![]() I hesitate whether to abandon OMV and switch to Qnap original OS (haven't tried it yet), or get used to making backup through Ethernet 2.5GbE and to USB backup disk connected to Windows. I have no idea if the problem might be with USB driver. For ntfs I tried also up to date ntfs-3g driver from 2021. For ntfs I disabled indexing, for ext4 I didn't know how to do it. I used fdisk and mkfs for preparing external usb hdd. I also tried a larger external WD disk, with no improvement. The USB backup disk is WD Elements 14TB, connected to NAS front USB3 socket. System drive is a fast Samsung 256GB pendrive connected to rear USB3. ![]() 2x internal, separate RAIDs-1 on WD REDs PLUS. I tried OMV5 and OMV6, the later is now running. Is it logical that writing to USB disk is so slow with OMV? However it would be more comfortable for me to connect the backup USB disk directly to OMV server and leave it making backup for several hours or so. The speed is several times faster than with the USB disk connected directly to OMV. The data is copied from OMV through 2.5GbE network to Windows, and then to the USB disk. The Top 11 Free and Open Source File Sync Software Published on : NovemBy : Jemimah Rodriguez File synchronization ensures that two or more data storage devices, computers, or programs have the same information at a given time. The target backup would be with rsync (from the internal raid-1 to the external usb disk).Īctually a moment ago I gave up making backup on OMV and connected the external usb hdd to Windows, and syncing files (using FreeFileSync software) goes with speed around 170MB/s for large files. I copy one very large file for a start (185GB). ![]() The starting copy speed is above 100MB/s, ok, but after a while speed decreases to 25MB/s approximately. ![]() APPLE M1 Silicon Slow compare with network volume (samba) er.alekh. You could run a compare, then use the boxes at the bottom to toggle what the results will show you. The best Android alternative is Syncthing, which is both free and Open Source. Okay, lets round progress percentage numbers down in the next FreeFileSync release. Keeps the data on all of your devices synchronized with real-time, automated, and unattended synchronization service. It was very slow (average 25MB/s) so I thought it might by the problem of slow ntfs implementation. FreeFileSync is not available for Android but there are some alternatives with similar functionality. Ensures full data redundancy and ease of recovery with multiple backup options. Reading large files from USB disk is ~160MB/s, writing 25MB/s. I experience very slow writing backup to external USB disk. Ignored errors: Check if FreeFileSync reported errors during comparison. ![]()
