with size & checksum (if available, or fallback to size only)
--compare-dest stringArray Include additional server-side paths during comparison
--copy-dest stringArray Implies --compare-dest but also copies files from paths into destination
--cutoff-mode HARD|SOFT|CAUTIOUS Mode to stop transfers when reaching the max transfer limit HARD|SOFT|CAUTIOUS (default HARD)
--ignore-case-sync Ignore case when synchronizing
--ignore-checksum Skip post copy check of checksums
--ignore-existing Skip all files that exist on destination
--ignore-size Ignore size when skipping use modtime or checksum
-I, --ignore-times Don't skip items that match size and time - transfer all unconditionally
--immutable Do not modify files, fail if existing files have been modified
--inplace Download directly to destination file instead of atomic download to temp/rename
--max-backlog int Maximum number of objects in sync or check backlog (default 10000)
--max-duration Duration Maximum duration rclone will transfer data for (default 0s)
--max-transfer SizeSuffix Maximum size of data to transfer (default off)
-M, --metadata If set, preserve metadata when copying objects
--modify-window Duration Max time diff to be considered the same (default 1ns)
--multi-thread-chunk-size SizeSuffix Chunk size for multi-thread downloads / uploads, if not set by filesystem (default 64Mi)
--multi-thread-cutoff SizeSuffix Use multi-thread downloads for files above this size (default 256Mi)
--multi-thread-streams int Number of streams to use for multi-thread downloads (default 4)
--multi-thread-write-buffer-size SizeSuffix In memory buffer size for writing when in multi-thread mode (default 128Ki)
--no-check-dest Don't check the destination, copy regardless
--no-traverse Don't traverse destination file system on copy
--no-update-dir-modtime Don't update directory modification times
--no-update-modtime Don't update destination modtime if files identical
--order-by string Instructions on how to order the transfers, e.g. 'size,descending'
--partial-suffix string Add partial-suffix to temporary file name when --inplace is not used (default ".partial")
--refresh-times Refresh the modtime of remote files
--server-side-across-configs Allow server-side operations (e.g. copy) to work across different configs
--size-only Skip based on size only, not modtime or checksum
--streaming-upload-cutoff SizeSuffix Cutoff for switching to chunked upload if file size is unknown, upload starts after reaching cutoff or when file ends (default 100Ki)
-u, --update Skip files that are newer on the destination
Important Options
Important flags useful for most commands
-n, --dry-run Do a trial run with no permanent changes
-i, --interactive Enable interactive mode
-v, --verbose count Print lots more stuff (repeat for more)
