SyncBack Freeware

For the file/folder-backup Duplicati is the best free app
For a good backup functionality is is necessary to cleanup more/older than x backups (CLU) not only older backups than x months, and to configure the schedule of a backup also for each 2nd Monday 10:00 and to pause if the system is busy (Sch).
Comparison of file/folder backup applications:
Comparison ...... CLU . Sch . Lang
SyncBack Free...... No ... Yes .. English only
Cobian Backup .. Yes .. No ... Many
Acronis True Im.. Yes .. Yes .. Many
Duplicati ...............Yes .. Yes .. Dan.En.Fr.Port.
Areca Backup ..... No .. Yes .. English only
Personal Backup No .. Yes .. Engl.+German
Saft Backup .........Yes .. No .. Engl.+German

Duplicati (1) is the best free backup application.
Acronis True Image (2) has all necessary functions, has multi-language UI and additionally can do harddisk images with best functions, but it is not free.
In difference to Duplicati Saft Backup can do backups with volume shadow copy (VSS), but cannot do a backup on each second Monday and has no flexible file filter.

SyncBack has no automatical symmetrical file-deletion
No automatical file-deletion at the other side (equal which side) of a sync-folder-pair, if file-deletion-time was later than last-file-change-time at the side, where the file still exists, see screenshot.
Sync-Apps with symmetrical auto-file-deletion are: Allway Sync, PureSync, Synkron.

No other free application than Allway Sync is able to sync directly and reliable a WebDAV-Folder or SD-Memory-Card from a "Windows Mobile" SmartPhone with a Vista PC Folder.
After detailed comparison with many other syncing applications I recommend Allway Sync as the best one, if you have no problems with the restriction of max. 40000 files per months for free private use.

This program is by far the most sensible no hassle backup/synchronisation software in the www. Love these guys for releasing a freeware old version. Hopefully when my needs require it, I will buy the SE new version because they know how to make software that just works. Thank you!
