    Limitations

    This can only write files seqentially, it can only seek when reading. This means that many applications won't work with their files on an rclone mount.

    The bucket based remotes (eg Swift, S3, Google Compute Storage, B2, Hubic) won't work from the root - you will need to specify a bucket, or a path within the bucket. So swift: won't work whereas swift:bucket will as will swift:bucket/path. None of these support the concept of directories, so empty directories will have a tendency to disappear once they fall out of the directory cache.

    rclone mount vs rclone sync/copy

    File systems expect things to be 100% reliable, whereas cloud storage systems are a long way from 100% reliable. The rclone sync/copy commands cope with this with lots of retries. However rclone mount can't use retries in the same way without making local copies of the uploads. This might happen in the future, but for the moment rclone mount won't do that, so will be less reliable than the rclone command.

    Options which use SIZE use kByte by default. However a suffix of b for bytes, k for kBytes, M for MBytes and G for GBytes may be used. These are the binary units, eg 1, 2**10, 2**20, 2**30 respectively.

    --bwlimit=BANDWIDTH_SPEC

    This option controls the bandwidth limit. Limits can be specified in two ways: As a single limit, or as a timetable.

    Single limits last for the duration of the session. To use a single limit, specify the desired bandwidth in kBytes/s, or use a suffix b|k|M|G. The default is 0 which means to not limit bandwidth.

    -

    For example to limit bandwidth usage to 10 MBytes/s use --bwlimit 10M

    It is also possible to specify a "timetable" of limits, which will cause certain limits to be applied at certain times. To specify a timetable, format your entries as "HH:MM,BANDWIDTH HH:MM,BANDWITH...".

    It is also possible to specify a "timetable" of limits, which will cause certain limits to be applied at certain times. To specify a timetable, format your entries as "HH:MM,BANDWIDTH HH:MM,BANDWIDTH...".

    An example of a typical timetable to avoid link saturation during daytime working hours could be:

    --bwlimit "08:00,512 12:00,10M 13:00,512 18:00,30M 23:00,off"

    In this example, the transfer bandwidth will be set to 512kBytes/sec at 8am. At noon, it will raise to 10Mbytes/s, and drop back to 512kBytes/sec at 1pm. At 6pm, the bandwidth limit will be set to 30MBytes/s, and at 11pm it will be completely disabled (full speed). Anything between 11pm and 8am will remain unlimited.

    Bandwidth limits only apply to the data transfer. They don't apply to the bandwidth of the directory listings etc.

    -

    Note that the units are Bytes/s not Bits/s. Typically connections are measured in Bits/s - to convert divide by 8. For example let's say you have a 10 Mbit/s connection and you wish rclone to use half of it - 5 Mbit/s. This is 5/8 = 0.625MByte/s so you would use a --bwlimit 0.625M parameter for rclone.

    This may be used to increase performance of --tpslimit without changing the long term average number of transactions per second.

    By default, rclone doesn't keep track of renamed files, so if you rename a file locally then sync it to a remote, rclone will delete the old file on the remote and upload a new copy.

    If you use this flag, and the remote supports server side copy or server side move, and the source and destination have a compatible hash, then this will track renames during sync, copy, and move operations and perform renaming server-side.

    Files will be matched by size and hash - if both match then a rename will be considered.

    If the destination does not support server-side copy or move, rclone will fall back to the default behaviour and log an error level message to the console.

    Specifying --delete-after (the default value) will delay deletion of files until all new/updated files have been successfully transferred. The files to be deleted are collected in the copy pass then deleted after the copy pass has completed successfully. The files to be deleted are held in memory so this mode may use more memory. This is the safest mode as it will only delete files if there have been no errors subsequent to that. If there have been errors before the deletions start then you will get the message not deleting files as there were IO errors.

    --fast-list

    When doing anything which involves a directory listing (eg sync, copy, ls - in fact nearly every command), rclone normally lists a directory and processes it before using more directory lists to process any subdirectories. This can be parallelised and works very quickly using the least amount of memory.

    However some remotes have a way of listing all files beneath a directory in one (or a small number) of transactions. These tend to be the bucket based remotes (eg s3, b2, gcs, swift, hubic).

    However, some remotes have a way of listing all files beneath a directory in one (or a small number) of transactions. These tend to be the bucket based remotes (eg S3, B2, GCS, Swift, Hubic).

    If you use the --fast-list flag then rclone will use this method for listing directories. This will have the following consequences for the listing:
